Question

yr koi ya wali electronic configuration tu samjado aur ya upar niche signs ka mtlb bhi.​

Answer 1

electronic configuration means the division of electrons in different shell according to its capacity.

aur ye upar niche signs ka mtlb h motion of electrons clockwise and anticlockwise

Answer 2

hey mate your answer of the q. is the atomic number of sodium is 7 then there are 7electrons in there orbitals or shells

there are 4 kind of orbital s, p, d, f
in s→ only two electrons are come so in s only 2electron are come in photo and signs are the spin which is only one spin then it called half spin. and two spin is called full spin. so the p are called is half filled it is on Na

and on Ne the full filled so it is stable

thank you
