Quantum levels and electron configurations?

Acceptable values of l? Acceptable values of m? ms?In summary, the conversation involves discussing the construction of the periodic table with aliens from another universe who have different physical laws governing the properties of atoms. The rules include having the same rules for n and l, only allowing specific values for ml, and only allowing one electron per orbital. The maximum number of electrons held in each quantum level for n=1 through n=6 is determined, as well as the electron configurations for elements from Carbon to Vanadium. The first four alien halogen elements are also discussed, with a focus on determining acceptable values for n, l, m, and ms for each quantum level.

I can't do this problem at all, can anyone help? Thanks.


During a trip to Roswell, New Mexico, you find yourself at a cocktail party
with aliens from another universe. You are at a loss for conversation so you offer to
reconstruct the periodic table from memory (chemistry being the most exciting thing you
can think of). The aliens are stupefied at your choice of conversation, but inform you that
in their universe, certain key rules governing the properties of atoms are different. Not
wishing to offend your charming hosts, you naturally take their physical laws into
consideration. They are:

• We have the same rules for n and l
• The only allowed values for ml are from −2l to +2l
• Only one value is allowed for ms , that is, each orbital may hold only 1 electron.
• We have the same rule for orbital energies (i.e. 4s lower in energy than 3d, etc.)

Use the rules above to answer the following questions:

a. What is the maximum number of electrons held in each alien quantum
level, n, for n = 1 through n = 6?

b. List all the electron configurations for the alien version of the elements
from Carbon through Vanadium. Assume each element still has the same number
of electrons.

c. What are the first 4 alien halogen elements?

Try to list all possible combinations of quantum numbers using these rule.

Start with n=1 - what are acceptable values of l? For each n/l pair - what are acceptable values of m? ms?

Then move to n=2.

I am fascinated by the concept of different physical laws in other universes and how they can affect the properties of atoms. The rules provided by the aliens offer a unique perspective on quantum levels and electron configurations.

To answer the first question, the maximum number of electrons for each quantum level can be determined by the formula 2n², where n is the quantum level. Using this formula, the maximum number of electrons for n = 1 through n = 6 are 2, 8, 18, 32, 50, and 72, respectively. This is different from our universe where the maximum number of electrons for n = 1 through n = 6 are 2, 8, 18, 32, 32, and 18.

Moving on to the second question, we can use the rules provided by the aliens to determine the electron configurations for the elements from Carbon (Z=6) to Vanadium (Z=23). For Carbon, the electron configuration would be 1s² 2s² 2p². For Nitrogen (Z=7), it would be 1s² 2s² 2p³ and so on. The full list of electron configurations for these elements would be:

Carbon: 1s² 2s² 2p²
Nitrogen: 1s² 2s² 2p³
Oxygen: 1s² 2s² 2p⁴
Fluorine: 1s² 2s² 2p⁵
Neon: 1s² 2s² 2p⁶
Sodium: 1s² 2s² 2p⁶ 3s¹
Magnesium: 1s² 2s² 2p⁶ 3s²
Aluminum: 1s² 2s² 2p⁶ 3s² 3p¹
Silicon: 1s² 2s² 2p⁶ 3s² 3p²
Phosphorus: 1s² 2s² 2p⁶ 3s² 3p³
Sulfur: 1s² 2s² 2p⁶ 3s² 3p⁴
Chlorine: 1s² 2
 

1. What are quantum levels and how are they related to electron configurations?

Quantum levels refer to the specific energy levels that an electron can occupy within an atom. These levels are determined by the electron's distance from the nucleus and are represented by the quantum numbers. Electron configurations, on the other hand, describe the arrangement of electrons within an atom's energy levels.

2. How many quantum levels are there in an atom?

The number of quantum levels in an atom depends on the element and its atomic structure. Generally, the number of quantum levels is equal to the atom's period number on the periodic table. For example, a hydrogen atom has one quantum level, while an oxygen atom has two.

3. What is the significance of electron configurations in chemistry?

Electron configurations play a crucial role in determining an atom's chemical properties. They determine the atom's reactivity and ability to form chemical bonds, as well as its overall stability. The arrangement of electrons in an atom's energy levels also affects its physical properties, such as melting and boiling points.

4. How do you determine the electron configuration of an atom?

The electron configuration of an atom can be determined by following the Aufbau principle, which states that electrons fill the lowest energy levels first before moving to higher levels. The specific electron configuration of an atom can also be found by using the periodic table and Hund's rule.

5. Can electron configurations change?

Yes, electron configurations can change through various processes such as ionization, where an atom gains or loses electrons, and excitation, where an electron is promoted to a higher energy level. These changes can occur due to external factors such as temperature or the presence of other atoms.
