Write the distribution of electrons in carbon and sodium atoms.

Answer»

Solution :ATOMIC number of carbon is 6.
`therefore` number of protons= 6
Number of protons = number of ELECTRONS. So, it has 6 electrons.
K shell - 2 electrons
L shell - 4 electrons
atomic number of sodium is 11 .
`therefore ` number of protons = 11
number of protons = number of electrons
So, it has 11 electrons.
K shell - 2 electrons
L shell - 8 electrons
M shell - 1 electron
