Question

no. of neutron in Carbonate ion ?​

Answer 1

↪Solution !!↩

Formula of Carbonate ion = CO3^-2

No. of neutrons in carbonate ion

= mass of ion - no. of protons.

Mass of Carbonate ion

= 12 + 16×3

= 60 amu

No. of protons

= 6 + 8 × 3

= 30

Now , Number of Neutrons

= 60 - 30

= 30.

Answer 2

The Number Of Neutrons In Carbonate Ion Is 44

GIVEN

Carbonate ion - CO₃⁻²

TO FIND

Number of neutrons present in carbonate ion

SOLUTION

We can simply solve the above problem as under-

We know that,

The mass number of ion= Number of proton - Number of neutrons

mass number of carbonate ion = atomic Mass of calcium + atomic mass of oxygen.

The atomic mass of calcium = .40 u

The atomic mass of oxygen atom = 16

The mass number of carbonate ion = 40+ 3(16) = 88

Number of protons in calcium atom= 20

Number of protons in oxygen = 8

Total number of protons in CO₃⁻² = 20 + 3(8) = 44

Number of neutrons in CO₃⁻² = mass number of carbonate- number of protons in carbonate

Number of neutrons in CO₃⁻² = 88-44= 44

Hence the number of neutrons in carbonate ion is 44
