What atoms make up a molecule of water H20?
Select all that apply.
Oganesson
Oxygen
Helium
Hydrogen
Oxygen and Hydrogen atoms make up a molecule of water, H2O.
The atoms that make up a molecule of water (H2O) are Oxygen and Hydrogen.
The correct answers are Oxygen and Hydrogen.
To determine the atoms that make up a molecule of water (H2O), we need to understand its molecular formula, which provides information about the types and number of atoms present.
In this case, the molecular formula for water is H2O, indicating that there are two hydrogen atoms (H) and one oxygen atom (O) within each water molecule. Therefore, Oxygen and Hydrogen are the atoms that make up a molecule of water.
Oganesson and Helium are not involved in the composition of water.
