Question

Calculate the number of protons and atomic number of an element with mass number 56 and 30 number of neutrons.​

Answer 1

Answer:

26

Explanation:

We know that in an atom

$number \: of \: proton \: + number \: of \: neutron \: = mass \: number$

From the formula we can get

Number of proton = 56 - 30 = 26

Now,

Number of proton = Atomic number.

So,

Atomic number is also 26.
