Question

atomic number of Aluminium is 13 and mass number is 27 calculate the number of electron proton neutron in this atom

Answer 1

Heya user ,
Here is your answer !!

Atomic number = 13
Atomic Mass = 27 .

So ,
no. of electrons = 13
no. of protons = 13
no. of neutrons = 27 - 13 = 14

Hope it helps you !!

Answer 2

it is given that the atomic number of Aluminium is 13 and mass number is 27 electrons can be easily calculated by understanding that the atomic number and electron number is surely the same the electrons present in the Aluminium is 13 then we also know that electrons are equals two protons so therefore protons are also equals to 13 find out the number of neutrons in this atom we we should subtract the mass number and atomic number from that we understand that 27 - 13 rupees equals to 14
