Periodic Table and Quantum Numbers

Flashcards covering key concepts from the periodic table and quantum numbers.

What does the 2nd Quantum Number indicate?

It suggests sublevels that exist within the principal energy level and describes the orbital's shape.

What is the maximum number of electrons that can be held in an s subshell?

An s subshell can hold a maximum of 2 electrons.

What are the possible values for the Magnetic Quantum Number (m)?

For each value of l, m can have values from -l to +l, including 0.

Define Pauli's Exclusion Principle.

No two electrons in an atom can have the same set of four quantum numbers.

What shape is associated with an s orbital?

An s orbital has a small spherical shape.

How many electrons can a p subshell hold?

A p subshell can hold a maximum of 6 electrons.

What is the atomic number of Gold (Au)?

The atomic number of Gold (Au) is 79.

What does the principal quantum number (n) indicate?

The principal quantum number (n) determines the energy and size of the orbital.

What are the shapes of the orbitals for the 3rd energy level?

The 3rd energy level has s (spherical), p (dumbbell), and d (complex shapes) orbitals.

What symbol represents the primary quantum number?

The symbol for the primary quantum number is n.

What information does the Spin Quantum Number convey?

The Spin Quantum Number (ms) describes the direction of the electron's spin and can be either +½ or -½.

What does the 3rd Quantum Number represent?

The 3rd Quantum Number represents the orientation of the orbital in 3-D space.

What is the atomic mass of Hydrogen (H)?

The atomic mass of Hydrogen (H) is approximately 1.01 u.

List the letters used to represent sublevels in quantum numbers.

The letters used are s, p, d, and f.

How many subshells can a d orbital have?

A d orbital can have 5 subshells that can hold a total of 10 electrons.

What determines the order of filling orbitals?

The order of filling orbitals follows the Aufbau principle based on energy levels.
