1. Atomic Number Of Gallium 70
2. Gallium Atom Model

1. So, the relative atomic mass of gallium is 70, and its atomic number is 31. This means that there are 31 protons in the element. To find out the number of neutrons, you take away the number of.
2. Gallium (Ga) is a silver metal that has the atomic number 31 in the periodic table. It is located in Group 13 of the periodic table. It has the symbol Ga.

What is the electron configuration of the gallium ion?

Diagram of the nuclear composition and electron configuration of an atom of gallium-69 (atomic number: 31), the most common isotope of this element. The nucleus consists of 31 protons (red) and 38 neutrons (blue). 31 electrons (green) bind to the nucleus, successively occupying available electron shells (rings). Is a gallium metal supplier in quantities from 100g to over 1000kgs. We also have stock of high purity gallium and gallium trioxide (Ga 2 O 3 ).

The electron configuration for Gallium, Ga is
#1s^2 2s^2 2p^6 3s^2 3p^6 3d^10 4s^2 4p^1#

Explanation:

Atomic Number Of Gallium 70

Gallium, Ga has 31 protons and 31 electrons. The superscripts represent the electrons present in each region of the periodic table.
The sum of these superscripts should equal the atomic number for a neutral atom. The last electron is in the 4th period, in the p region and the first electron in that region.

The most common electron configuration for the gallium ion, #'Ga'^(3+)# is
#1s^2 2s^2 2p^6 3s^2 3p^6 3d^10# or #['Ar'] 3d^10#.

Explanation:

Gallium is in Group 13. It has 31 electrons.

Its electron configuration is #1s^2 2s^2 2p^6 3s^2 3p^6 3d^10 4s^2 4p#

We form cations by removing electrons first from the outermost #p# orbitals, followed by the #s# orbital and finally the #d# orbitals (if any more electrons need to be removed).

The options for #'Ga'# would be to remove

• the #4p# electron and form #'Ga'^+#
• the #4p# electron and both #4s# electrons and form #'Ga'^(3+)#.

Gallium Atom Model

By far the most common ion of Group 13 metals is +3.

So. the most common gallium ion is #'Ga'^(3+)#, and its electron configuration is #['Ar'] 3d^10#.
