Periodic trends

2. Russian scientist who created the periodic table of elements
3. Horizontal classifications on the periodic table, where elements on the left have lower atomic numbers and it increases as you move right and down
5. An atom with a positive or negative charge due to the gain or loss of electrons
14. the tendancy of normal atoms to resist the loss of electrons
15. Any element in the central block of the periodic table that have a strong tendancy to form coordination compounds
16. Elements in which the inner shell is complete but the outer is not

1. a chemical element that has properties somewhere between a typical metal and nonmental
3. law a law stating that the elements, when listed in order of their atomic numbers (originally, atomic weights), fall into recurring groups, so that elements with similar properties occur at regular interval
4. The total distance from the nucleus of an atom to its outermost electron
6. very reactive non-metals that react with metal and form salts, hard to find in nature
7. Very reactive metals found in the first collumn of the periodic table
8. verticle columns on the periodic table that share similar properties
9. Positively charged ions
10. An element that is not metal
11. Elements that exist soley in gas form, and are non-reactive
12. Negatively charged ions
13. any substance that contains a high amount of eletrical and thermal conductivity. Malliable and reflective of light
17. the chemical property of an atom that describes its ability to attract electrons towards itself
