According to VSEPR theory, the terminal atom locations (Xs in Figure \(\PageIndex{7}\)) are equivalent within the linear, trigonal planar, and tetrahedral electron-pair geometries (the first three rows of the table).

Water (H 2 O) - Water has two hydrogen atoms bonded to oxygen and also 2 lone pairs, so its steric number is 4.; Ammonia (NH 3) - Ammonia also has a steric number of 4 because it has 3 hydrogen atoms bonded to nitrogen and 1 lone electron pair. InChI=1S/H3N/h1H3/p+1
The steric number of a molecule is used in VSEPR (valence shell electron pair repulsion) theory to determine the molecular geometry.

Ammonia is converted to other nitrogen compounds, the most important of which are urea (NH2CONH2), nitric acid (HNO3), ammonium nitrate (NH4NO3), and ammonium sulfate [(NH4)2SO4]. The steric number of NH4+ is 4. CopyCopied, QGZKDVFQNNGYKY-UHFFFAOYSA-O

The steric number of a molecole is defined as number of atoms bonded to the central atom (4) + lone electron pairs on the central atom (0). Steric Number Calculation Examples . Methane (CH 4) - Methane consists of carbon bonded to 4 hydrogen atoms and 0 lone pairs.Steric number = 4.
Steric number is the number of atoms bonded to a central atom of a molecule plus the number of lone pairs attached to the central atom. For a particular number of electron pairs (row), the molecular structures for one or more lone pairs are determined based on modifications of the corresponding electron-pair geometry.
