Properties

Electron configuration of livermorium

Orbitals fill from the lowest energy upward. Writing that out for livermorium gives 1s² 2s² 2p⁶ 3s² 3p⁶ 3d¹⁰ 4s² 4p⁶ 4d¹⁰ 4f¹⁴ 5s² 5p⁶ 5d¹⁰ 5f¹⁴ 6s² 6p⁶ 6d¹⁰ 7s² 7p⁴, which is 1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p6 4d10 4f14 5s2 5p6 5d10 5f14 6s2 6p6 6d10 7s2 7p4 in plain text.

Everything up to Rn is the same as in that noble gas, so it is usually abbreviated to [Rn] 5f¹⁴ 6d¹⁰ 7s² 7p⁴. The part outside the bracket is what does the chemistry.

Livermorium ion charge

Livermorium commonly forms ions with a charge of -2.

It has 6 valence electrons, so it is 2 short of a full octet and 6 above an empty outer shell. An atom takes whichever route is shorter, which is why the charge comes out as it does.

Common questions

How many valence electrons does livermorium have?

Livermorium has 6 valence electrons. For a main-group element the count is the group number minus 10, and livermorium is in group 16.

What is the electron configuration of livermorium?

1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p6 4d10 4f14 5s2 5p6 5d10 5f14 6s2 6p6 6d10 7s2 7p4, or [Rn] 5f14 6d10 7s2 7p4 written from the previous noble gas. Orbitals fill lowest energy first.

What is the charge of livermorium?

Livermorium commonly forms ions with a charge of -2. With 6 valence electrons it is 2 short of an octet and 6 above an empty shell, so it takes whichever route is shorter.

How many protons, electrons and neutrons does livermorium have?

A neutral livermorium atom has 116 protons and 116 electrons. Its standard atomic weight is 293, so the most common isotope has about 177 neutrons.
