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.

Nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.The greater the electronegativity difference, the more ionic the bond is. Bonds that are partly ionic are called polar covalent bonds.Nonpolar covalent bonds.1  A bond between 2 nonmetal atoms that have the same electronegativity and therefore have equal sharing of the bonding electron pair.onds that are partly ionic are called polar covalent bonds.
