b) With the help of an example, explain the formation of ions on adding acid to water
Answers
Ions are formed when atoms lose or gain electrons in order to fulfill the octet rule and have full outer valence electron shells. When they lose electrons, they become positively charged and are named cations. When they gain electrons, they are negatively charged and are named anions
Explanation:
Ions are formed by the addition of electrons to, or the removal of electrons from, neutral atoms or molecules or other ions; by combination of ions with other particles; or by rupture of a covalent bond between two atoms in such a way that both of the electrons of the bond are left in association with one of the .
An ion is an atom or group of atoms where the number of electrons is not equal to the number of protons. Examples of ions are as follows : H+,Na+,Ca2+F−,O2−
