All Flashcards
Define Atomic Number.
The unique number of protons in an atom's nucleus, defining the element's identity.
What are isotopes?
Atoms of the same element with the same number of protons but different numbers of neutrons.
Define valence electrons.
Electrons in the outermost shell of an atom that participate in chemical bonds.
What is a cation?
A positive ion formed when an atom loses electrons.
What is an anion?
A negative ion formed when an atom gains electrons.
Define Quantization in the context of the Bohr model.
The concept that electron orbit circumference must be an integer multiple of the electron's de Broglie wavelength, leading to specific allowed energy states.
Label the components of the Carbon-12 nucleus.
Protons: 6, Neutrons: 6
In a Bohr model diagram, what do the concentric circles represent?
Energy levels or electron shells.
