Question

Number of Neutron in 6 atom of He:

​

Answer 1

Answer:

6 atoms of Helium-4, the standard isotope of helium, it has 12 neutrons.

To find this, you need to know how many neutrons are in 1 atom of Helium, and to do that, you need to know the atomic weight of Helium-4, and the atomic number.

The weight is 4 (hence the name Helium-4), and the atomic number is 2 (after Hydrogen and before Lithium).

All you need to do is subtract the atomic number

Answer 2
