COMPOUNDS part one: ionic compounds

[object Object],COMPOUNDS are chemically combined two or more elements in which the elements + = Na Cl NaCl

[object Object],IONIC COMPOUNDS

[object Object],IONIC COMPOUNDS one or more positively charged ions and one or more negatively charged ions

[object Object],IONIC COMPOUNDS elements combine by transferring electrons from one atom to another

[object Object],IONIC COMPOUNDS + = Na Cl NaCl

[object Object],is transferred from a sodium atom to a chlorine atom IONIC COMPOUNDS

[object Object],IONIC COMPOUNDS becomes a positively charged ion Na + Na +

[object Object],IONIC COMPOUNDS to indicate that the sodium has a charge of 1+ Na +

[object Object],Cl - IONIC COMPOUNDS to become a negatively charged ion Cl -

[object Object],indicate that the chlorine ion has a charge of 1- Cl - IONIC COMPOUNDS

[object Object],their outermost shell IONIC COMPOUNDS

[object Object],or contains the maximum number of electrons IONIC COMPOUNDS

[object Object],Non-metal atoms tend to gain electrons IONIC COMPOUNDS

[object Object],electrons it becomes positive called a cation (“cat-eye-on”)

[object Object],electrons it becomes negative called an anion (“an-eye-on”)

Ca + ions are posi + ive A n ions are n egative

[object Object],positive nucleus, the more easily it is removed and the more reactive the atom is

[object Object],CATIONS Lithium Sodium Potassium Rubidium Cesium

[object Object],Fluorine Bromine Iodine Astatine ANIONS Chlorine

[object Object],IONIC COMPOUNDS brittle solids that can be crushed

IONIC COMPOUNDS In an ionic crystal, every ion is attracted to every other ion in the crystal. As a result, ionic crystals have very high melting points ex.) NaCl melts at 800 o C

[object Object],IONIC COMPOUNDS conduct electricity

[object Object],to acquire a full valence shell

[object Object],For many atoms, this arrangement resembles the
