Question

How many atomic number it would be if there are 4 protons 4 neutrons and 4 electrons and also mass number plz solve it fast​

Answer 1

Answer:

i

Explanation:

No. of Protons + No. of Neutrons = (No. of electrons) = Mass number.

The mass number of He = 4

No.of Protons in He = 2

Using the formula,

No. of Protons + No. of Neutrons = Mass number.

No. of Neutrons = Mass number - No.of Protons

No. of Neutrons = 4-2 = 2

Therefore, No.of Neutrons in Helium atom = 2
