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.

1 As a result, they all have a tetrahedral arrangment of electron pairs around the central atom. 2  The bond angle in methane, CH 4, is the tetrahedral angle, i.e. 109.5 (109 28'). 3  Ammonia, NH 3, contains a lone pair of electrons, which repels the bonding electrons to give a bond angle of 107.
