Periodic Table, Electron Configuration, History and Atom Structure
Across
- 3. Groups in the periodic table that describes similar chemical properties with other elements (ex: Halogens)
- 4. Thomson: 1904, he discovered negative charges within the atom’s and made the Plumm pudding model
- 6. 1910, he claimed that atoms have a mass consisting of Protons and Neutrons, created Rutherford model
- 8. Radius: The length from the center of the nucleus to the outermost electron shell
- 9. 1913, he stated and created the Bohr model where electrons were in electron rings with specific number of electrons in each ring
- 10. The energy required to move electrons from the electron shell
- 12. Principle: Principle states start at the lowest energy on the Aufbau diagram
- 14. Organizes the periodic table Downwards
- 15. Organizes the periodic table Across
- 16. Contains two electrons, used for electron configuration
- 18. The tendency to attract electrons to form a full electron shell
Down
- 1. Rule: Rule declares electrons must fill up other orbitals before pairing them up
- 2. Particle located outside the nucleus in shells with a negative charge
- 4. Dalton: 1803, stated atoms can't be created nor destroyed
- 5. Particle in the nucleus that has a positive charge, and determines atomic number
- 7. electrons: Electrons located on the outermost layer of the electron shell, can describe reactivity and for bonding.
- 11. Particle in the nucleus with a neutral charge, varies with isotopes
- 13. A Greek who discovered the atoms existence, states it makes up all matter
- 14. Exclusion Principle: A principle states each orbital holds 3 electrons with opposite spins
- 17. Term used where directions Ionization, Electronegativity and Atomic Radius follow on the periodic table.
