how many atoms is one molecule?
528442
1 Answer. Molecule: group of two or more atoms held together by chemical bonds. So, minimum 2 atoms are required to form a molecule. E.g. An oxygen molecule ( O2 ) contains 2 oxygen atoms.

An atom is an element. The two words are synonymous, so if you're looking for the number of atoms in an element, the answer is always one, and only one.

1 mole of hydrogen gas contains 6. 02×1023 atoms. 1 molecule of hydrogen(H2) contains two atoms of hydrogen.

Recall that two hydrogen atoms bind to make a hydrogen molecule. The same can be said of one mole of any other substance where two atoms combine to make a simple molecule.

Just in case you didn't know, one elephant has one trunk and four legs, and one molecule of methane (CH4) contains one carbon atom and four hydrogen atoms. So, one mole is equal to 6.02 x 10²³ atoms (or molecules) of a substance, in the same way that 12 of anything makes up a dozen.

The number of atoms of ANY substance in a volume is: # of atoms = N * (density) * volume / (Molecular Weight). N is a constant called Avogadro's number and its equal to 6.022*1023 atoms/mole. It can also be molecules per mole.

An atom is the sub-component of a molecule, or the smallest unit of matter. It is the smallest part an element can divide into. A molecule is made up of atoms that are bound by ionic, covalent or metallic bond.

Each mole is 6.02214179 * 10^23 molecules. So we have 1.670829 *10^21 molecules. Each molecule of water has three atoms (two hydrogen, one oxygen). So we have 5.0124896 *10^21 atoms in one drop of water.

Therefore, 4 moles of , or any other molecule is molecules. Now, each molecule of has 3 atoms (1 carbon & 2 oxygen); thus, there would be individual atoms, assuming every molecule is purely .

Hydrogen (H2), oxygen (O2), and chlorine (Cl2) molecules, for example, each contains two atoms. Another form of oxygen, ozone (O3), has three atoms, and sulfur (S8) has eight atoms. All elemental molecules are made of atoms of a single element. Fig.

In one mole of hydrogen atoms, there exists approximately 6.02⋅1023 hydrogen atoms.

There are three atoms in a water molecule. 2 atoms of hydrogen and 1 oxygen atom. There 2 hydrogen and one oxygen atom so total 3 atom.

The atom is the smallest and most fundamental unit of matter. It consists of a nucleus surrounded by electrons. Atoms form molecules. A molecule is a chemical structure consisting of at least two atoms held together by one or more chemical bonds.

One molecule of glucose has 6 atoms, as you can see in carbon's index. ( C6 ). In 20 molecules there will be 6⋅20 carbon atoms. So, written down like this there are 20⋅6 carbon molecules, 12⋅20 hydrogen atoms and 6⋅20 oxygen molecules.

A molecule is a group of two or more atoms joined together by covalent bonds. Molecules of the same element or compound always contain the same number of atoms of each element. The atoms in a molecule are always joined together by a covalent bond. Substances that are made up of ions do not form molecules.

The mole, abbreviated mol, is an SI unit which measures the number of particles in a specific substance. One mole is equal to 6.02214179×1023 atoms, or other elementary units such as molecules.
