2. Have the same composition throughout- evenly mixed
3. all components of a mixture are in the same phase
4. An element that is nonmalleable, nonductile, and a poor conductor of
electricity and heat
5. the core of an atom, consisting of two basic subatomic particles- protons
and neutrons
6. A substance with a pH more than 7 that turns litmus paper blue
7. a chemical bond in which atoms are held together by their mutual
attraction for two electrons they share
8. Atoms of the same element that contain different numbers of neutrons
and therefore, different masses
9. An atom with a positive or negative charge due to loss or gain of
electrons
10. An element that is generally shiny, opaque, malleable, ductile, and a
good conductor of electricity and heat
11. A vertical column on the periodic table; numbered from 1 to 18
12. Exhibit both metallic and nonmetallic properties; eight elements (B, Si,
Ge, As, Sb, Te, Po, At)
13. A horizontal row on the periodic table numbered 1 through 7
14. any electron in the outermost occupied shell of an atom.
15. the electrical force of attraction that holds ions of opposite charge
together
16. the different components of a mixture are in different phases
17. a change in which a substance changes its phase or some other physical
property but not its chemical composition
18. A mixture in which the different components can be seen as individual
substances- not evenly mixed
19. A material in which atoms of different elements are chemically held to
one another
20. the study of matter and the transformations that it can undergo
21. any change in a substance that involves a rearrangement of the way its
atoms are bonded
