mass no. of A is 6+6 = 12 as it is a carbon( atomic no. of carbon is 6 = no. of protons)
atomic mass of B is also 12 or 14 depending on no. of neutrons in nucleus
charge on A: no charge it is neutral because no. of electron = no. of proton
charge on B = -2 because it has excess of 2 electrons
(A and B) both are the atoms of same element that is carbon as the no. of protons is same
atomic mass of B is also 12 or 14 depending on no. of neutrons in nucleus
charge on A: no charge it is neutral because no. of electron = no. of proton
charge on B = -2 because it has excess of 2 electrons
(A and B) both are the atoms of same element that is carbon as the no. of protons is same
as proton is having positive charge
and electron is having negative charge
so u can compare the no. of electrons and protons and identify the charge
on the species
now see A has 6 electrons and 8 protons
so u can compare the no. of electrons and protons
u will find that A has excess of two protons so it has a positive charge
hope i have cleared ur doubt
is ur doubt cleared???
The 3rd answer is isotopes ...

Answer:
Explanation:
mass no.=no. of protons+no. of protons
FOR A
mass no.= no. of protons+no. of neutrons
=6+6
=12
FOR B
mass no.=no. of protons +no. of neutrons
=6+8
=14
thus, mass no. of A=12
mass no. of B=14
