Science - Chemistry: Ionic Bonding

Question 1

ionic bonding

Answer 1

a chemical bond between a metal and non-metal

Question 2

metals and non-metals

Answer 2

metals: cations
non-metals: anions

Question 3

naming ionic compounds

Answer 3

cation + anion
add -ide to the end of the anion
e.g. MgCl = Magnesium Chloride

Question 4

what happens between atoms?

Answer 4

electrons are given from the cations to make full valence shells on both atoms

Question 5

forming cations

Answer 5

• elements with <4 electrons lose electrons
• form a positive ion
• charge = +

Question 6

forming anions

Answer 6

• elements with >4 electrons gain electrons
• form a negative ion
• charge = -
