Question

Problem 2.1
Calculate the number of protons,
neutrons and electrons in 80 Br.
35​

Answer 1

Answer

Here the atomic mass of Bromine is given 80

and atomic number is 35.

We know,

number of proton=number of electron=atomic number

=>No. of proton=35

=>No. of electron=35

We know,

Atomic Mass= no. of Neutron+ no. of Proton

=>No. of neutron= atomic mass - 35

=>No. of neutron=80-35=45
