A beta particle is an electron and it has a -1 charge and zero mass.
Beta decay by
emitting an electron is called as β⁻
decay. When this happens, a neutron of the element converts into a proton by
emitting an electron. Hence, the mass of daughter nucleus is same as parent
atom but atomic number/number of protons is higher by 1 than atomic number of
parent atom.
In a β⁻ decay, the symbol is used as ₋₁⁰β or ₋₁⁰e.
-1 is for charge
<span> 0 is for the mass of the particle

Organic elements, depends on the context of the question but I suspect that is the answer. The organic elements are H,O,C,N,P,S
C. Is your answer hope you have a wonderful day
Mass:20g
Mole=20/[2(23)+16]
=0.32 mil
