A hydrogen atom is about 1836 times lighter than a single hemoglobin molecule. This is because the Atomic Mass of a hydrogen atom is approximately 1 atomic mass unit (amu), while the molecular mass of a hemoglobin molecule is roughly 1836 amu.
The size of a carbon atom is larger than that of a hydrogen atom due to the larger number of protons, neutrons, and electrons in a carbon atom. Multiple carbon atoms can bond together to form larger carbon molecules, such as hydrocarbons, which can be much larger in size compared to hydrogen molecules which exist as individual atoms.
The bonds that connect hydrogen molecules to oxygen molecules in water are covalent bonds. In a water molecule, each hydrogen atom forms a covalent bond with the oxygen atom by sharing electrons.
Water molecules can form hydrogen bonds with other water molecules as well as with molecules containing oxygen or nitrogen atoms, such as alcohol, amine, and carboxylic acid molecules.
In the formula 2CaCO3, there are 2 molecules of calcium carbonate (CaCO3) in total. Each molecule of calcium carbonate consists of one calcium atom, one carbon atom, and three oxygen atoms.
Fluorine typically forms molecules by bonding with itself (F2). Each fluorine atom shares one electron with another atom to complete its outer electron shell. This results in a diatomic molecule, rather than existing as single atoms or crystal lattices.
Iron. In the blood, the red substance, haemoglobin, is found in red blood corpuscles. This haemoglobin is a protein whose use is to transport oxygen round the body (obtained from the lungs) to the cells that need it, and waste carbon dioxide from the cells that need to get rid of it, which it transports back to the lungs for us to breathe out. Haemoglobin molecules contain an atom of the metal iron at the centre. So if you are anaemic, this is because you do not have enough haemoglobin - usually as a result of iron deficiency.
Moelcules are made from atoms but a large atom is very many times the size of small molecules.
The red colour is caused by a chemical known as a porphyrin which actually contains the iron atom in haemoglobin. The name porphyrin comes from the Greek for purple. There are lots of different kinds of haemoglobin depending on which species you belong to, but all have a similar structure of protein molecules and iron containing porphyrin molecules. Oh I forgot, the porphyrin molecule in haemoglobin is called ha em or heme, depends on where you come from. If you are interested some animals like octopus and squid have copper instead of iron in their oxygen carrying molecules.
The protons and neutrons, but not the electrons since they are about thousand times lighter than protons and neutrons.

why atom and molecules are important to cell processes explain
A helium atom is four times lighter than a carbon atom. This is because helium has two protons and two neutrons in its nucleus, while carbon has six protons and six neutrons. The atomic mass of helium is approximately 4 atomic mass units, while the atomic mass of carbon is approximately 12 atomic mass units.
Electrons are the particles of an atom that have little mass compared to protons and neutrons. Electrons are around 1836 times lighter than protons and neutrons.
All matter is made of of atoms. Atoms can be bonded together to make molecules. For example, The molecule H2O is made up of 2 hydrogen and 1 oxygen. Atoms can be charged as anions or cations. In molecules there is more than 1 atom held together by a chemical bond. Molecules are neutral. Molecules may be elements or compounds. Atoms are always smaller than molecules. Molecules are always larger than atoms. Atoms are always lighter than molecule. Molecules are always heavier than atoms.
The haemoglobin molecule, because it has an Iron atom at its core, will carry four oxygen (O2) molecules, per trip, from the capillaries in the lungs to capillaries elsewhere, where the O2 is released into all of these tissues, thereby enabling cellular O2 requiring processes..
Mass of C-12 atom = 12 amu mass of C-12 atom = am So atomic mass of A = 4 amu source ; www.examville.com
The electrons form bonds with other atom's electrons to form molecules.
