Question

An atom X that has 12 protons and 12 electrons, loses two electrons to
form an ion.What will be charge of the ion? What will be the number of
protons and electrons in the ion?

Answer 1

SOLUTIONS

Since, the atom looses two electron , net electron = 10.

number of proton = 12.

Hence, net charge = 12 - 10 = +2.

So,

net charge = +2

number of electron = 10.

number of proton = 12.

Answer 2

Element X :

==> 12p + 12e

Atomic Num. = 12

Ion = 12 - 2 electrons ( positive charge of 2 )

$X^{+2}$

Num. of electrons in the ion = 10e

Num. of protons in the ion = 12p
