Question

the nucleus of a neutral atom has 10 peotons and 10 neutrons. the number of electrons present in it is​

Answer 1

As we know,

Atomic no. of an atom is total no. of the proton (p) present in the nucleus of atom and every neutral atom has the same no. of proton and electron.

The mass number of an atom is the total number of neutron and proton (n+p) present in the nucleus of an atom.

the number of protons 10 and 10 neutrons.

So, Atomic mass number = p+n = 10+10 = 20.
