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.

A covalent bond is formed between two non-metals that have similar electronegativities. Neither atom is strong enough to attract electrons from the other. For stabilization, they share their electrons from outer molecular orbit with others.
