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.

__________

1. what is an atom? (p. 128)

__________

1. in the following space draw and label the atom (p.128) ( include: nucleus, protons, neutrons, and electrons)

illustration of atom:

1. in the periodic table there is one square per element. label the square (p.137)
2. refer to page 140. identify some uses for alkali metals. (complete sentence)
3. look at the graph on page 141. what element has the highest melting point? __________
4. refer to page 142. identify some common uses for transition metals.

__________

1. what is an ion? (p.185) identify an example.

__________

1. how do ions form? (p.185)__________

Explanation:

1. The basic measurement of length is the meter, volume is the liter, and mass is the kilogram.
2. Volume is the amount of space of an object.
3. Matter is anything that has mass and takes up space.
4. Everything matters because everything in the universe is made up of matter, and matter is essential for the existence and function of all things.
5. An atom is the smallest unit of an element that retains the chemical properties of that element.
6. (This requires a drawing which cannot be provided in text - but the nucleus is at the center with protons and neutrons inside it, and electrons are in orbitals around the nucleus)
7. (This requires labeling a periodic - table square which cannot be fully done in text, but it typically includes the atomic number, symbol, element name, and atomic mass)
8. Alkali metals are used in batteries, as heat - transfer agents, and in some chemical reactions.
9. (Without seeing the graph on page 141, an exact answer cannot be given. But it would be the element with the highest value on the melting - point axis of the graph)
10. Transition metals are commonly used in construction (e.g., iron in steel), in electrical wiring (e.g., copper), and in catalysis.
11. An ion is an atom or molecule that has a net electrical 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.
