The closer the number of valence electrons is to the number required to completely fill or deplete its outer shell the more likely the atom is to react. The most reactive kind of metallic element is a metal from Group 1 (e.g. The valence electrons are less tightly bound and easier to remove because they are farther away from the nucleus of the atom. The reactivity of a metal is determined by how tightly the metal holds onto the electrons in its outermost energy level. Answers: 1 … Combining Elements Activity Combine sodium and fluorine. element a is more reactive. The number of electrons in an atom’s outermost valence shell governs its behaviour. More valence electrons adds mass to the atom, making it less reactive Log in. A full valence energy level usually helps an atom be more chemically stable. The stability of the electrons in atoms determines not only the reactivity of an atom but its valence and the type of chemical bonds it can form. How many electrons does a fluorine atom have in its second shell? 0. That is why whose atoms have the same number of are grouped together in. To predict molecular shape, we usually use a theory called the valence shell electron pair (VSEPR) repulsion theory. ##Mg^(2+)## with an ##s^2p^6## configuration. Combine lithium and fluorine. A nonmetal tends to attract additional valence electrons to attain a full valence shell. The are the electrons in the outermost electron shell of an atom. The most reactive kind of nonmetal is a halogen such as fluorine or chlorine. Find more answers. OC2735157. Add your answer and earn points. A nonmetal tends to attract additional valence electrons to attain a full valence shell. Thus, the 18-electron rule is often a recipe for non-reactivity in either a stoichiometric or a catalytic sense. Describe the reactivity of the example elements in the slide show. These electrons participate in bonding and affect the reactivity of a substance. Each square on the periodic table contains the letter symbol for an element printed directly below the atomic number of the element. Describe how they bond. It is well known to us that the outermost shell of an atom processes maximum 8 number of electrons. These elements are highly reactive. How does this help explain the difference in the reactivity of metals within a group? Explain how position on the periodic table relates to an element’s reactivity. You have 1 free answer left. OC2735157. How does the number of valence electrons affect the reactivity? KaybayHaybay KaybayHaybay The less valence electrons the more reactive the element is. Combining Elements Activity Combine sodium and fluorine. The no. It is well known to us that the outermost shell of an atom processes maximum 8 number of electrons. The number of electrons in an atom’s outermost valence shell governs its behaviour. These electrons are called valence electrons. Fewer electrons means high reactivity. Therefore a metal from the bottom of Group 1 (like potassium) and a nonmetal from the top of Group 17 (like fluorine) will react violently because they both benefit greatly from the reaction. The number of electrons in the outermost shell of an atom determines its reactivity. Already have an account? In fact oxygen (the lightest element in Group 16) is more reactive than chlorine even though it is not a halogen because the valence electrons of oxygen are closer to the nucleus (at a lower energy). Combining Elements Activity Combine sodium and fluorine. Describe how they bond. An atom in Group 1 has only a single valence electron. This tendency is called the because the bonded atoms have eight valence electrons. The protons attract and hold the electrons, but the farther away the electrons are, the less the attractive force. The number of electrons in an atom's outermost valence shell governs its behaviour. 0. ##Na^+## or ##K^+##). Accordingly, valence electrons directly influence how elements behave in a chemical reaction. sodium or potassium). Ask your question. A metal from Group 2 (e.g. How many electrons does a fluorine atom have in its second shell? Already have an account? Complexes with fewer than 18 valence electrons tend to show enhanced reactivity. Metals usually have fewer valence electrons than nonmetals. ★★★ Correct answer to the question: How can the number of valence electrons in an atom be determined and how does the number of valence electrons an element posses affect its behavior and properties? That is why whose atoms have the same number of are grouped together in . Valence electrons are the electrons on the outer-most shell of an element. The valence electrons of the larger atoms are farther from the nucleus and are easier to remove, so the metals near the top are more reactive than those at the bottom. To form an ionic bond a halogen atom can remove an electron from another atom in order to form an anion (e.g. When the outer energy level is almost empty the atom wants to give up their few valence electrons so they can have a full outer energy level. In fact oxygen (the lightest element in Group 16) is more reactive than chlorine even though it is not a halogen because the valence electrons of oxygen are closer to the nucleus (at a lower energy). ##F^- Cl^-## etc.). That is why whose atoms have the same number of are grouped together in . How do valence electrons affect reactivity. The valence electron plays a vital role in atomic chemistry. I want to help you achieve the grades you (and I) know you are capable of; these grades are the stepping stone to your future. As per the bonding theory, particles which have valence electrons share them … Unlock this answer. A metal from Group 2 (e.g. Valence electrons can influence various properties of an element--from reactivity to energy level. How do valence electrons affect the reactivity of elements? Take this quiz to test how well you can identify how many electrons some elements possess. Find more answers. METALS The are the electrons in the outermost electron shell of an atom. Log in. The less valence electrons there are, the less stable the atom becomes, causing it to react with other atoms. Valence Electrons. It can either share electrons with a neighboring atom to form a covalent bond or it can remove electrons from another atom to form an ionic bond. Carbon—group 4: Chlorine—group 7: Explain how position on the periodic table relates to an element’s reactivity. The Alkali Metals (Group 1) have the highest tendency to lose electrons, making them the most reactive of the metals. Generally elements in Groups 1 2 and 13 to 17 tend to react to form a closed shell corresponding to the ##s^2p^6##. Finding Valence Electrons for All Elements Except Transition Metals. The location of electrons in an atom can be described as concentric shells around the nucleus of the atom. Rules for Writing Lewis Structures. NONMETALS ##K## loses one electron to ##F## and forms the ionic compound potassium fluoride ##K^+F^-##. How does this help explain the difference in the reactivity of metals within a group? This one valence electron is easily lost to form a positive ion with an ##s^2p^6## configuration (e.g. - edu-answer.com element a is more reactive. Within each Group of nonmetals reactivity decreases from top to bottom because the valence electrons are at progressively higher energies and the atoms do not gain much stability by gaining electrons. With other electrons in an atom the shells are full and they have little if any affect on the reactivity of an atom. How do valence electrons affect reactivity? To form a covalent bond one electron from the halogen and one electron from another atom form a shared pair (e.g. Combine lithium and fluorine. NONMETALS how does its reactivity compare to that of element b, which has four valence electrons? The valence electrons are less tightly bound and easier to remove because they are farther away from the nucleus of the atom. Within each group of metals reactivity increases as you go down the group. These electrons are called valence electrons. In this experiment, you will combine equal amounts of magnesium and aluminum with hydrochloric acid and compare the … Describe how they All Rights Reserved. How do valence electrons affect reactivity. Generally elements in Groups 1 2 and 13 to 17 tend to react to form a closed shell corresponding to the ##s^2p^6##. 0. 0. It has an ##s^2p^5## electron configuration so it requires only one additional valence electron to form a closed shell.
