C2- Bonding, Structure And Properties Of Matter Flashcards
(12 cards)
What are ions?
Charged particles which can be single atoms or groups of atoms
Do metals lose or gain electrons to form positive ions?
Lose
What is ionic bonding?
When a metal and a non-metal react together
What structures and attraction do ionic compounds have?
Giant ionic lattice structure
Electrostatic forces of attraction
What is an example of a giant ionic lattice?
Sodium chloride
Do ionic compounds have a high or low melting point?
High melting point
What are covalent bonds?
When non-metals atoms bond together and share pairs of electrons
What force do covalent bonds have?
Electrostatic
How are covalent bonds drawn in a dot and cross diagram?
Electrons are drawn in the overlap
What type of bonds to simple molecular structures have?
Very strong covalent bonds
Do simple molecular substances have a high or low melting/boiling point?
Low
Why don’t molecular compounds conduct electricity?
They aren’t charged so there is no free electrons
