Atomic number - In chemistry and physics, the atomic number (Z) is the number of protons found in the nucleus of an atom. In an atom of neutral charge, the number of electrons also equals the atomic number.

Effective atomic number - Effective atomic number has two different meanings: one that is the effective nuclear charge of an atom, and one that calculates the average atomic number for a compound or mixture of materials. Both are abbreviated Zeff.

List of elements by atomic number - This is a list of chemical elements, sorted by atomic number and color coded according to type of element. Each element's name, element symbol, atomic weight (or most stable isotope), and group and period numbers on the periodic table are given.

Mass number - The mass number (A), also called atomic mass number or nucleon number, is the number of protons plus the number of neutrons in an atomic nucleus. The mass number is unique for each isotope of an element and is written either after the element name or as a ...

Atomic Structure and the Pascal Triangle - Explores a connection between electron shell numbers on the one hand and pyramidal, tetrahedral and triangular numbers on the other.

FUSE Atomic Data Page - Provides atomic data (statistical weights, transition probablilities, and oscillator strengths) for elements Hydrogen (including Deuterium) up to Ge (atomic number 32), plus Tables of UV lines sorted by wavelength.

About Big Numbers - Explores the world of big numbers, from thousand to googol. Identifies what objects in the universe, atoms to large scale structures, match these numbers.
