Atomic Structure and Quantum Numbers Practice Quiz…

Q: According to Bohr's theory, what orbits the nucleus?

Electrons — Electrons revolve around the nucleus in orbits, as described by Bohr's theory.

Q: What happens to an atom if an electron is completely removed?

It becomes ionized — Removing an electron ionizes the atom, giving it a net positive charge.

Q: Which quantum number specifies the energy level of an electron?

Principal Quantum Number (n) — The principal quantum number (n) defines the energy level.

Q: What shape does an 'S' orbital have?

Spherical — An 'S' orbital has a spherical shape.

Q: Which quantum number indicates the shape of the orbital?

Angular Momentum Quantum Number (l) — The angular momentum quantum number (l) indicates the shape of the orbital.

Q: For l=1, how many possible values are there for the magnetic quantum number (m_l)?

3 — For l=1, m_l can be -1, 0, or +1, representing three P orbitals.

Q: What does the spin quantum number (m_s) indicate?

The direction of electron spin — The spin quantum number (m_s) indicates the direction of electron spin (up or down).

Q: What does the Pauli Exclusion Principle state?

No two electrons in an atom can have the same set of four quantum numbers. — The Pauli Exclusion Principle dictates that no two electrons in an atom can share the same set of all four quantum numbers.

Q: What is the outermost shell in elements like carbon, silicon, and germanium?

Contains four valence electrons — The outermost shell of these elements contains four valence electrons.

Q: How are electrons arranged in shells?

K, L, M, N, and so on — Electrons are arranged in shells labeled K, L, M, N, etc.
