Answer AND Explanation:
When sodium atoms bond with one oxygen atom they form a covalent bond. However, there has to be two sodium atoms each with an extra electron that are donated to oxygen. Each of these sodium atoms gives oxygen one electron, allowing the oxygen atom to have a full shell with eight electrons. The sodium atom loses one orbital level since the electrons are donated.
4Na + O2 → 2Na2O
Plants use carbon dioxide and sunlight to make their own food and grow. The carbon becomes part of the plant. Plants that die and are buried may turn into fossil fuels made of carbon like coal and oil over millions of years. When humans burn fossil fuels, most of the carbon quickly enters the atmosphere as carbon dioxide.
