Locate fluorine (F) on the partial periodic table provided in Figure 2.2. Predict its relative electronegativity compared to hydrogen, sodium, and oxygen. State the number and type of bond(s) you expect it would form if it reacted with sodium (Na).

The fluorine ($F$) is located in the highlighted box on the partial periodic table. The fluorine, oxygen ($O$), hydrogen ($H$), and sodium ($Na$) are placed in the following order on the basis of their relative electronegativity: $F>O>H>Na$ . There will be one bond when fluorine reacts with sodium and the bond will be ionic.
