(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
A=the mass number (number pf protons and neutrons)
Z=the
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.
