Question

How many neutrons does element X have if it’s stormy umber is 33 and it’s mass number is 95?

Answer 1

As we know that element will be represented as

`_(33)^(95)X`

now here we know that

stormy number = 33

this represent the total number of protons in that atom

mass number = 95

this shows the total number of neutrons and protons inside an atom

so it is given as

`95 = N_p + N_n`

`95 = 33 + N_n`

`N_n = 62`

so number of neutrons are 62
