Question

In a neutral atom that has an atomic mass of 22 and atomic number of 12, how many neutrons does this element have?

Answer 1

Given :

• In a neutral atom that has an atomic mass of 22 and atomic number of 12.

To Find :-

• The number of neutrons .

Solution :-

As we know that,

• n(neutrons) + n(protons) = A
• n(neutrons) + 12 = 2 2
• n(neutrons) = 22-12
• n(neutrons) = 10

Hence the required answer is 10.

Answer 2

Answer:

10 neutrons

Step-by-step explanation:

no.of neutrons = atomic mass - Atomic number

no.of neutrons= 22-12

=10
