In an ionic bond, the atoms are bound together by the electrostatic forces in the attraction between ions of opposite charge. The basic unit of ionic compounds is not a molecule, but a formula unit. Predict the molecular geometry (shape) of each molecule and indicate whether it is polar or nonpolar. However, even in covalent compounds, where the valence electrons are shared, the sharing is not equal when oxygen is involved. Since there's few time left, I'll answer them all. In a period the stability increases with increasing electronegativity. Activities and Labs: Lab: DHMO Research. For each of the binary (2 elements) compounds look at the formula and classify each of the 2 elements present as metal or nonmetal. Each Ca atom transfers one electron to each fluorine atom. •Due to the weak van der Waals forces that hold molecules together, covalent compounds have low melting and boiling points; because the weak forces between molecules. , H 2O, PF 5) or ionic (e. 11) For each of the following compounds, place a point on the bond-type triangle.
