What is the difference between atomic mass and mass number?

<p>Atomic mass is the average mass of all the atoms of a particular element, taking into account the relative abundance of its isotopes. Mass number is the total number of protons and neutrons in the nucleus of a specific atom.</p> Signup and view all the answers

What is the significance of the Heisenberg uncertainty principle?

<p>The Heisenberg uncertainty principle states that it is impossible to simultaneously determine both an electron's position and its momentum with absolute certainty. The more precisely we know one, the less precisely we can know the other.</p> Signup and view all the answers

What is a quantum number, and what are the four types of quantum numbers?

<p>A quantum number is a set of numbers that describe the properties of an electron in an atom. The four types of quantum numbers are: 1. Principal quantum number (n): describes the main energy level or shell. 2. Azimuthal quantum number (l): describes the shape of the orbital and its angular momentum. 3. Magnetic quantum number (ml): describes the spatial orientation of the orbital in space. 4. Spin quantum number (ms): describes the intrinsic angular momentum or spin of the electron.</p> Signup and view all the answers

Describe Rutherford's gold foil experiment and its major conclusions.

<p>Rutherford directed a beam of alpha particles at a thin sheet of gold foil. Most of the particles passed through undeflected, but a few were deflected at large angles, and some even bounced back. This led him to conclude that the atom's positive charge is concentrated in a small, dense nucleus, while the rest of the atom is mostly empty space.</p> Signup and view all the answers

What is the photoelectric effect and how does it demonstrate the quantized nature of light?

<p>The photoelectric effect is the emission of electrons from a metal surface when light of a certain minimum frequency, called the threshold frequency, shines on it. The effect demonstrates that light is quantized, meaning it exists as packets of energy called photons. The energy of a photon must be equal to or greater than the work function of the metal to eject an electron.</p> Signup and view all the answers

Explain the difference between continuous and line spectra.

<p>A continuous spectrum contains all the wavelengths of light within a given range, as seen in a rainbow, while a line spectrum only shows specific wavelengths of light, appearing as discrete lines. Atomic spectra are line spectra, and the specific wavelengths emitted or absorbed by an atom are characteristic of that element.</p> Signup and view all the answers

What is the role of Bohr's model of the atom in explaining the line spectrum of hydrogen?

<p>Bohr's model suggested that electrons exist in specific quantized orbits around the nucleus, and transitions between these orbits involve the absorption or emission of energy in the form of light. The specific wavelengths of light emitted or absorbed by hydrogen correspond to the energy differences between these orbits, explaining its line spectrum.</p> Signup and view all the answers

What are de Broglie waves?

<p>De Broglie waves are the wave-like properties associated with matter, implying that any particle can behave like a wave. The wavelength of a wave associated with a particle is inversely proportional to its momentum.</p> Signup and view all the answers

Which of the following best describes the quantum mechanical model of the atom?

<p>A model that describes the probability of finding an electron in a particular region of space. (A)</p> Signup and view all the answers

What is the significance of electron probability distribution in the quantum mechanical model of the atom?

<p>Electron probability distribution describes the likelihood of finding an electron in a given region of space around the nucleus. It replaces the concept of fixed orbits with a more probabilistic description, acknowledging the wave-like nature of electrons.</p> Signup and view all the answers
