What are the differences between the 2s orbital and the 1s orbital of hydrogen? How are they similar? (Select all that apply.)
1. The 2s orbital is shaped like dumbbells, whereas the 1s orbital is spherical.
2. The 2s orbital is more oblong than the 1s orbital.
3. The 2s orbital is larger than the 1s orbital.
4. The 2s orbital is smaller than the 1s orbital.
5. The 2s orbital is similar in shape to the 1s orbital.
6. The 2s orbital is the same size as the 1s orbital.
Grade 10 Quantum Physics and the Atom
How does the energy of a principal energy level depend on the value of n? Does a higher value of n mean a higher or lower energy?
1. The lower the value of the principal energy level, n, the higher the energy of the principal energy level.
2. The higher the value of the principal energy level, n, the higher the energy of the principal energy level.
3. The lower the value of the principal energy level, n, the lower the energy of the principal energy level.
4. The higher the value of the principal energy level, n, the lower the energy of the principal energy level.
