Picture
true of false
The atom shown in the diagram has 4 energy levels or shells.
2. The atom shown in the diagram above has a total of 5 electron orbitals.
3. Each energy level consists of 2 or more orbitals.
4. The second energy level consists of 4 electron orbitals.
5. Some orbitals near the nucleus are spherical (s orbitals), while others are dumbbell-shaped (p orbitals). Still others, farther away from the nucleus, have other shapes.
6. Because electrons are attracted to the positively charged nucleus, the closer an electron is to the nucleus, the more potential energy it has.
7. Because the amount of energy an electron possesses is related to its distance from the nucleus, electrons that are the same distance from the nucleus have the same energy, even if they occupy different orbitals. Such electrons are said to occupy the same energy level.
8. Energy levels, which are usually drawn as circles around the nucleus, indicate an electron’s energy, while orbitals, which have a variety of three dimensional shapes, indicate an electron’s most likely location.
9. In living organisms, chemical energy is stored in high-energy electrons that are transferred from one atom to another in reactions involving oxidation and reduction.
10. Each energy level can hold a maximum of 2 electrons.
No diagram.
1. False. To determine the number of energy levels or shells, you need to count the number of electron shells in the diagram.
2. False. To determine the total number of electron orbitals, you need to count the number of individual orbitals in the diagram.
3. True. Each energy level consists of 2 or more orbitals.
4. False. The second energy level can hold a maximum of 8 electrons, which means it consists of 4 electron orbitals (s, p, d, f).
5. True. Orbitals near the nucleus can be spherical (s orbitals), dumbbell-shaped (p orbitals), or have other shapes for higher energy levels.
6. True. Electrons are attracted to the positively charged nucleus and have more potential energy when closer to the nucleus.
7. True. Electrons that are the same distance from the nucleus, even if they occupy different types of orbitals, have the same energy and are said to occupy the same energy level.
8. True. Energy levels indicate an electron's energy, while orbitals indicate an electron's most likely location. Energy levels are usually drawn as circles, while orbitals have various shapes.
9. True. In living organisms, chemical energy is stored in high-energy electrons that are transferred between atoms in oxidation and reduction reactions.
10. False. Each energy level can hold a specific number of electrons. The first energy level can hold a maximum of 2 electrons, while higher energy levels can hold more (8 in the second, 18 in the third, and so on).
