The outermost shell contains two electrons.
No. Argon has eight electrons in its outer shell and magnesium has two electrons in its outer shell.
Potassium (K) has one electron in its outer shell, which makes it a Group 1 alkali metal. Calcium (Ca), on the other hand, has two electrons in its outer shell, placing it in Group 2 as an alkaline earth metal. This difference in the number of outer electrons contributes to their distinct chemical properties.
Alkaline earth metals have 2 electrons in their outer shell.
Copper is an example of a metal that can use its inner shell before outer shell electrons to bond. It has a configuration of 3d104s1, and the 4s electrons are used before the 3d electrons in bonding reactions.
Magnesium has a total of 12 electrons. The electron configuration would be 1s2 2s2 2p6 3s2. Therefore, 2 electrons in it's outer shell.
A chloride anion contains eight outer shell electrons, one more than the seven outer shell electrons found in a chlorine atom.
Nitrogen has five electrons in its outer shell and bromine has seven in its outer shell.
Copper is a non metal element. There are 29 electrons in a single atom.
It would be a non-metal and a halogen. Group 18 or the noble gases, all have 8 electrons in their outer shell. Therefore, the group before it would have seven electrons in the outer shell. This group is made up of all non-metals.

Alkali earth metals have 2 electrons in their outer energy level. This outer level is known as the valence shell, and having 2 electrons makes these metals highly reactive and likely to form ionic bonds to achieve a full outer shell of 8 electrons.
