Oh, dude, that would be helium! It's like the cool kid at the noble gas party with its full octet of electrons, just chillin' in the corner. So, yeah, helium is the first member of the noble gas family with that full octet vibe.
Halogen family members, or elements in group 17, have 7 valence electrons.
The nitrogen family, also known as group 15, consists of nitrogen, phosphorus, arsenic, antimony, and bismuth. These elements all have five valence electrons in their outermost energy level, which gives them similar chemical properties such as forming covalent compounds and typically gaining three electrons to achieve a full outer shell.
The neon family, also known as Group 18 on the periodic table, contains elements with 8 valence electrons. This includes elements such as helium, neon, argon, krypton, xenon, and radon. Valence electrons are the electrons in the outermost energy level of an atom.
Each period has one more energy level than the last: lets look at group 1 the alkaline metals as an example H - 1 - one energy level Li - 2,1 - two energy levels Na - 2, 8, 1 - three energy levels K - 2, 8, 8, 1 - four energy levels ect
The family of elements with two electrons in its outer energy level is the alkaline earth metals. This group includes elements like beryllium, magnesium, calcium, strontium, and barium. These elements are highly reactive and tend to form 2+ cations by losing their two outer electrons.
Neon
Yes, it does, this is because its outermost shell consists of 7 electrons.

they all have a differnet number of electrons, but all have a charge of 1-
no!
This is the alkali metals family; the ionization energy is lower for these chemical elements.

Fluorine... it has seven valence electrons and really wants to achieve noble gas configuration (8 out of 8 possible valance electrons). It already has seven and since it is so close to eight, it is very attached to them. It refuses to give them up easily. The more an element "wants" it's electrons the higher ionization energy it will have. http://www.800mainstreet.com/4/0004-002-Periodic.html
