2023-24 Physical Science Chapter 3 Sections 3.2 and 3.3

Classical physics is still fine for explaining the motion and energy of atomic and subatomic particles.

• True

• False

The Bohr atomic model suggests that electrons move

• in a flat ring around a massive, positively charged center (nucleus)

• only in distinct, spherical orbits at fixed distances from the nucleus

• randomly around the nucleus

• rapidly throughout a uniform, positively charged matrix

The Bohr atomic model was correct in every way.

• True

• False

The new branch of modern atomic science that began in the 20th century is known as

• Super Atomic Laws

• Relativity

• Plum Pudding Model

• Quantum Mechanics

• Mike and the Mechanics

In Quantum Mechanics, could precisely pinpoint where an electron would be at any point in time.

• True

• False

In the quantum mechanical model of the atom, the spherical orbits of the Bohr model were replaced by ________________.

• Electron Arcs

• Orbitals

• Neutron Kinetics

• Quarks

oddly shaped regions in atoms where electrons are likely to be found

• Orbitals

• Atomic Spheres

• Atomic Spaghetti

• Squares

The quantum mechanical model is currently still the primary model being used by physicists and chemists today.

• True

• False

The key factor that drove the development of new atomic models is

• workability

• ease of changeability

• ease of measurement

• understanability

The Bohr atomic model is still used today even though it is not entirely accurate.

• True

• False
