Study Notes
Atomic Mass Number
- Represents the total number of protons and neutrons in an atom's nucleus.
- Determines the mass of an atom relative to others and is expressed in atomic mass units (amu).
M Shell Electron Capacity
- The M shell, also known as the third principal energy level, can hold up to 18 electrons.
- Follows the formula 2n², where n is the principal quantum number (n=3 for M shell).
Modern Atomic Structure
- Comprised of a nucleus containing protons and neutrons, surrounded by electron orbitals or shells.
- Electrons are arranged in energy levels, influenced by quantum mechanics.
Fundamental Particle by Sir J.J. Thomson
- Discovered the electron, which is a negatively charged subatomic particle.
- His work in 1897 led to the understanding of atomic structure beyond the indivisible atom concept.
Octet Rule
- States that atoms tend to form compounds in ways that allow them to have eight electrons in their outermost shell.
- This rule helps explain the stability of atoms and influences their chemical behavior in bonding.
