Question

The atomic number of an element is 12 and it's mass number is 24. The number of electrons,protons and neutrons respectively will be​

Answer 1

Answer:

Therefore, Number of electrons and number of protons is 12. Number of neutrons = 24 - 12 = 12. Hence, the correct order representing the number of electrons, protons and neutrons respectively in this atom is 12, 12, 12.

Answer 2

Answer:

12, 12 and 12

Explanation:

Q.

The atomic number of an element is 12 and it's mass number is 24. The number of electrons,protons and neutrons respectively will be

Ans.

The atomic number = proton number = Electron number = 12

Mass number = Atomic number + Neutron

So neutron = Mass number - Atomic number

= 24 - 12

= 12

Hence number of Electrons, protons and neutrons is 12.

More to know :-

• Atomic number = Proton Number = Electron number
• Mass number = Atomic number + Neutron
