Question

an atom x that has 12 protons and 12 electrons, it donated two electrons to form an ion.
a) what will be the charge on the ion
b) which kind of ion will be formed
c) what will be the no. of proton and electron in the ion

Answer 1

Explanation:

a. The element belongs to the group second, therefore it will have 2+ charge.

b. The ion will be cations.

c. number of proton will be 12 and 10 electron.

Answer 2

$\bf\huge\underline{\underline{ Given :- }}$

• an atom has 12 protons and 12 electrons

• it donated 2 electrons to form an ion

$\bf\huge\underline{\underline{ To \: Find:- }}$

• charge of ion

• kind of ion formed

• no. of proton and electron in that ion

$\bf\huge\underline{\underline{ Answer :- }}$

• Let the atom be X

• $\bf\red{ _{12}X }$ will be the neutral atom

since it donated two electron , charge = +2

• It is a cation [ +ve ions are cations ]

no. of protons = 12

no. of electrons = 10
