## Step 1The type of bond that forms between two atoms is determined by the difference in their electronegativities. Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons. The greater the difference in electronegativity, the more ionic the bond is.## Step 2### **Ionic Bond**: This bond forms when one atom donates an electron to another atom. This usually happens between a metal and a non-metal.## Step 3### **Polar Covalent Bond**: This bond forms when two atoms share a pair of electrons unequally. This usually happens between two non-metals.## Step 4### **Nonpolar Covalent Bond**: This bond forms when two atoms share a pair of electrons equally. This usually happens between two identical atoms.## Step 5a) Se and S: Both Se and S are non-metals and they are very close in electronegativity. Therefore, they will form a nonpolar covalent bond.## Step 6b) S and O: S and O are also non-metals but O is more electronegative than S. Therefore, they will form a polar covalent bond.## Step 7c) Na and F: Na is a metal and F is a non-metal. Therefore, they will form an ionic bond.## Step 8d) I and H: I is a non-metal and H is a non-metal. Therefore, they will form a polar covalent bond.
