Periodicity Vocab Quiz Honors Chem 2023
Across
- 3. one-half the distance between the nuclei of identical atoms that are bonded together; aka: size of an atom
- 6. First man to attempt to organize elements; created the "Law of Octaves"
- 7. An atom or group of atoms that has a positive or negative charge due to losing or gaining electrons
- 9. Group 1, 1 valence electron, very reactive, soft, silver, shiny, low density metals and are also less reactive
- 11. an ion with a negative charge due to gaining electrons
- 12. States that atoms lose, gain or share electrons in order to acquire a full set of eight valence electrons
- 16. Group 2, 2 valence electrons, harder than the alkali metals
- 19. Elements that have properties of both metals and non-metals, the stair-step on the periodic table.
- 21. Groups 1,2,13-18
- 22. Vertical column in the periodic table
- 23. Groups 3-12, 1-2 valence electrons, less reactive than alkaline-earth metals, shiny, good conductor of thermal energy and electrical current, high density metals
- 24. A horizontal row of elements in the periodic table
- 25. when the elements are arranged in order of increasing atomic number, there is a periodic repetition of their physical and chemical properties chemical properties
- 26. Part of the inner transition metals following lanthanum in the periodic table, in which the 4f orbitals are being filled
Down
- 1. group 18 gases, have 8 valence electrons and are stable and non-reactive
- 2. Arranged the periodic table by atomic number instead of mass number
- 4. The amount of energy required to remove an electron from an atom
- 5. "Father of the modern periodic table"; predicted properties of undiscovered elements and organized
- 8. transition metals; groups 3-12 including f-block
- 10. Elements that are good conductors of electric current and heat, are malleable and ductile. On left side of periodic table
- 13. an ion with a positive charge due to losing electrons
- 14. A measure of the ability of an atom in a chemical compound to attract electrons
- 15. Part of the inner transition metals following actinium in the periodic table, in which the 5f orbitals are being filled
- 17. Group 17, 7 valence electrons, most reactive non-metals;also known as "halides"
- 18. Elements that are poor conductors of heat and electric current, on right side of the periodic table.
- 20. Table by increasing atomic mass
- 27. The ease and speed with which an element combines, or reacts, with other elements and compounds.
