Question

The behavior of an atom depends on the __________.

A) valence electrons in the innermost electron shell

B) the number of extra neutrons in the nucleus

C) the electronegativity of the particular atom

D) the atomic mass of the atom

E) valence electrons in the outermost electron shell

Answer 1

The behavior of an atom depends on the valence electrons in the outermost electron shell.

Step-by-step explanation:

The behavior of an atom depends on the valence electrons in the outermost electron shell. The valence shell is an atom's outermost electron shell, and if it is not full, the atom is reactive and will tend to react with other atoms to make its valence shell full.
