Question

A particle P has 18 electrons, 20 neutrons and 19 protons. This particle must be (a) a molecule
(b) a binary compound
(c) an anion
(d) a cation

Answer 1

The particle P should be a cation.

Explanation:

• Ions are of two kinds: cations and anions. Cations are the type of ions that have a positive charge. From the above information, it is understood that one electron is lost from the particle. So, the particle P should be a cation.
• Several names can be provided to the cations with different charges. For instance, a cation with positive charge 3 is called a trication. A cation with a positive charge of 2 is called a dication.
