Steric Number Definition in Chemistry - ThoughtCo
网页2019年10月5日 · The 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. The steric number of a molecule is used in VSEPR (valence shell electron pair repulsion) theory to determine the molecular geometry of a molecule.
Steric Number: Definition, Formula, and Chart - Chemistry Learner
网页The steric number is the number of atoms bonded to the central atom of a molecule plus the number of lone pairs of electrons on the central atom. In other words, the steric number tells us how many regions of electron density are present in a molecule.
Steric Effects - Michigan State University
网页Steric Effects. When two neutral atoms (A & B) are close enough to detect each other, they experience an attraction due to dispersion forces. The green dashed curve in the illustration on the right represents this attraction, which increases with the inverse sixth power of the distance between the atoms (r).
