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.
Metals generally have 1 to 3 electrons in their outer shell. These outer shell electrons are loosely held and can be easily lost, which is why metals tend to form positive ions in chemical reactions.
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.
Nitrogen has five electrons in its outer shell and bromine has seven in its 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.
Boron has three electrons in its outer shell
No. Argon has eight electrons in its outer shell and magnesium has two electrons in its outer shell.
Metals generally have 1 to 3 electrons in their outer shell. These outer shell electrons are loosely held and can be easily lost, which is why metals tend to form positive ions in chemical reactions.
The outermost shell contains two electrons.

A chloride anion contains eight outer shell electrons, one more than the seven outer shell electrons found in a chlorine atom.
Inner shell electrons are electrons that are located closer to the nucleus of an atom, shielded by outer electron shells. They have lower energy levels compared to outer shell electrons and are generally not involved in chemical reactions.
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.
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.
