    A) Trigonal Planar, with each of the pairs remaining in the same plane seperated at 120 degree angles from each other.

    B) Tetrahedral, with each of the pairs sitting at each corner of the tetrahedron, 109.5 degrees between each pair.

    properly, the electrons are not actually sitting there next to a minimum of one yet another. they're in consistent action. the assumption of paired electrons is for bonding. There can, besides the incontrovertible fact that, be a single electron. Take nitrogen, as an occasion. It has 5 valence electrons, so 2 factors could have pairs, and one section could have an electron via itself. enable's say we might have liked to bond this with Fluorine. F has 7 valence electrons, so it additionally has a lone electron on one section, so this may be the area that the lone nitrogen electron could bond, coming up a bond with 2 electrons. back, do no longer forget that electrons are continuously moving at very nearly the value of light. they're under no circumstances in simple terms sitting next to a minimum of one yet another, this is basically a thank you to truthfully visualize how bonding works. desire this helped, i'm nonetheless analyzing Chemistry.
