Magnesium. The complete electron configuration is: 1s2 2s2 2p6 3s2 The complete electron arrangement is: 2e, 8e, 2e
Magnesium is a metal element. Atomic number of it is12.
Magnesium has a total of 12 electrons. The electron configuration would be 1s2 2s2 2p6 3s2. Therefore, 2 electrons in it's outer shell.
It depends, most atoms need 8 total valence electrons in their outer shell (some need 2). So subtract the number they have (determined by the group that the element is in) from 8 and that is how many they need to fill their outer shell!
244 An interesting answer...I would have thought that they all have 2 electrons in the outer shell in their ground state.
Tellurium has a total of 52 electrons in its standard state.
The number of valence electrons is dependent on which group of the periodic table the element is in.Since Argon is in group 8, it has a total of 8valence electrons.

It is Oxygen. Because Oxygen has the atomic no. - 8. Which means that 2 electrons can accommodate in the inner shell and the rest of the electrons (6 electrons) are in the out shell.
it is related to the number of electrons that are in in the outer shell, and the total number of electrons

This is radon, it has a full outer shell of electrons, so it is technically non reactive
Only two electrons.
Tellurium has a total of 52 electrons in its standard state.
Two. An inner shell contains 2 electrons; and an outer shell contains 2 electrons on its near side and 4 more electrons on its outer side. Total of 8 electrons.
The number of valence electrons is dependent on which group of the periodic table the element is in.Since Argon is in group 8, it has a total of 8valence electrons.
The outer valence shell of a sulfur atom contains a total of 6 electrons: two 3s electrons and four 3p electrons.
There is a total of 8 electrons that are needed to fill outer shell of most atoms. An atom is the smallest unit of matter.
