Question

Chlorine needs one more electron to fill its outer shell. what is the name of the group to which chlorine belongs? responses alkaline earth metal alkaline earth metal alkali metal alkali metal noble gas noble gas halogen

Answer 1

Halogen

Step-by-step explanation:

Chlorine belongs to group 17 on the periodic table, which comprises of nonmetals known as halogens. Halogens have high electronegativities and are highly reactive due to the fact that they have seven valence electrons, and only need one more to gain a stable octet. They are particularly reactive with alkali metals and alkaline earth metals. Alkali metals are found in group 1 of the periodic table and includes some of the most abundant elements such as sodium and potassium. Alkaline earth metals make up group 2 of the periodic table. Both alkali and alkaline earth metals easily lose electrons rather than gain them to fill an octet like the halogens. Noble gases make up group 18 and are also known as inert gases because they tend to be nonreactive as a result of their filled valence shells.
