Determine the type of chemical bond A) PH3 B) I2 C) BaO D) Ca B2.

Metal and non-metal – ionic bond
Metal – metal bond
Two identical non-metals – covalent non-polar bond
two different non-metals – covalent polar bond
All organic substances have a covalent polar bond
A) PH3 – covalent polar bond (since two different non-metals)
B) I2 – covalent non-polar bond (since two identical non-metals)
B) BaO – ionic bond (since metal and non-metal)
D) CaB2 – ionic bond (since metal and non-metal)
