Electrons are particles that have an electric or negative charge. You may know this word because you have heard them with two other particles. Those are the protons which have a positive charge and neutron which has a neutral charge. For specific actions to take place, there should be a certain amount of electrons.

Isoelectronic is a term that is used in science to mean that more than two chemical items come together, but this item has different atoms. However, they have the same amount of electrons. The three species of is electronics that have the same number of particles would be S2, K+, and CA2. K stands for potassium and is located on the periodic table. CA stands for calcium.
