halogens
No, the lithium family is not a reactive group of mostly nonmetals with 7 valence electrons. The lithium family, also known as the alkali metals group, includes lithium, sodium, potassium, rubidium, cesium, and francium. These elements are metals and have 1 valence electron.
The element with one valence electron and is very reactive is sodium. Sodium is a member of the alkali metal group and readily gives up its outer electron to form positive ions in chemical reactions.
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 atoms in column 7 of the periodic table, also known as Group 17 or the halogens, all have seven valence electrons. These atoms are highly reactive nonmetals that tend to gain one electron to achieve a stable electron configuration. The elements in this group include fluorine, chlorine, bromine, iodine, and astatine.
because to be stable they need 8 atoms in outer energy level halogens need one so are highly reactive. alkali need 7 so are highly reactive( not as highly as halogens)
Halogens
because of having only one electron in valence shell

They are basically called halogens.
reactive parts of an electron?
Highly reactive metals with one valence electron are known as Alkali metals.
Halogens family have 7 valence electrons.They belongs to family 17 on the periodic table.They are highly reactive as they accept electron readily to complete their shell.
Yes. This is due to the fact that their valence shells are adding electrons, coming closer to having an octet. The halogens in group 17/VIIA are the most reactive nonmetals because they have seven valence electrons and readily react in order gain the eighth valence electron, which gives them an octet like the nearest noble gas. It takes much less energy to gain one electron or share one electron, than it does to gain or share two or more electrons.
Highly reactive metals with one valence electron are known as Alkali metals.

The Nobel gasses. Generally inert.
