- 1When is an ionic compound formed?When 2 or more elements are chemically bonded together
- 2When is an ionic compound formed?When a metal and a non-metal are bonded together.
- 3What is an ion?An an atom that has lost or gained electrons to get a full outer shell of electrons.
- 4What do ions always have?A charge
- 5How does an ionic bond form?when metal atoms give electron(s) from their outershell to non-metal atoms to form an ion.
- 6Do metals change their name as they change from an atom to an ion?NO!!!!
- 7Do non-metals change their name as they become ions?YES!!!!
- 8When we hold magnesium in a roaring flame, what do we see?A bright, white light.
- 9When we sprinkle a small piece of Mg over a roaring flame, what do we see?White, bright sparks.
- 10What is the symbol equation for the reaction: Magnesium+Oxygen=Magnesium Oxide2Mg+O2= 2MgO
- 11What is sodium Chloride (salt) made from?Sodium ions (Na+)
Chlorine (Cl-) - 12What do these ions do?Attract each other
- 13What do we say an ionic bond is?The electrostatic attraction between oppositely charged ions.
- 14Why do ionic compounds have HIGH MELTING POINTS?The attraction between + and - is strong.
- 15What are they at room temperature?Solids.
- 16Each sodium atom is attrected to how many chloride atoms?6 chloride atoms and vice versa.
- 17What does this give?A giant structure.
- 18Why don't ionic solids conduct electricity?Because the electrons can't move.
- 19Why do ions conduct electricity when liquid?Because they're free to move.
