non-metals have between 3 and 8 electrons in the outer shell. You can tell how many they have by looking at which period they're in on the Periodic Table, period 13 elements have 3, period 15 elements have 5 ect.
1 to 3.
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 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.
covalent bonds are when NON METALS share their electrons to get a full outer shell where ionic bonds are when a METAL and a NON METAL "give" each other electrons so they have a full outer shell.
Nitrogen has five electrons in its outer shell and bromine has seven in its outer shell.
No. Argon has eight electrons in its outer shell and magnesium has two electrons in its outer shell.
A chloride anion contains eight outer shell electrons, one more than the seven outer shell electrons found in a chlorine atom.
The outermost shell contains two electrons.

Those electrons are called the valence electrons. They are the ones that can be transferred and form bonds with other atoms.
