Answer 2

To count  number of atoms, molecules,  electrons, protons and ions etc. Which term is used.

Explanation:

To count number of atoms, molecules, electrons, protons or ions, we use the term Moles.

Meaning of term Mole in general is a pile or heap.

Mole in chemistry is the unit of measurement according to International Unit of Standards.

one mole of a substance is Avogadro' number.

$1 mole= 6.02214\times 10^{23}$

When we say one mole of any compound, for example, one mole water, it means:

there are $6.02214\times 10^{23}$ molecules of water.

In one mole of NaCl, there are $6.02214\times 10^{23}$ cations of sodium and $6.02214\times 10^{23}$  anions of chlorine.
