Atomic Structure Notes
• The smallest part of a chemical element that has all the properties of that element is the atom.
• Everything in our world is made up of electrons, protons, and neutrons.
Practice
Nucleus • The nucleus is found in the center of the atom.
• It consists of protons and neutrons which are almost the same size because of the energy forces that act on them.
• The mass of the atom is made up of the mass of the proton and the neutron.
Nucleus:Protons & Neutrons
entire
if an atom was the size of a football stadium, then a proton would still be smaller than a marble.
Protons• All protons are exactly the
same and are found inside atoms. They have a positive charge
• Different atoms have different numbers of protons; what makes an atom be a helium or a gold atom depends on how many protons it has.
• The mass of the proton is equal to 1 atomic mass unit (amu)
an atom has equal numbers of protons
And electrons
Neutrons
• The neutron is a sub-atomic particle of the atom and is found in all elements except hydrogen. It has a neutral charge.
• The neutron and the proton make up the mass of the atom.
• Without the neutron, the protons would push away from each other.
Electrons• Electrons are found in clouds that
surround the nucleus of an atom. They have a negative charge
• Those clouds are specific distances away from the nucleus and are organized into shells.
• Because electrons move so quickly, it is impossible to see where they are at a specific moment in time.
