The number of nuclear protons are the number of positively charged particles contained in atomic nuclei.

Z

, the atomic number,

=

6

for carbon, and

8

for oxygen. In the carbonate atom nuclei there are therefore 30 positively charged protons.

So how many electrons on carbonate? There are 6 from carbon, 24 from oxygen, PLUS 2 extra negatively charged particles from the formal charge on the anion. 32 electronic charges (

32

) versus 30 protonic charges (

+

30

). There is a formal charge of

2

on the carbonate anions, the which we conceive to be on the oxygen atoms (the doubly bound oxygen is neutral, whereas each of the singly bound oxygen atoms bears a negative charge), to give

O

=

C

(

O

)

2

Of course this assignment of charge is a formalism; and we would distribute the charge over the oxygen centres by resonance.

Answer:

Number of electrons = 32

Number of protons = 30

Number of neutrons = 30

Explanation:

It is given ;

Carbonate ion : CO₃²⁻

So it has Carbon and Oxygen

Therefore, for Carbon :

Atomic number of Carbon  = 6

Number of electrons = 6

Number of protons = 6

and for oxygen :

Atomic number of Oxygen = 8

Number of electrons = 8

Number of protons = 8

Hence, Number of electrons in CO₃²⁻ = 6 + (3 x 8) + 2 = 32 electrons

Number of protons in CO₃²⁻ = 6 + (3 x 8) = 30 protons

and we know that :

Mass  number = number of neutrons + number of protons

So, (1 x 12) + (3 x 16) = Number of neutrons + 30

or, number of neutrons = 60 - 30 = 30
