Forming NaCl from Na and Cl2 2
• A metal atom can transfer an electron to a nonmetal. • The resulting cation and anion are attracted to each other by Electrostatic Forces Electrostatic Forces
Force of attraction = (charge on +)(charge on -) (distance between ions)2 electrostatic forces. The oppositely charged ions in ionic compounds are attracted to one another by ELECTROSTATIC FORCES . These forces are governed by COULOMB’S COULOMB’S LAW. As ion charge increases, the attractive force _______________. As the distance between ions increases, the attractive force ________________. This idea is important and will come up many times in future discussions! Importance of Coulomb’s Law NaCl, Na+ and Cl -, NaCl, and m.p. 804 oC MgO, Mg2+ and O2MgO, and m.p. 2800 oC Page 1 ...
