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.

The positively charged ion is called cation, and the negatively charged ion is called anion. An ionic bond between a cation A+ and an anion B- is commonly described by writing the cation and anion together, viz., A+B-. An ionic (or electrovalent) bond is formed between two ions of opposite charges. During the formation of an ionic bond, one of the reacting elements should form a positively charged ion (cation), and the other should give a negatively charged ion (anion). This is possible only if, one of the atoms loses one or more electrons and the other gains one or more electrons.
