So lol, Lets say my grade is a 81 in chemistry, and I make a 100 on 3 assignments which is 30% of my grade, what will my grade change too?

Which statement describes james chadwick’s discovery.

According to the valence shell electron pair repulsion (vsepr) theory, a molecule that has four electron groups around the central atom will exhibit what electron geometry? view available hint(s) according to the valence shell electron pair repulsion (vsepr) theory, a molecule that has four electron groups around the central atom will exhibit what electron geometry? trigonal bipyramidal tetrahedral square planar determination of electron geometry requires information on whether the electron groups are lone pairs or bonding groups.

May someone me with these science questions
