Chemistry

3. Atom that gains electrons and becomes more negative
4. identity of substance changes. Products have different properties
6. low kinetic energy, particles move around but still close together; fixed volume but variable shape
13. a chemical element that readily gains/loses electrons to form negative or positive ions
14. measure of how easily an element will combine with other elements to form compounds
15. process in which one or more different substances are changed into one or more new substances by the reorganization of their atoms
16. the smallest particle of an element or matter; not visible to the naked eye
17. low kinetic energy, particles vibrate but cannot move around; Fixed shape and volume
18. centrally located; affected by protons and neurons present
19. formed when electrons (e-) are shared between 2 nonmetals, there are 2 types
20. Central portion of an atom
22. atoms of the same element with different masses

1. very high kinetic energy, collision with enough energy to break into charged particles (+/-)
2. most atoms form bonds to have 8 valence electrons in their outermost shell
4. atom that loses electrons and becomes more positive
5. formed when electrons (e-) are transferred from a metal to a non-metal ion
7. amount of matter per unit volume
8. can be observed without changing the identity of the substance
9. measure of how closely an atom can hold a shared electron to its cloud/orbital
10. high kinetic energy, particles separate and move throughout container; variable shape and volume
11. metals underneath the staircase of the Periodic Table
12. distance from the nucleus to the outermost electron orbital
13. the largest classification on the periodic table
21. amount of space an object takes up
