Question

1. The element phosphorus would be expected to form ___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:

2. The electron-pair geometry around the P atom in PCl4+ is ____.
There are ___lone pair(s) around the central atom, so the geometry of PCl4+ is ___.

3. The electron-pair geometry around the Al atom in AlBr3 is ___.
There are ___lone pair(s) around the central atom, so the geometry of AlBr3 is ___.

Answer 1

 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__.
