A hydrogen atom may contain zero one or two?

A hydrogen atom may contain zero, one, or two electrons. The number of electrons in a hydrogen atom determines its charge and chemical properties. A hydrogen atom with no electrons is a proton, while a hydrogen atom with one electron is a neutral species, and with two electrons it becomes a negatively charged ion.


How many atoms of oxygen and hydrogen for carbo monoxide?

Carbon monoxide (CO) consists of one carbon atom and one oxygen atom. It does not contain hydrogen atoms. Therefore, in carbon monoxide, there is one atom of oxygen and zero atoms of hydrogen.

What does a molecule of water contain one atom of?

H2O means two atoms of hydrogen and one atom of oxygen.


How many electrons are in a positively charged hydrogen atom?

None. A hydrogen atom has one proton and one electron (no neutron). Removing the electron leads to just a proton, no electrons.


Which atom do not contain neutron?

A hydrogen atom that does not contain a neutron hydrogen ions can can be thought of as?

Hydrogen H+ ion is (i.s.o. 'can be thought of as ...) one proton.


How H and H2 both can be elements?

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


Does one molecule of water contain one atom of hydrogen and one atom of oxygen?

No; water is H20 and therefore consists of one carbon and two hydrogen atoms.
