In order to determine the number of electrons in the outer orbit/ valence electrons of a metal, first the total number of electrons needs to be determined. This is done by deriving the atomic number from a Periodic Table. Arrange these in the shell format of 2, 8, 18, 32... The number of electrons in the outermost shell are the valence electrons
This could vary for metal to metal. Some metals have one valence electron (as in alkali metals) and some may have upto 14 (f-block elements).
many atoms cuase its full of energy or mineral
That depends on the atom.

Carbon has four electrons in the outermost energy level, which is energy level two. It needs eight electrons to have this energy level filled.
There are eight electrons in the outermost energy level of a chloride ion.
Three (3) electrons in this energy level.
The outermost energy level of an atom typically has between 1 and 8 electrons.
6
Carbon has four electrons in the outermost energy level, which is energy level two. It needs eight electrons to have this energy level filled.
The chloride ion (Cl-) has 8 electrons on the outermost energy level.
5 electrons
There are eight electrons in the outermost energy level of a chloride ion.
8
Carbon has four electrons in the outermost energy level, which is energy level two. It needs eight electrons to have this energy level filled.
Three (3) electrons in this energy level.
The outermost energy level of an atom typically has between 1 and 8 electrons.
8 electrons
It is the most stable element in the universe and does not need anymore electrons. Its outermost energy level is full.
Helium only needs 2 valence electrons to have a filled outermost energy level.
