Question

the atomic number of an element is 6. its mass number is 12. find the number of proton and neutron in it. identify the element

Answer 1

Atomic number = number of protons

So number of protons = 6

Number of neutrons = atomic mass number - number of protons

= 12 - 6 = 6

Number of neutrons = 6

Answer 2

Atomic no = no of protons

So no of protons = 6

No of proton = atomic mass no - noof proton

12-6 = 6

No of neutron = 6

Hope it helps
