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. 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.
A covalent bond is a chemical bond between two nonmetals (two metals cannot covalently bond) in which electrons are shared, while an ionic bond is a chemical bond between a me â¦ tal and a non metal due to the attraction between oppositely charged ions.or example water is H2O. Oxygen needs two more electrons to have a full valence (â¦ outer shell) and each hydrogen needs one electron, so they share electrons to form the stable compound water. An ionic bond is a bond between a metal and a nonmetal, where there is an exchange of electrons.
