2. The number of protons in the nucleus of an electrically neutral atom | Constitutes it's atomic number. |
3. The atomic weight of an electrically neutral atom | Approximately equals the number of neutrons plus the number of protons. |
4. When an atom has a net positive charge, we call it | A cation. |
5. A carbon atom can have | More than one isotope. |
6. An element who's molecules contain two atoms | Is diatomic. |
7. A monatomic compound | Cannot exist; it's a contradiction in terms. |
8. Ionization can sometimes cause | The conductivity of a substance to improve. |
9. Of the following substances, which one is the best electrical conductor | Silver |
10. Dry air is normally a poor conductor of electricity because | the molecules are far apart. |
11. If we place an EMF of 2 V across a component whose resistance equals 1 ohm, how much current will flow through the component? | 2 A |
12. If we double the potential difference in the scenario of Question 11 ( If we place an EMF of 2 V resistance 1 ohm, how much current will flow) but don't change the components resistance, the current the current through the component will | double |
13. In electronics, the term hole refers to a place in an atom where | an electron would normally exist, but doesn't. |
