g Identify each term as a description of an electron geometry or a molecular geometry. Arrangement of only the atoms in a molecule Electron geometry Tetrahedral for N F 3 Molecular geometry Arrangement of bonding and non-bonding electron domains Electron geometry Trigonal pyramidal for N F 3 Molecular geometry

ca has a crystalline lattice with positive ions (since it is a metal, metals are positively charged) and electrons flow freely in its structure since the ca atoms have a large nuclear radius so the electrons are not tightly held, therefore the electrons can flow freely since they are not being highly attracted by the nucleus. moreover, one of the properties of metals are that they are conductors of electricity, thus proving ca is the element.
