The Halogens.
there are 7 electrons in the outer energy level of group 17 elements
The number of electrons are different from one to another, however all of them have seven electrons in the valence shell.
The atoms of both elements have seven valence electrons and a strong tendency to abstract, from a less electronegative atom, an electron to complete their valence shells and thereby become an anion.
None. Neon is a noble gas, a category of elements that exist in nature as inert gasses. In special situations, neon can be made to react with other elements, but in ordinary conditions, neon is inert, which just means non-reactive. It's outer orbit is full--it doesn't want to give up the electrons it has, or to take any more.
The element chlorine has seven electrons in its valence shell.
The halogens, or group 17
Any element in the halogen group will have seven valence electrons. These elements include fluorine, chlorine, bromine, iodine, and astatine.
Group 1 have one valence electron. The elements in Group 2 have two. The elements in Group 17 have seven valence electrons, and Group 18 elements have eight. Because the valence electrons within a family are the same, the elements in that group have similar properties.

All halogens (fluorine, chlorine, bromine, iodine and astatine) have 7 valence electrons.
The group of the element indicates the amount of valence electrons. For example, the alkali metals have one valence electron and is in group one whilst the halogens have seven valence electrons and are in group seven.
The halogens have seven valence electrons. The halogens are F, Cl, Br, I, and At. Fluorine
halogens such as flourine, chlorine, bromine..
halogens or group 17
The most reactive elements have either 1 valence electron or 7 valence electrons
halogens (group 17 elements)
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.
