Covalent molecules are the molecules in which the atoms are linked by covalent bonds. The electrons involved in the formation of a covalent bond are known as shared pair or bond pair of electrons.

The three-dimensional arrangement of the atoms of a molecule in space is known its molecular structure or geometry.

Given molecule: XY₂, having two lone pairs around the central atom X.

Since the molecule XY₂ has two lone pairs and two bond pairs of electrons. Therefore according to the VSEPR theory, the given molecule has a bent molecular geometry with 109° bond angle.

Moseley made revisions to the periodic table that resolved some of the problems with Mendeleev’s version. Which of these was a r

olga55 [171]

The result of Moseley's revisions were that the elements were arranged in atomic number order rather than atomic mass order.
