Answer : Electrically charged atoms or combinations of atoms are called ions

Explanation :

An ion is formed when an atom loses or gains electron.

An atom is electrically neutral because it contains equal number of protons and electrons.

But when an electron is lost from the atom, it creates an imbalance of protons and electrons. We have more protons than electrons and as a result the atom becomes positively charged and known as "Cation"

On the other hand, when an electron is gained, we have more electrons than protons. Therefore the atom becomes negatively charged which is known as "Anion"

In general, these electrically charged species are known as "ions".

a  solution  is always transparent, light passes through with no scattering from solute particles which are molecule in size. the  solution  is homogeneous and does not settle out. a colloid is intermediate between asolution  and a  suspension. while asuspension  will separate out a colloid will not.
