Rules of Atomic Structure
Fichas del conjunto (13)
- 1What is the Atomic Number?The number of protons
- 2What is the maximum amount of electrons that can go on the first energy level?2 electrons
- 3True of False: You still draw on energy levels that have no electrons onFalse:
We only draw energy levels that have electrons on - 4Electrons fill energy levels from: Those closest to the nucleus out/Those furthest away from the nucleus in?Those closest to the nucleus out
- 5Relative Atomic Mass is?Number of protons + Number of neutrons
- 6The number of protons is the same as...The number of electrons
- 7The fewer the subatomic particles.. A) The lighter the atom B) The heavier the atom C) It makes no differenceA)
The fewer subatomic particles in an atom, the lighter it is - 8The second and third energy levels have a maximum of how many electrons?8 electrons
- 9The period (row) an element is on tells us...How many energy levels that element has
- 10The group (column) an element is on tells us...How many electrons are on the outer energy level
- 11Isotopes are...Different versions of the same type of atom. They have different atomic masses due to a different number of neutrons
- 12Do 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
- 13True or false: Physical properties in isotopes do not changeFalse:
Melting point and density etc. will change because of the different number of particles in the atom
