Chap. 3 & 4 Flashcard

Front

What does the spin quantum number describe?

Back

Direction of the electron spin

Front

According to the Aufbau's principle, where should the first electron go in electron configurations?

Back

1s

Front

As the energy level goes higher, what happens to the electrons?

Back

They are farther from the nucleus.

Front

What guideline is violated in the following orbital diagrams: Hund’s rule or the Pauli exclusion principle?

Back

Hund's rule

Front

How many atoms of carbon are in 6.00g of carbon?

Back

3.01x10^23 atoms C

Front

What is the Pauli exclusion principle?

Back

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

Front

What is Hund's rule?

Back

Electrons will fill degenerate orbitals singly before pairing up.

Front

What is the significance of the Aufbau principle in electron configuration?

Back

It states that electrons occupy the lowest energy orbitals first.

Front

Define the term 'orbital' in the context of atomic structure.

Back

An orbital is a region in an atom where there is a high probability of finding electrons.

Front

What does the principal quantum number indicate?

Back

The principal quantum number indicates the energy level and size of the orbital.
