Covalent bonding
- 1. Covalent Bonding • Bonding between elements that are ____-_________ • Atoms get full ______ shells by ________ electrons • Outer shells “____________” [anagram: polevra] This is a covalent bond between two hydrogen atoms, H2 Try to draw the bond between two fluorine atoms
- 2. Covalent Bonding • Bonding between elements that are non-metals • Atoms get full outer shells by sharing electrons • Outer shells “overlap” [anagram: polevra] This is a covalent bond between two hydrogen atoms, H2 Try to draw the bond between two fluorine atoms
- 3. A covalent bond is a pair of shared electrons • If 1 pairs of electrons is shared we call this a single bond • If 2 pairs of electrons are shared we call this a double bond
- 4. Draw a dot-cross diagram to show the covalent bonding in . . . Hint: just show the outer shell of electrons in each atom • Bromine, Br2 • Oxygen, O2
- 5. Properties of covalent molecules Unlike in ionic bonding, there is very little attraction between one covalent molecule and the next. We call them SIMPLE molecules They have low melting points, and are usually gases or liquids. There are no charges that can move, so they do not conduct electricity
