Chapter 6, Problem 15E

Interpretation Introduction

Interpretation:

Monatomic anions formation from atoms, in terms of protons and electrons is to be explained.

Concept introduction:

Atomic number of an atom is equal to the number of protons in its nucleus and this is equal to the number of electrons. In other words, the number of protons and the number of electrons will be the same for a neutral atom and results in no net charge on the atom (i.e., positive or negative). The atom gains a net electrical charge with respect to the number of electrons accepted or released by the atom. Usually, the atom acquires a positive charge when an electron is removed, and the atom acquires a negative charge when an electron is added in its outer shell. The positively charged atom is called as ‘cation’ and the negatively charge atom is denoted as ‘anion’.
