Based on its location in the periodic table, what can most likely be predicted about phosphorus?
it has three valence electrons available for bonding.
it has three nonbonding electrons.
it has five valence electrons available for bonding.
it has five nonbonding electrons.

The correct option is this: IT HAS FIVE VALENCE ELECTRONS AVAILABLE FOR BONDING.

Phosphorus belongs to group 15 in the periodic table of element. It has atomic number of 15 and its electronic configuration is 2, 8,5. This electronic configuration implies that, the element has five electrons in its outermost shell. Because it needs three more electron to attain the octet form, phosphorus is reactive in nature and will react with suitable elements to form compounds. Phosphorus exist in three forms in nature, we have white, red and black phosphorus. Based on its location on the periodic table it can easily know that phosphorus has five electrons in its outermost shell because all the elements in that group has five valence electrons.
