Rules of Atomic Structure

Question	Answer
What is the Atomic Number?	The number of protons
What is the maximum amount of electrons that can go on the first energy level?	2 electrons
True of False: You still draw on energy levels that have no electrons on	False: We only draw energy levels that have electrons on
Electrons fill energy levels from: Those closest to the nucleus out/Those furthest away from the nucleus in?	Those closest to the nucleus out
Relative Atomic Mass is?	Number of protons + Number of neutrons
The number of protons is the same as...	The number of electrons
The fewer the subatomic particles.. A) The lighter the atom B) The heavier the atom C) It makes no difference	A) The fewer subatomic particles in an atom, the lighter it is
The second and third energy levels have a maximum of how many electrons?	8 electrons
The period (row) an element is on tells us...	How many energy levels that element has
The group (column) an element is on tells us...	How many electrons are on the outer energy level
Isotopes are...	Different versions of the same type of atom. They have different atomic masses due to a different number of neutrons
Do isotopes react chemically in the same way? If so, why?	Yes they do. This is because it is the electrons that control reactivity not the number of neutrons
True or false: Physical properties in isotopes do not change	False: Melting point and density etc. will change because of the different number of particles in the atom
