What is the oxidation number for gallium?

Answer 1

Germanium has 32 electrons.

They are arranged in 4 shells ; 2,8,18,4.

The inner most shell contains 2 electrons and the outermost shell contains 4 electrons.

The element Germanium is in Group 4 (Carbon group)

It is in Period 4.

Its electron configuration is ; [Ar] 3d(10), 4s(2) , 4p(2)

The [Ar] may be replaced by the FULL electrons configuration.

1s2, 2s2, 2p6, 3s2, 3p6, 3d10, 4s2,4p2.

Hope that helps!!!!!

Answer 2

1s2 2s2 2p6 3s2 3p6 4s2 3d8 5s2 4p2

Edit by Dr.J. How can this have 5s2 electrons? This configuration is incorrect. Germanium is a p-block element and so has 4p valence electrons, not 5s.

Answer 3

• 2.01 on the Pauling scale.
• 2.62 on the Sanderson scale.
• 2.02 on the Allred-Rochow scale.
• 2.33 on the Mulliken-Jaffe scale.
• 1.994 on the Allen scale.

Answer 4

Ar 3d10 4s2 4p2 or written out it is 1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p2
