(a) Interpretation: The symbol for each atom/ion given in the A Z X format should be determined. Concept Introduction: The atomic symbol (composition of sub atomic particles in a given atom) can be denoted as A Z X where the symbols have the following meaning. X = the symbol of the element A=the mass number (number pf protons and neutrons) Z=the atomic number (number of protons) Also, A=Z + Number of neutrons Therefore, Number of neutrons=A-Z In an ion number of electrons is not equal to number of protons. In a cation number of electrons< no of protons while in an anion number of electrons> no of protons.

Concept Introduction:
The atomic symbol (composition of sub atomic particles in a given atom) can be denoted as A Z X where the symbols have the following meaning.
X = the symbol of the element
A=the mass number (number pf protons and neutrons)
Z=the atomic number (number of protons)
Also, A=Z + Number of neutrons
Therefore, Number of neutrons=A-Z
In an ion number of electrons is not equal to number of protons. In a cation number of electrons< no of protons while in an anion number of electrons> no of protons.
