The nucleus contains the majority of the mass in an atom. The nucleus contains the protons and neutrons, which each have a relative mass of 1 amu. The electrons surround the nucleus and have a relative mass of 0 amu.
Smallest atom is hydrogen Largest atom is Francium
The largest atom is francium. It is not possible to tell the largest molecule as it will be generally polymeric.
The largest atom is francium and has 87 protons and 87 electrons.
The electron is actually the smallest particle. The neutron is the largest particle, followed closely by the proton. The electron is much, much smaller.
larger than the smallest

The centre of an atom is called the nucleus. It is the largest and heaviest part of the atom. It is made of protons and neutrons, the number depending on the element in question. These are made of smaller particles, but for a basic understanding this is not required.
Cesium
no an atom is a part of a molecule.
Barium is the largest alkaline earth metal atom in terms of atomic radius.
Element hassium has the largest Atomic Mass.
which atom in a water molecule has the greatest electronegativity?
The electron is the part of the atom that accounts for electricity.
The largest atom is francium and has 87 protons and 87 electrons.
The order from smallest to largest is: atom, neutron, nucleus, molecule, head of a pin. Atoms are the smallest unit of matter, composed of a nucleus (protons and neutrons) surrounded by electrons. Neutrons are subatomic particles found within the nucleus of an atom. Nucleus is the central part of an atom containing protons and neutrons. Molecules are formed when atoms chemically bond together. The head of a pin is significantly larger compared to molecules.
