Ionic bonding

• ionic bonding happens between what?

  a metal and a non metal
• what are ions?

  when atoms lose or gain electrons - a charged particle
• what is ionic bonding?

  strong electrostatic forces of attraction between oppositely charged ions
• what is the charge on a zinc ion?

  2+
• what is the charge of a silver ion?

  1+
• what is the charge of a hydrogen ion?

  1+
• what is the formula and charge of a ammonium ion?

  NH4+
• what is the formula of a ammonia atom?

  NH3
• what is the formula and charge of a nitrate ion?

  NO3-
• what is the formula and charge of a hydroxide ion?

  OH-
• what is the formula and charge of a carbonate ion?

  CO3(2-)
• what is the formula and charge of a sulfate ion?

  SO4(2-)
• what is a lattice?

  regular array of particles
• how is an ionic lattice held together?

  strong electrostatic forces of attraction between oppositely charged ions
• how is the structure of sodium chloride described?

  giant ionic lattice
• why do ionic compounds have high melting and boiling points?

  there are strong electrostatic forces of attraction holding the lattice together

  lots of heat energy is needed to break the strong electrostatic forces between oppositely charged ions
• do ionic compounds tend to be crystalline?

  yes
• why are ionic compounds brittle?

  any small distortion will bring ions of the same charge alongside each other

  like charges repel so it splits
• do ionic substances tend to be soluble in water?

  yes
• do ionic substances tend to be soluble in organic solvents?

  no
• why do ionic compounds not conduct electricity as solids?

  the ions are not free to move
• why do ionic compounds conduct electricity when molten or dissolved in water?

  the ions are free to move
• what is the charge on a copper ion?

  2+
• what is the charge on a lead ion?

  2+
