Answers

A1. Spin

Because spin is a fundamental property of a qubit that defines its quantum state and allows for entanglement and superposition.

A2. Square of the amplitude of the wavefunction

Because the square of the amplitude of the wavefunction provides the probability density of finding a particle in a particular location, which is consistent with the probabilistic nature of quantum mechanics.

A3. Louis de Broglie

Because Louis de Broglie proposed that particles, including electrons, can exhibit wave-like behavior and have both particle and wave properties.

A4. Planck's constant

Heisenberg's uncertainty principle was formulated in 1927 by physicist Werner Heisenberg, fundamentally demonstrating that the more precisely one measures a particle's position, the less precisely its momentum can be known, with Planck's constant setting this limit.

A5. Energy

Because electrons in an atom can only have certain levels of energy, and these energy levels are quantized and discrete.

A6. 1/2

Electrons inherently possess a property called spin, which was introduced in quantum mechanics in the early 20th century to explain atomic spectral lines, and their spin quantum number is always 1/2, indicating they are fermions subject to the Pauli exclusion principle.
