Set A (hydrogen, helium, neon) have similar properties because they are all noble gases located in the same group on the Periodic Table, which means they have a full outer electron shell and are stable. The other sets do not have similar properties as they consist of elements from different groups with varying chemical properties.
Potassium Nitrate: Beryllium & Chromium
Emeralds are a variety of the mineral beryl and their green color comes from trace amounts of chromium or vanadium. They also contain other elements such as aluminum and beryllium within their chemical composition. Additionally, emeralds can sometimes have inclusions or imperfections which can affect their clarity and value.
Magnesium (Mg) is the nearest with a mass of 24.3050
BeCr2O7 is the chemical formula for beryllium dichromate, a compound containing beryllium, chromium, and oxygen. It is an orange-red solid that is used in the synthesis of other compounds and as a catalyst in organic reactions.
Chromium (II) Chloride. It's used for the synthesis of other chromium complexes. It dissolves in water to give bright blue solutions that are easily oxidized by ait to give Cr(III) containing products.

The chemical name for CrS is chromium sulfide. It is composed of chromium and sulfur atoms in a 1:1 ratio.
BeS is the chemical formula of beryllium sulfide.
Magnesium, chromium, oxygen it's called magnesium dichromate
Potassium Nitrate: Beryllium & Chromium
There are three elements that make up the compound beryllium chromate: Be = beryllium Cr = chromium O = oxygen
Chromium is associated with iron in chromite.

The atomic number of beryllium is 4. The required element should have the atomic number 4x6=24. The corresponding element is Vanadium (V).Atomic number of Beryllium is 4. Six times of it is 24. Chromium has an atomic number of 24.
Chromium (Cr), which has an atmoic number of 24. Beryllium has an atomic number of 4, so 4*6=24, which is Chromium.
