The parent element 247 95 am decays by beta decay which daughter element will formn

Atomic mass of the parent element =247,
atomic number of the parent element = 95

In the process of β-decay electron leaves the nucleus, so instead of one neutron we get one proton.

Mass of proton≈mass of neutron,
so atomic mass will not change.

Charge of proton =+1, and charge of neutron = 0.
So, we will get atomic number increased by one.

New element (daughter) will have 
atomic mass = 247, 
and atomic number= 95+1=96

Number 95 - Am (parent),
number 96 - Cm(daughter),

So, from Am-247 we will get Cm-247.
