The element phosphorus would be expected to form _3__covalent bond(s) in order to obey the octet rule. Use the octet rule to predict the formula of the compound that would form between phosphorus and fluorine , if the molecule contains only one phosphorus atom and only single bonds are formed. Formula:
"PF_3"
2. The electron-pair geometry around the P atom in PCl4+ is _tetrahedral___.
There are _no__lone pair(s) around the central atom, so the geometry of PCl4+ is _tetrahedral__.
3. The electron-pair geometry around the Al atom in AlBr3 is trigonal planar___.
There are no___lone pair(s) around the central atom, so the geometry of AlBr3 is _trigonal planar__.
