Answer:
Ionizations of Al atom occurs as
Therefore, ion
is formed from Al atom by loss of 3 electrons. Difference in mass of mole atoms
and 1 mole of ions
= mass of 3 x 6.022 x 1023 electrons
(as mass of an electron )
mole of Al atoms is heavier than 1 mole of ions.
It is because 1 mole of Al atom have electrons
and 1 mole of Al ion have e- = 10 x 6.022 x 1023
electrons
