Rules for filling electrons in shells

No of electrons in KLMN shell.

Name the rules that one must obey while filling electrons in various orbitals.

Filling of electrons in the orbitals on a ground state atom is governed by three rules. a) Which are the three rules?

Filling of electrons in the orbitals on a ground state atom is governed by three rules. b) State any one of them.

Which element is having 5 electrons in valence shell?

Which elements are having 2electrons in valencesub-shell?

Which elements contains 5 electrons in the outermost shell?

State the principles /rules for filling of orbitals in atoms.

The number of spectral lines that can be possible when electrons in 7^(th) shell in different hydrogen atoms return to the 2^(nd) shell

Assess the properties of elements and classify it as p and d block elements. • form coloured compounds • includes metals and non-mentals. •show various oxidation states. • The last electrons are filled in the outermost shell. • show similar properties, in periods. •The last electrons are filled in the shell preceding the outermost shell. •Only metals are included.
