Question

2. What changes when an ion is made from an atom?

Answer 1

When an ion is formed, the number of protons does not change. By removing an electron from this atom we get a positively charged Na+ ion that has a net charge of +1. Atoms that gain extra electrons become negatively charged. A neutral chlorine atom, for example, contains 17 protons and 17 electrons

Answer 2

Answer:

When ions are made of a single atom, such as Li+1, they are called monatomic ions

Explanation:

Any atom or molecule with a net charge, either positive or negative, is known as an ion. An ion consisting of a single atom is a monoatomic ion; an ion consisting of two or more atoms is referred to as a polyatomic ion.
