one valence electron
Depending on how many valence electrons in the element has, The other element could take away a valence electron to make eight
== == When metals react with other elements, the atoms of the metals give up their valence electrons.
Elements in the same group have the same number of valence electrons. These are the outer-shell electrons that react with other elements.
Under normal conditions Helium will not react with anything because it has a complete outer electron shell.
The Noble Gases are so-called because they do not readily react chemically with anything, due to their valence electron shells being filled with 8 electrons. The exception, of course, is helium, He, which only has 2.

The valence of an element in a chemical compound can be determined by looking at the group number of the element on the periodic table. The group number indicates the number of valence electrons an element has. For example, elements in group 1 have a valence of 1, elements in group 2 have a valence of 2, and so on. The valence of an element is important in understanding how it will react with other elements to form compounds.
No. Chlorine is more reactive than silicon. This is because Chlorine has 7 valence electrons; nearly a full outer shell, while silicon has only 4 valence electrons. An element needs 8 valence electrons to react, and Chlorine only needs one more valence electron before it can react, unlike Silicon, which needs 4.
There is no halogen that will become anionic. All of the valence electrons in halogens are filled, thus halogens will not react with any other compound or element. Bromine is an element that will form and anion with 36 electrons.

the element with seven valence electrons will be more reactive. The reason for this is that elements want to always want to have a full valence shell (they always want 8, like a noble gas). The element with eight valence electron is happy with its full shell and will not want to get rid of any electrons.
