Periodic Table
Across
- 1. (known as group IA) a family of the Periodic table that has properties such as being very reactive, having one loosely bound valence electron, and being shiny
- 5. Father of the Periodic Table
- 8. A family of the Periodic table that are brittle solids and gain electrons easily
- 9. a family of the Periodic table with properties such as being fairly unreactive, having high melting and boiling points, and being good conductors of electricity
- 10. A stable subatomic particle that occurs in all atomic nuclei with a positive charge equal in magnitude to the unit of a electron charge
- 11. Vertical columns, and elements in these often have similar properties structures, and bonds
- 13. A family of the Periodic table that contains elements with the properties of having seven valence electrons, being highly reactive, and having very high electronegativitity
- 15. An element's most common name
- 17. (known as group IIA) a family of the Periodic table that has properties including low electron affinities, two electrons in the outer shell, and being quite reactive
- 18. A family of the Periodic table which has properties such as being radioactive, being highly electropositive, and being very dense with a distinctive structure
- 19. an abbreviation taken from the element's English or Latin name that is one or two letters
- 21. A family of the Periodic table that possess the characteristics of both Metals and Nonmetals
Down
- 2. A number that is equal to the number of protons in the nucleus and determines the place of an elements on the Periodic table
- 3. A family of the Periodic table that have properties of being fairly nonreactive, having a complete valence shell, and a having a low boiling point
- 4. An array of chemical elements in order of increasing atomic number
- 6. Recurring pattern in element's properties when arranged in order of increasing atomic number
- 7. A family of the Periodic table that contains properties like having high melting and boiling points, being silver colored, and being very reactive
- 12. A family of the Periodic table which has properties such as being solid at room temperature
- 14. A horizontal row of the Periodic table, and in this row elements have the same energy level
- 16. A neutral subatomic particle that is an essential part of almost every atomic nuclei and has no electrical charge
- 17. Expressed in atomic units and is the mass of an atom of an chemical element
- 20. A stable subatomic particle with charge of negative electricity
