The component
This molecule contain only one atom from each component.
electrons
Neutron
The atom
Protons and Neutrons and Electrons
Electrons are the smallest component of an atom.
i am telling on ly two characteristics for each atom component- electron-it contains an unit negative charge and actively takes part in all the atomic reactions. proton-it contains the same charge as the electron does but it is positively charged.protons are present inside the nucleus. neutron-it is neutrally charged particleand present inside the nucleus.
Protons determine which element an atom is.
A molecule is composed of one or more atoms that are properly bonded to each other. If a molecule contains more than one atom, each atom is then a partial molecule as opposed to a whole molecule. Therein lies the difference.
electron
protons
the only difference is the structure or else the molecular formula and hence number of each type of atom is the same.
