Match the following families on the periodic table with the description. brainliest for the first right answer!

Explanation:

Elements of group 1 are known as alkali metals and these include elements like lithium, sodium, potassium, rubidium, cesium, and francium.

Halogens are the elements of group 17 and each element of this group contains 7 valence electrons. For example, fluorine, chlorine, bromine, and iodine are all halogens.

Group 3-12 contains elements like scandium, titanium, vanadium, chromium etc. All these elements are also known as transition elements.

Noble gases are the gases that belong to group 18. Elements of this group are helium, neon, argon, krypton, xenon etc. All the gases are compressible in nature as they have large gaps between each molecule. Hence, they are easily compressible.

Elements of group 2, that is, alkaline earth metals contain two valence electrons. Elements of this group are beryllium, calcium, magnesium, strontium etc.

Thus, given families are matched as follows.
