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.
Answer:
I believe it's A. to reduce air bubbles. Tbh, it's been a while
The the exact mass is 24.740% (according to the internet) but I’d say that it’s 25
This question is very unspecific, but it is probably the Mantle. If that is wrong try Crust.<span />
