halogen
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).
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.
Halogen
The very reactive elements are typically found in Group 1 (alkali metals) and Group 17 (halogens) of the periodic table. Alkali metals tend to react violently with water, while halogens are known for their high reactivity and tendency to form salts with metals.
