six valence electrons
One.Hydrogen has only 1 electron in total, and it is also a valence electron.
The same number of valence electrons as xenon.
Chemical properties of an element determine by the number of electron
When we say valence electron we mean the number of electron left it the outermost shell of element, valence electron can be positive of negetive. If an element need much electrons to be octet, that means that the element is not reactive than the one who will give out electrons, the the one who can give electrons much are less reactive than the one who can give a litle and the reaction will be normal as it is soppused to be, Eg lithium and berylium. Lithium is more reactive than berylium because lithuin has 1valence electron while berylium has 2....reactivity goes with the action of valence electron in an element
The dots are the valence electrons in the outermost shell of an element. The number of valence electrons are the group number of the element (H=1, O=6, C=4 etc.)

You can determine how many valence electrons an atom has by what family the element of the atom is in. For instance, if the element is in family 8A, the number of valence electrons will be 8. Or, if the element is in family 2A, the number of valence electrons for the atom will be 2. So, whatever number family the atom is in, the number of valence electrons equals that.

Valence electron describes type of element. It either lose or gain electron.
There is one valence electron in lithium, also in every other alkali metal element.

The three factors determine the chemical properties of an element:The number and arrangement of electrons in an atomThe number of valence electronsThe number and arrangement of electrons
By the group number of the A columns.....go apex :D

The velence electron will vary for element to element and can have 1 to 8 valence electrons.
