covalent bonding

1. Only one pair of electrons is shared between atoms.
6. Molecules composed of only 2 atoms.
8. 2 center, 2electron covalent bond in which 2 electrons derive from the same atom.
9. A chemical bond between atoms involving 6 bonding electrons instead of 2 in a covalent single bond.
10. Pair of valence electrons of opposite spin that arent shared between the atoms in a molecule.
12. Group of atoms bonded together.
13. Formula giving the # of atoms in one molecule of a specific compound.

2. Energy needed to break a covalent chemical bond.
3. Composed of 2 or more atoms covalently bonded with an overall charge.
4. involves the sharing of electron pairs between atoms.
5. A way of describing delocalized electrons within certain molecules where the bonding cant be expressed by one lewis structure.
7. A formula that shows the arrangement of atoms in the molecule of a compound using lines.
11. 2 pairs of electrons are shared between the atoms rather than just one pair.
