Question

What is the most reactive element in group $16.$

Answer 1

We know that the oxygen differs from other elements of the group $16$ due to its high electronegative character, small size and high ionization enthalpy. Hydride of oxygen means water molecules form hydrogen bonds due to the high electronegative character of oxygen.

Complete answer:
Most of the elements of the p block form covalent compounds although some elements form ionic compounds such as halogens and coordination compounds as well. The P-block contains elements which are either metals, nonmetals or metalloids. P-block elements include the group of halogens and inert gases. First member of each family of the p-block elements is given below in the table with their general electronic configuration and oxidation states. p-block has the most electronegative element which is fluorine. Elements of p-block generally form acidic oxides.
Oxygen is the periodic table’s most reactive portion. In the periodic table, it is the second most electronegative product, making it the group’s most reactive. The oxygen group is sometimes called the group $16$ elements of the periodic table. Nonmetals are the first three elements-oxygen (O), Sulphur (S), and selenium (Se). Tellurium (Te) a metalloid, and polonium (Po) metal, are then pursued. They have six valence electrons in all group $16$ elements as well as are very reactive. At room temperature, oxygen is a gas and the other elements in the group are solids.

Note:
Remember that the oxide is a chemical compound that contains at least one oxygen atom and one other element. Dianion of oxygen is also called oxide. All oxides compounds contain at least one dianion of oxygen. Oxides are generally binary compounds composed of oxygen and another element.
