H2O - or in other words, water
When two atoms of hydrogen combine with one atom of oxygen- water is made H2O
There are two nitrogen atoms and one oxygen atom.
An oxygen atom consists of one oxygen nucleus and one electron, while an oxygen molecule consists of two oxygen atoms bonded together. The oxygen molecule is the stable form of oxygen that we breathe, while oxygen atoms are highly reactive and rarely exist on their own in nature.
A CO2 molecule consists of 3 atoms: 1 carbon atom and 2 oxygen atoms.
Four.
2 hydrogen atoms and 1 oxygen atom.
Three, two hydrogen and one oxygen. The suffix after the H tells you that there two, no suffix after O tells you there is only one.
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.
Atoms. Some atoms can not exist without another atom/s to stabilise it and form a molecule For example, the O2 (oxygen) molecule consists of two O (oxygen) atoms. The H2O (water) molecule consists of two H (hydrogen) atoms and one O (oxygen) atom.
An oxygen atom is an atom with eight protons and eight electrons. An oxygen molecule is a particle that consists of two oxygen atoms that are bonded together.
none, since hydrogen is a pure chemical element consisting of only hydrogen atoms.
3 atoms. 1 carbon atom and 2 oxygen atoms.
