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
this is called, pacholskybutthole
This compound is called calcium permanganate.
The compound BiF5 is called bismuth pentafluoride.
It is Methene.
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?
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.
The name "methene" is not commonly used because it would imply the presence of a carbon-carbon double bond, which is not the case. Instead, compounds with a carbon-carbon double bond are typically named using the suffix "-ene" in organic chemistry nomenclature.
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.

When a compound lacks water, it is called anhydrous.
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.
The individual leaflets of a compound pinnate leaf are called leaflets.
This compound is called calcium permanganate.
