Demonstrate the way that Carbon and Oxygen can form compounds that have different properties from the elements with examples.
What is CO and CO2 are both made form carbon and oxygen. One is a poisonous gas and one is part of our atmosphere and is needed for photosynthesis?
500
Bonds between metal atoms exist because electrons are this.
What are shared in equally in all directions?
500
Draw a Lewis Dot Structure of O2 and explain how the bond is formed.
What is O=O, covalent bond, shares two electrons each so both atoms are full, 6 valence electrons + 2 shared=stable.
