No. Elemental hydrogen only exists as a diatomic molecule.
name the different allotropes of silicon?
In that case, scientists talk about different "allotropes". For example, graphite and diamond are different varieties of carbon - the same atoms, in a different arrangement.
two allotropes of boron ; crystalline boron and brown amorphous boron
Allotropes
probably
No.
Yes ofcourse Hydrogen have two allotropes, Ortho hydrogen and para hydrogen. They differ only in having parallel and anti parallel nuclear spins. It was first observed by Heisenberg in 1927. BY RAJESH KUMAR GDC MPM SINDH PAKISTAN
No. Water is a chemical compound and a pure substance. Hydrocarbons are a large class of compounds which are composed of the elements hydrogen and carbon. Allotropes are forms of the same element with a different arrangement of atoms (example: graphite and diamond are both pure carbon.)
The 2 metal which exist in gases state are metallic hydrogen and the two allotropes of oxygen which are dioxygen and ozone.

phosphorus
Yes, P4 and P8 (also P12) are all allotropes.
No, it does not have any allotropes.
In that case, scientists talk about different "allotropes". For example, graphite and diamond are different varieties of carbon - the same atoms, in a different arrangement.
No water is not an allotrope and it can not have allotropes because it is not an element.
two allotropes of boron ; crystalline boron and brown amorphous boron
Allotropes are versions of the same element or compound with a different molecular structure.
