Covalent bonding Flashcards
1
Q
What is a molecule?
A
A compound formed by strong covalent bonds
2
Q
What is a covalent bond?
A
The sharing of electrons on the outer shells of two or more non-metal atoms.
3
Q
Draw a dot and cross diagram to show the covalent bond for hydrogen
A
draw (not really hard :)
4
Q
What forces hold simple molecules together?
A
Strong forces of attraction caused by a covalent bond
5
Q
How do you work out the molecular formula for covalent compounds?
A
For example:
CO2
how many electrons needed to complete outer shell for Carbon, 2
This means that there are 2 covalent bond since oxygen joins.
(something like that)
