For the water molecule (H2O) two hydrogen atoms are needed.
9
Two molecules of ammonia contain 6 hydrogen atoms.
H2O2 2 atoms of hydrogen 2 atoms of oxygen
Twelve. Glucose is C6H12O6, so two molecules of glucose would give you: 12 carbon atoms 24 hydrogen atoms 12 oxygen atoms The 12 molecules of oxygen would give 24 oxygen atoms, for 48 total atoms of oxygen. So...each carbon atom would take two oxygen atoms to give 12 molecules of carbon dioxide, and each remaining oxygen atom would take two hydrogen atoms to give 12 molecules of water.
If you mean two atoms are sharing electrons, then a covalent bond is formed.
protons and neutrons
Just two
For the water molecule (H2O) two hydrogen atoms are needed.
the two atoms belong to two different elements
In a triple bond, a total of six electrons are shared between two atoms. Each atom contributes one electron for a sigma bond, and two atoms contribute two electrons each for two pi bonds.
Hydrogen peroxide (H2O2) contains two atoms of hydrogen and two atoms of oxygen for a total of four atoms.
Yes,there are two atoms.There are two elements.
A water molecule is composed of two hydrogen atoms and one oxygen atom. The formula is H2O.
There are two bromine atoms in Br2
The equation is balanced because the number of each type of atom is the same on both sides of the equation. There are two Cl atoms on the left side and two Cl atoms on the right side, two Na atoms on the left side and two Na atoms on the right side, and two I atoms on the left side and two I atoms on the right side.
Two atoms.
