WebJan 24, 2024 · An element is called a metal if it has one or two or three electrons in its valence shell (except hydrogen and helium, which are non-metals). Metal tends to lose its valence electrons in chemical reactions and complete its octet. Therefore, valency of metallic element \ ( = \) number of electrons in its valence shell. WebOdd-electron molecules represent the first violation to the octet rule. Although they are few, some stable compounds have an odd number of electrons in their valence shells. With an odd number of electrons, at least one atom in the molecule will have to violate the octet rule. Examples of stable odd-electron molecules are NO, NO 2, and ClO 2.
WebNov 4, 2024 · You may assume that the valences of the elements—the number of electrons with which an atom will bond or form—are those that can be derived by looking at the groups (columns) of the periodic table. While these are the most common valences, the real behavior of electrons is less simple. WebMar 19, 2024 · Discuss. Valency or Valence of an element is a measure of an atom’s ability to combine with other atoms to create molecules or chemical compounds. The characteristics of an element that indicate how many more atoms can join one of its atoms in a covalent bond are known as valence, or valency, in chemistry.
