Hybridization of atomic orbitals produces orbital shapes and spatial orientations that correlate to those predicted in VSEPR theory.
<h3>What is VSEPR theory ?</h3>
The number of electron pairs surrounding an individual molecule's core atoms can be used to forecast a molecule's shape using the chemical model known as the valence shell electron pair repulsion hypothesis. The two principal creators of the theory, Ronald Gillespie and Ronald Nyholm, gave it the additional moniker Gillespie-Nyholm theory.
- Hybrid orbital theory explains how these forms are created, while VSEPR theory predicts the shapes of molecules. VSEPR theory's central tenet is that electron pairs—both those in bonds and those that are alone repel one another. "Groups" refers to the electron pairs, both in bonds and lone pairs.

The variation of atomic radii in group 3A,4A,5A and 6A elements is caused by increase in size of the nuclear charge.
Periodic trends are the properties that change down the group and across the period in the periodic table. These properties include; atomic radii, ionic size, electron affinity, electronegativity, ionization energy, etc.
The atomic radii of elements is directly related to the size of the nuclear charge. Across the period, the size of the nuclear charge increases whereas screening remains constant (no new shell is added).
As a result of increased electrostatic pull of the nucleus on the outer electrons, the atomic radii in group 3A,4A,5A and 6A elements decreases progressively across the period.

Explanation:
A low-pressure area, or "low", is a region where the atmospheric pressure at sea level is below that of surrounding locations. Low-pressure systems form under areas of wind divergence that occur in upper levels of the troposphere.
