Structure The gas methane (CH ₄) is composed of … ,[object Object],[object Object],+ Carbon Hydrogen 6 2 4 C 12.0107 amu H H H H C 6 protons 6 neutrons 6 electrons 1 proton no neutrons 1 electron x = 4.03176 amu 4.03176 au + 12.0107 au = 16.04246 amu 1.00794 amu Structure of an element Atomic Number Chemical Symbol Chemical Name Atomic Weight Electronic Configuration 1 1 H Carbon Hydrogen Atomic Mass of Methane: 16.04246 amu x 4

Bonding ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],How does it work? Carbon has 4 electrons on its valence shell. Hydrogen has 1 electron on its valence shell. Since neither is a metal or close to completing their outer shell, they bond covalently. The atoms will gravitate towards toward the carbon atom because it is stronger. What type of bond is formed between the hydrogen and carbon atom? What type of covalent bond forms? ,[object Object],[object Object],Methane
