Covalent bonding Flashcards
1
Q
Covalent bond
A
a bond formed by sharing a pair of electrons between two atoms
2
Q
molecule
A
a particle having two or more atoms joined by covalent bonds
3
Q
what is a lone pair
A
a pair of electrons in the outer shell of an atom in a molecule which does not form a covalent bond
4
Q
rules with dot and cross diagrams
A
we usually only show outer electrons
we use a dot for electrons from on the other atoms and a cross for the electron of the other
5
Q
what are intermolecular forces
A
the weak forces between molecules
6
Q
properties of ionic compounds
A
not volatile
soluble in water
do not conduct
strong forces of attraction
7
Q
properties of simple covalent compounds
A
many are volatile
most are soluble
do not conduct
weak forces of attraction
