The d-block elements are called transition metals and have valence electrons in d orbital’s.
“Transition metal” as any element in the d-block of the periodic table, which includes groups 3 to 12 on the periodic table.
In actual practice, the f-block lanthanide and actinide series are also considered transition metals and are called “inner transition metals”.

Neutral

The pH scale measures how acidic or basic a substance is. The pH scale ranges from 0 to 14.

A pH value is a number from 1 to 14, with 7 as the middle (neutral) point. Values below 7 indicate acidity which increases as the number decreases, 1 being the most acidic.

Hydrogen has three naturally occurring isotopes: 1H (protium), 2H (deuterium), and 3H (tritium). Other highly unstable nuclei (4H to 7H) have been synthesized in the laboratory, but do not occur in nature. The most stable radioisotope of hydrogen is tritium, with a half-life of 12.32 years.

Beryllium Sulphate is less soluble in water due to high inflammable energy.

The energy level of Beryllium Sulphate is so much that it cannot overcome the lattice energy

Low energy of dissociation is another reason behind Beryllium Sulphate’s less solubility . Moreover Beryllium Sulphate is having ionic bond so the force of attraction between the molecules is very high and thus is less soluble in water.

Bleaching Powder:Bleaching powder is calcium oxychloride. The chemical formula of bleaching powder is CaOCl2. It is also called chloride of lime.
