1. What do the physical and chemical proper- The chemical bonds and intermolecular
ties of a compound depend on? forces
2. True or False False
When forming ions, all atoms of elements Transition metals do not always achieve
achieve the electron configuration of a no- the noble gas electron configuration
ble gas
3. What causes the crystalline structure of ion- Regular arrangement of ions within struc-
ic compounds? ture
4. Define Ionic Bonding The electrostatic attraction between oppo-
sitely charged ions in an ionic lattice
5. How are positive ions formed? The loss of electrons
6. How are negative ions formed? The gain of electrons
7. What ions do metals usually form? Positive ions

Why do ionic compounds have high melting There is a strong electrostatic attraction
points? between the oppositely charged ions in
the ionic lattice
Requires a large amount of energy to
overcome
14. True or False True
Metal atoms can form covalent bonds e.g. BeCl2
15. True or False True
Covalent bonds have the same properties as
coordinate bonds
16. True or False False
Ionic compounds dissolve in non-polar sol-
vents
17. Why is the melting point of MgCl greater Magnesium is a smaller ion (ionic radius)
than the melting point of NaCl? Higher charge
Greater charge density
Stronger electrostatic attraction between
oppositely charged ions
Stronger ionic bond
18. When do ionic compounds conduct electric- When molten or in solution
ity?
19. Why can ionic compounds conduct electrici- The ions are free to move and carry charge
ty when molten or in solution?
20. Why are some ionic compounds soluble in The water molecules hit the ionic lattice
water? and knock off the ions.
