What is the electron configuration of Silver?

Back

1s² 2s² 2p⁶ 3s² 3p⁶ 3d¹⁰ 4s² 4p⁶ 4d⁹

Front

What does the Pauli exclusion principle state?

Back

No two electrons in an atom can have the same set of four quantum numbers; electrons in the same orbital must have opposite spins.

Front

What is incorrect about an orbital diagram where both arrows in the 2p box are pointing up?

Back

In the 2p box, there should only be 1 electron in the first 2p box and one in the 2nd 2p box pointing in the same direction.

Front

Which of the following is NOT a possible pair of quantum numbers?

Back

2d is not a valid pair of quantum numbers.

Front

What is the noble-gas notation for chlorine's electron configuration?

Back

[Ar] 3s² 3p⁵

Front

Define quantum numbers.

Back

Quantum numbers are a set of numerical values that describe the unique quantum state of an electron in an atom.

Front

What are the four types of quantum numbers?

Back

Principal (n), Angular (l), Magnetic (m), and Spin (s).

Front

What does the Aufbau principle state?

Back

Electrons occupy the lowest energy orbitals first before filling higher energy levels.

Front

What is Hund's rule?

Back

Electrons will fill degenerate orbitals singly before pairing up in the same orbital.

Front

What is the maximum number of electrons in an orbital?

Back

An orbital can hold a maximum of 2 electrons.
