Ionic compounds form in strict ratios of anions to cations to gain overall neutrality. For example, Ca 2+ and Cl - will form an ionic lattice in the ratio 1 : 2 (1 × 2 + 2 × (-1) = 0).
Lattice: ordered arrangement / regular arrangement Lattice structure of ionic compounds consists of a regular arrangement of alternating positive and negative ions. (MUST LEARN!) The ions attract each other strongly and are held together in the lattice structure by strong ionic bonds. Cubic lattice structure of Sodium chloride
15. Ionic Bonds Worksheet. Ionic bonds form between ______________ and _________________. In naming simple ionic compounds, the ____________ is always first, the ____________ second (e.g., sodium chloride). Ionic compounds dissolve easily in ________________ and other polar solvents.
Rubidium reacts with bromine to form an ionic compound. Which row shows the electron change taking place for rubidium and the correct formula of the rubidium ion?
Chapter 6 Practice Worksheet: Ionic Bonds and Some Main-Group Chemistry. Write electron configurations of the following ions: K+ (long hand notation): 1s2 2s2 2p6 3s2 3p6. F- (long hand): 1s2 2s2 2p6. Ni2+ (short hand): [Ar] 4s0 3d8. Zn2+ (short hand): [Ar] 4s0 3d10. Br- (short hand): [Ar] 4s2 3d10 4p6.
charged ions attract each other through electrostatic forces to form a giant ionic lattice . Example: Sodium chloride is an ionic compound formed from Na + and Cl - ions. Sodium loses an electron and chlorine gains an electron to produce ions with a full outer electron shell. These then form a giant ionic lattice.
