C3 - Structure and Bonding Flashcards
What are the complex ions?
Carbonate
Sulphate
Nitrate
Hydroxide
Ammonium
If the ion ends in -ide what does that mean?
It is on its one (Me myself and -ide) funny haha
If an ion ends in -ate what does that mean?
It has a mate haha funny
What is an isotope?
It is atoms with the same number of protons but different numbers of neutrons and therefore different atomic masses.
What process do you use to go from a solid to liquid?
melting
What process do you use to go from a liquid to gas?
evaporation or boiling
What process do you use to go from a gas to liquid?
condensing
What process do you use to go from a liquid to solid?
freezing
What process do you use to go from a solid to gas?
sublimination e.g. dry ice
What are diatomic molecules?
Elements that can’t be alone e.g. oxygen (oxide), chlorine(chloride),
Compounds made up of ions are called what?
Ionic compounds
How are ionic compounds held together?
By strong forces of attraction between their oppositely charged ions.
Why do ionic compounds have high melting points?
Because it takes a lot of energy to break the many strong ionic bonds
What state are ionic compounds at room temperature?
Solid
Why do ionic compounds conduct electricity when molten or dissolved in water?
Because their ions can then become mobile and can carry charge through the liquid
What are some properties of ionic compounds?
conducts electricity
high melting point
solid at room temperature
soluble in water
How are ionic bonds formed?
between a non-metal and a metal- opposites attract
