'H2' means 2 hydrogen atoms, and 'O' means only one Oxygen atom. Whatever number after the chemical symbol for the element, that's how many atoms of it there are.
In a water molecule (H2O), there are two hydrogen atoms.
H20 = 3 or 2 atoms of hydrogen and 1 atom of oxygen.
2 and they are hydrogen and oxygen H20 means their are 2 hydrogen atoms, and 1 oxygen atom
In the chemistry formula, H2O, the "H" stands for hydrogen. The "O" stands for oxygen.
2 atoms of hydrogen and 1 atom of oxygen
H20 is the molecular composition of water. Two hydrogen atoms and one oxygen atom. The hydrogen atoms are pulled to the oxygen atom through forces called hydrogen bonding.
2 hydrogen atoms and 1 oxygen atom.
Two Hydrogen atoms plus one oxygen atom makes h20
No, H20: 2 hydrogen atoms and an oxygen atom
Seeing that H2O is in fact two hydrogen atoms and one oxygen atom, yes. They are connected.
h20 is not an element. because it has hydrogen and oxygen in it.therfore it is a compound.
This is one atom of oxygen in a molecule of water. There are two atoms of hydrogen in that same molecule.
