WebCount the number of lone pairs + the number of atoms that are directly attached to the central atom. This is the steric number (SN) of the central atom. SN = 4 → sp³. SN = 3 → sp². SN = 2 → sp. For example, the O atom in water (H₂O) has 2 lone pairs and 2 directly attached atoms. ∴ SN = 2 + 2 = 4, and hybridization is sp³.

WebAn s orbital is spherically symmetric around the nucleus of the atom, like a hollow ball made of rather fluffy material with the nucleus at its centre. As the energy levels increase, the electrons are located further from the nucleus, so the orbitals get bigger. The order of size is 1s < 2s < 3s < …, as shown below.

WebMilankovitch cycles explain the creation of the ice ages. Think about Eccentricity. In order for the ice sheets to grow enough to create an ice age, you need "summer" to happen when the earth is furthest away from the sun (cooler summers, little ice melt) and "winter" to appear when the earth is nearest the sun (lots of fluffy snow to build up).
