There is no compound called methene since all aliens contain atleast one double bond between carbon atoms. The prefix meth suggests there is only one carbon and this carbon atom cannot double bond to itself.
All alkenes have carbon-carbon double bonds, with only one carbon in 'methene', there's no way for the single carbon atom to bond with anything. The carbon atom can't possibly bond itself, right?

Sulphur forms compound called sulphides, sulphates, sulphites and others
It is Methene.
You can't draw a structural formula for methene because the prefix meth- means one carbon atom is present in the whole compound, and the suffix -ene means there is at least one double bond between only carbon atoms in the compound. If you added the other carbon atom necessary for the double bond it would change the name to ethene.

methene
Methene doesn't exist; it would have the formula CH2. This would be infinitely too reactive. Meth- means that there is one carbon atom present. But all alkenes have a carbon double bond so methene wouldn't be classed as an alkene even if it existed.
NaCI
The natural compound of a metal is called Ore.
If it is a molecular compound, the smallest unit is called a molecule. If it is an ionic compound, the smallest unit is called a formula unit.
A white crystalline compound is also called cytidine.
