This question doesn't make sence as an atom is a unit. Hydrogen can be measured in number of atoms.
hydrogen
A hydrogen atom. One proton, and one surrounding electron.
I'm pretty sure its a hydrogen atom
A pure substance made of only one type of atom is an element.An element, or elementary substance.An element.
A hydrogen bond, which is a type of weak bond that forms between a hydrogen atom and an electronegative atom such as oxygen.
No, H20: 2 hydrogen atoms and an oxygen atom
The type of intermolecular force present in KOH is hydrogen bonding. Hydrogen bonding occurs between the hydrogen atom of one molecule and the oxygen atom of another molecule when hydrogen is bonded to a highly electronegative atom such as oxygen.
A hydrogen bond is the type of bond that attracts an oxygen and hydrogen molecule. In a hydrogen bond, the hydrogen atom from one molecule is attracted to the electronegative oxygen atom of another molecule.
monounsaturated
H symbolises one hydrogen atom. H2 symbolises two hydrogen atoms bonded together or sharing electrons. They are the same because they contain only one type of atom: the hydrogen atom, one proton and one electron
