Write the electronic configuration of the elements given below and predict their period, group, block and also name the class, i.e., representative, transition etc. to which they belong.
`""_(61)C`

Explanation

`""_(61)C=1s^(2) 2s^(2) 2p^(6) 3s^(2) 3p^(6) 3d^(10) 4s^(2) 4p^(6) 4d^(10) 4f^(5) 5s^(2) 5p^(6) 6s^(2)`
Valence shell =6th, period = 6
Last electron (61st) in 4f sub-shell, block = f
Group = 3 all f-block elements belong to 3rd group
Class= Inner transition element, f-block element
