The Halogens.
Halogens
what is the mass of a protein
This family is the halogen group: F, Cl, Br, I, At, Uus.
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.
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.
It is not true; many metals are very reactive and several nonmetals are nonreactive.
Fluorine, chlorine, bromine, and iodine are some examples of reactive nonmetals. They are located in Group 17 (halogens) on the periodic table and tend to readily gain electrons to achieve a stable electron configuration.
The most reactive nonmetals are located in top most right section of the Periodic Table, excluding group 18 (has no reactivity).
A very reactive group of metals is the alkali metals, such as sodium and potassium, while a very reactive group of nonmetals is the halogens, like chlorine and fluorine. Alkali metals have a single electron in their outermost shell, making them eager to lose that electron and achieve a stable electronic configuration. Halogens, on the other hand, have seven electrons in their outer shell and readily gain an electron to complete their octet, leading to high reactivity. This tendency to either lose or gain electrons drives their chemical reactivity.
Group 17 elements, 'Halogens', have seven electrons in their valence shell and show the valency of 1. 4 of the 5 elements in that group are non metals including fluorine, which is the strongest.
