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 when an electron leaves one atom and exothermically enters into orbit around another. These to oppositely charged ions now attract eachother. Ionic bonds are generally formed between metals and nonmetals. Ionic bonds result from the mutual attraction between oppositely charged ions.They tend to be stronger than covalent bonds due to the coulombic attraction between ions of opposite charges. To maximize the attraction between those ions, ionic compounds form crystal lattices of alternating cations and anions. The atoms are thus held together by the attractive force between a positively and a negatively charged ion. An ionic bond is typically formed between a metal and a non-metal. A bond between two elements caused by a difference in charge created by the donation of an electron by one of the atoms to another.
