What particle determines the name/identity of the element?

What phase of matter has particles that are held together but can flow past each other and takes the shape of a container, filling it from the bottom up?

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.

What does an electron configuration for an atom relate to the atoms placement on the periodic table
