Labels:text | screenshot | font OCR: This type of bonding is called covalent bonding and occurs where a pair of electrons is shared between 2 atoms. Each atom contributes 1 electron to the bond. In some instances double covalent bonds occur. Oxygen for example tends to form into molecues of O, (two atoms of oxygen bonded together). An atom of oxygen has 6 electrons in it's outer shell and shares a pair of electrons with another atom of oxygen. Each oxygen atom therefore donates 2 electrons to the bond hence the term double covalent bonding. + E 0: 2,6 2,6 The bonding between atoms is shown by lines; 1 line for a single bond and 2 lines for a double bond. Some common molecues are written as follows. Can you work out their bond structures? Water Oxygen H-C-H H-0-H 0=0 Methane H
