Atomic Model - Bohr Model

Flashcards covering the Bohr Atomic Model, including its components and drawing steps.

Atomic Model (Bohr Model)

A model representing an atom with a nucleus in the center and electrons orbiting in shells.

Nucleus

The central part of an atom containing protons (p⁺) and neutrons (n⁰).

Protons (p⁺)

Positively charged particles located in the nucleus of an atom; their number equals the atomic number.

Neutrons (n⁰)

Neutral particles located in the nucleus of an atom; their number is calculated as Mass number minus Atomic number.

Electrons (e⁻)

Negatively charged particles that orbit the nucleus in shells; their number equals the atomic number in a neutral atom.

Electron Shells

Concentric rings around the nucleus where electrons are placed.

Atomic Number

Represents the number of protons in an element, and also the number of electrons in a neutral atom.
