poor metals have four, five, six..... electrons in its outermost shells these poor metals are also known as non-metals.
Alkaline earth metals have 2 electrons in their outer shell.
Alkali metals have 1 electron in their 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.
Few, one to three.
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.
Nitrogen has five electrons in its outer shell and bromine has seven in its outer shell.
Vanadium has on the outer shell two electrons.
Boron has three electrons in its outer shell
Calcium has two electrons in the outer shell.
There is one electron on cobalts 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)
4V V-Valence Electrons Valence Electrons-Last electron (which is on the outer shell)
