Question

What are subshells ? How to do electronic configuration of Cr?

Answer 1

first of all we have to know what is shell after that we know aboit sub shell
shell is like a path where electron moves it is also known as orbit all shells are filled with electron in outermost shell cannot ocuppy more than 8 electron
we have to know about sub shell
those shell which is under the outermost shell is known as sub shell

i hope its ryt ans
thanks frnd

Answer 2

the orbitals that present in a shells are known as sub shells.... or the inner shells of the k l m n are known as sub shells.... we can do electronic configuration by following the increasing energy levels given in moeller's chart...... and following aufbau principle, hunds rule,pauli s exclusion principle....
