Question

name _ date _ period _ the other side of science refer to the page and answer with a complete sentence. 1. the basic measurement of length _ (p.18) volume _ mass _ 2. volume is the amount of _ of an object.(p.22) 3. what is matter? (p.58) 4. explain why everything matters: 5. what is an atom? (p. 128) 6. in the following space draw and label the atom (p.128) ( include: nucleus, protons, neutrons, and electrons) illustration of atom: 7. in the periodic table there is one square per element. label the square (p.137) 8. refer to page 140. identify some uses for alkali metals. (complete sentence) 9. look at the graph on page 141. what element has the highest melting point? 10. refer to page 142. identify some common uses for transition metals. 11. what is an ion? (p.185) identify an example. 12. how do ions form? (p.185)

Explanation:

1. The basic measurement of length is the meter, of volume is the liter, and of mass is the kilogram.
2. Volume is the amount of space an object occupies.
3. Matter is anything that has mass and takes up space.
4. Everything matters because everything in the universe is made up of matter.
5. An atom is the smallest unit of an element that retains the chemical properties of that element.
6. An atom has a nucleus in the center containing protons and neutrons, with electrons orbiting around the nucleus.
7. In a periodic - table square, one can label the atomic number, symbol, element name, and atomic mass.
8. Alkali metals are used in batteries, in the production of some chemicals, and in certain types of lighting.
9. Without seeing the graph on page 141, it's impossible to determine the element with the highest melting point.
10. Transition metals are commonly used in construction (e.g., iron in steel), in electronics (e.g., copper in wiring), and in catalysis.
11. An ion is an atom or molecule that has a net electric charge due to the loss or gain of one or more electrons. For example, a sodium ion ($Na^+$) is formed when a sodium atom loses one electron.
12. Ions form when atoms gain or lose electrons to achieve a stable electron - configuration, usually a full outer shell.
