Question

In three to five sentences, using the periodic table of elements predict the bonding activity between phosphorous and chlorine. Why do you think they would bond that way?

This is what I have so far, can you help me finish the rest…
Using the periodic table of elements we can figure out how many valance electrons both phosphorus and Chlorine have. Because Phosphorus (P) is in the VA group it has 5 three valence electrons

Answer 1

while Chlorine (Cl) is in the VIIA group with 7 valence electrons. This indicates that both elements would like to gain or lose electrons to achieve a stable electron configuration. Phosphorus can gain 3 electrons to achieve a full valence shell, while Chlorine can gain 1 electron to complete its outermost shell. Due to their electron configurations and electronegativity difference, phosphorus and chlorine are likely to form an ionic bond, where phosphorus loses electrons to become positively charged and chlorine gains electrons to become negatively charged, thus attracting each other in a bond.
