Answer:

The answer would be A. the number of electrons in the outermost electron shell.

Explanation:

These are called valence electrons which are transferred, shared, and rearranged by creating covalent bonds producing new substances.

The type of chemical reaction an atom chooses is determined by the number of the outermost electrons in the outermost shell of an atom.

  1. The reactivity of an atom is determined by the number of electrons in the outermost shell of the particular atom.
  2. The number of electrons is used to determine the type of bond formed by that atom in a chemical reaction.
  3. The outermost shell of the atom is called the valence shell and the number of outermost electrons is thus called the valence electrons.

About the importance of electrons the below points should be noted;

  • The electron is the major constituent of an atom which determines the reactivity of an atom.
  • The outermost electron is more used for any reaction to occur than the innermost electrons

Therefore the answer is the number of electrons in the outermost electron shell.
