1 to 3.
Most metals and non-metals bond together to get eight electrons in their outer occupied shell. This is what is referred to as ionic bonding.

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.
NO. Nonmetals tend to GAIN electrons to complete their outer shell. By gaining electrons, they become a negatively charged species, which is what an anion is. Metals tend to LOSE electrons to end up with a full outer shell; in losing electrons, they develop a positive charge (become cations).
There are two electrons on the outer shell which means they are pretty reactive. (make bonding easier)

1 electron.
metals generally acts as reductants because a relatively small amount of energy is needed to remove the small number of outer-shell electrons in metals.
Few, one to three.
The outermost most weakly bound electrons are those that form bonds. These are those generally in the outermost shell. However in say transition metals the electrons in the outer s orbital and the d orbital of the shell below are involved.
Thrse electrons are involved in chemical reactions.
the alkali metals have 1 electron in their outer most shell. in order to obtain a full outer shell they have to lose this electron. so when they react with another metal they lose this electron and the outer most shell.
poor metals have four, five, six..... electrons in its outermost shells these poor metals are also known as non-metals.
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.
Alkali metals are from Group 1 of the Periodic table and have a single electron in their outer shell. Alkaline-Earth metals are in group 2 of the periodic table and have 2 electrons in their outer shell.
Metals tend to lose electrons to form positive ions because, for metals to gain a full outer shell, they need to lose electrons.
