covalent bonding and structure Flashcards
1
Q
what is covalent bonding
A
the electrostatic attraction between a shared pair of e- and the positive nuclus of an atom or element
2
Q
which elements take part in covalent bonding
A
two non metals
3
Q
how do you draw a covalent bond
A
dot and cross diagram with overlapping shells
4
Q
what is a dative covalent bind
A
where both e- is a shared pair are provided by one element
5
Q
what are the properties of covalent counds
A
most are simple covalent molecules that only have weak imp between molecules and therefore have low melting and boiling points
but giant covalent lattices have incredible strong covalent bonds between molecules and therefore have very high strength and meting/ boiling points
