Ionic bonding (P1C5) Flashcards
What is the easy method to work out a nonmetal’s charge?
A nonmetal’s charge is its group number minus 8.
What is the easiest method to work out a metal’s charge using only the periodic table?
A metal’s charge is its group number.
Which type of atoms create negative ions?
Non-metal ions create negative ions.
Which type of atoms create positive ions?
Metal atoms create positive ions.
What does the mnemonic OIL RIG mean?
Oxidisation Is Loss, Reduction Is Gain.
Ionic bonds are only present in what combination of metals and nonmetals?
Ionic bonds form from a metal and a nonmetal.
What determines how reactive an element is?
An element’s ability to gain or lose electrons determines how reactive it is.
What determines an element’s melting point and boiling point and why?
An element’s melting point and boiling point is proportional to the charge of the ion because more charged ions require more energy to break the electrostatic bonds.
How is the yield of a reversible reaction affected if the concentration of one of the reactants is increased?
If the concentration of one of the reactants is increased, the reaction will produce more of the other reactant due to a change in equilibrium.
Do ionic compounds typically have low melting and boiling points?
No; ionic compounds have high melting and boiling points due to strong electrostatic forces.
Do ionic compounds conduct electricity?
No; ions are not free to move in an ionic compound and therefore cannot conduct electricity.
Do ionic compounds conduct electricity when molten or in a solution?
Yes; the charged ions are free to move and conduct electricity.
