Answer:
Atomic no.= 82
Mass no.= 207
we know,
no.of electrons=no of protons= no of Neutrons
so
No of neutron= Mass no. - Atomic No.
= 207 - 82
= 125
hence no of neutrons = 125
Hope it helps

Answer:
The number of neutrons in Lead is 125
Explanation:
Atomic Number of Lead is 82 and its mass number or atomic mass is 207. we can determne the number of number of neutrons by the formula
no. of neutrons = mass no. - atomic no.
no. of neutrons = 207 - 82 = 125
Hence number of neutrons in in lead is 125
