1 Live in warm, moist environments, including swimming pools and showers.  Can invade your skin through cuts so tiny you can't even see them or through a small separation between your nail and nail bed.
Methane is a hydrocarbon (CH4. Therefore it is COVALENTLY bonded because of the bonds between carbon (non-metal) and hydrogen (non-metal). Ionic compounds only apply to those made of metals and non-metals.ethane is a hydrocarbon (CH4.

An ionic bond is a chemical bond based on electrostatic attraction (the attraction of charges), and we generally associate it with the bonding of metals to non-metals. Salt, that is, table salt, is sodium chloride (NaCl), and it is an ionically bonded compound of one atom of sodium to one atom of chlorine.
