When excited electrons cascade to lower energy levels in an atom a)visible light is always emitted b)the potential energy of the atom increases c)the electrons always fall back to the first energy level d)the electrons fall indiscriminately to all levels e)the electrons fall back to a lower unfilled energy level

How many grams of co(g) are there in 74.5 ml of the gas at 0.933 atm and 30o c?

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.
