Question

Rubidium forms the positive ion Rb+. Does this ion have more or fewer electrons than the neutral atom?

Answer 1

Answer:

The ion has fewer electrons

Explanation:

As Rubidium forms a positive ion Rb⁺ the number of electrons becomes fewer for the atom.

• A positive charge on an ion indicates that the number of protons for the atom is greater than the number of electrons.
• This leaves a net positive charge on the atom.
• For a negatively charged ion, the number of electrons is more than the number of protons because they have gained additional electrons.
• In a neutral atom, the number of protons and electrons are the same.
