Molecular (covalent) bonding Flashcards
what is a covalent bond
a bond that involves sharing electrons
what elements are involved in molecular bonding
two non-metals
what is a diatomic molecule
two non-metal atoms of the same element, the element wants to bond to itself
what elements are diatomic
hydrogen, oxygen, fluorine, bromine, iodine, nitrogen, chlorine
what are polyatomic molecular elements
non-metal elements composed of many atoms
what is a binary molecular compound
a molecular compound which contains two different non-metal elements covalent bonded
what are the rules for naming molecular compounds
switch the ending do the second element to -ide, use the prefix for the number of each element in the molecular formula
what are the prefixes used for naming molecular compounds
1 - mono
2 - di
3 - tri
4 - tetra
5 - penta
6 - hexa
7 - hepta
8 - octa
9 - nona
10 - deca
which was a higher melting point molecular or ionic compounds
ionic because the very large amount of energy required to break the strong forces of attraction
