Periodic Table
Across
- 1. Atoms of the same element that have a different number of neutrons
- 5. The bond between nonmetals
- 7. An element whose properties are intermediate between those of metals and solid nonmetals or semiconductors
- 8. elements and/or compounds that when put together are unable to react chemically
- 11. The bond between a metal and a non metal
- 13. How likely an element is to form bonds with other elements
- 15. A stable subatomic particle occurring in all atomic nuclei, with a positive electric charge equal in magnitude to that of an electron, but of opposite sign
- 16. A positively charged ion
- 18. They are reactive nonmetallic elements that form strongly acidic compounds with hydrogen from which simple salts can be made
- 20. an atom with a charge
Down
- 2. Rows across on the periodic table
- 3. Elements that are shiny good conductors and found on the left of the periodic table
- 4. Columns up and down on the periodic table
- 6. A substance that cannot be broken down into a simpler substance by ordinary chemical means
- 9. Elements that are dull brittle and often a gas at room temperature
- 10. A stable subatomic particle with a charge of negative electricity, found in all atoms and acting as the primary carrier of electricity in solids
- 12. A region of probability in which the electron can be found
- 14. A negatively charged ion
- 17. The smallest particle of an element that retains the elements properties
- 19. A subatomic particle of about the same mass as a proton but without an electric charge, present in all atomic nuclei except those of ordinary hydrogen
