Answer 2

negative ions/anion ions

Question 3

metals usually form__ in ionic compounds

Answer 3

positive ions / cations

Question 4

charge can be found by..

Answer 4

finding difference between number of electrons and protons

Question 5

ionic bonding

Answer 5

•metals+non-metal
•electron transferred
•ions arranged in an ionic lattice , held together by STRONG electrostatic forces of attraction
-conduct electricity when molten or aqueous

Question 6

why ionic compound can conduct electricity when in aqueous and molten state ?

Answer 6

ions are free to move in aqueous and molten state

Question 7

ionic compound structure

Answer 7

• giant ionic crystal lattice structure
• held by very strong intermolecular forces of attraction
=high melting and boiling points
•usually soluble in water but insoluble in organic substances
