Small covalent molecules Flashcards
1
Q
How does a molecule form
A
when 2 non-metal atoms share pairs of electrons to complete their outer shells, making them stable, this forms a covalent bond
2
Q
Dot & cross diagrams show
A
the sharing of pairs of electrons in the outer shell
3
Q
Properties of small molecules
A
don’t conduct electricity, have low melting and boiling points
4
Q
Why do small molecules not conduct electricity
A
all electrons are used up in bonding, therefore there are no free electrons to carry a charge
5
Q
Why do small molecules have low melting/boiling points
A
it requires little energy to break the weak intermolecular forces to change its state
6
Q
electricity
A
