1 electron.
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.
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.
Seven , outer shell electrons or valence electrons increase as you move from left to right on the periodic table not including the transition metals which vary, they start with 1 valence in the alkali earth metals , and finish with 8 valence electrons on the noble gasses (group 18)
No. Argon has eight electrons in its outer shell and magnesium has two electrons in its outer shell.
Vanadium has on the outer shell two electrons.
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.

1 to 3.
Few, one to three.
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.
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.
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)
