Assume that one particular atom of rhodium (Rh) has a mazs of 102. Why does this numder not exactly match the atomic mass of 102.91listed on the periodic table for this element

Which substances have the lowest melting points: ionic covalent, or metallic

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.

Consider the four elements above. which one of these elements will combine with oxygen in a 1: 1 ratio?
