Light is composed of particles called photons.

Families of elements with similar chemical properties are called "groups" or "families" on the periodic table. Elements within the same group typically have the same number of valence electrons, which gives them similar reactivity and chemical properties.
The scientist who first postulated the theory of atomic structure was John Dalton. He proposed his atomic theory in the early 19th century, suggesting that elements are composed of indivisible particles called atoms.
In the 1800s John Dalton did some experiments and these are some of his magnificent work: * all elements are composed of atoms. atoms can not be divided or destroyed * atoms of the same element are alike * .atoms of different elements are not alike * the atoms of two or more elements can join together to form compounds
All elements are composed of extremely small particles called atoms. Atoms are composed of protons, neutrons, and electrons.
The term for a molecule composed of two or more different elements is called a compound.
what consists of elements combined in a specific ratio?
Elements are composed of only one type of atom. There are about 90 or so naturally occurring elements.
This is called homogeneous.
Hair is composed mostly of a protein called keratin. Like all proteins, keratin is composed mainly of the elements carbon, hydrogen, oxygen, and nitrogen.
Fermion
Someone Rutherford.
Stars are composed mostly of hydrogen and helium.
Water is composed of two elements - Oxygen and Hydrogen. Air is composed of individual elements (mainly Oxygen & Nitrogen and other trace gasses) in individual atoms.
The framework of a cell in the cytoplasm is composed of thin fibrous elements. This network is called the cytoskeleton.
The particle model of light, also known as the photon model, describes light as composed of individual particles called photons. These photons have energy and momentum, and collectively give rise to the properties of light such as reflection, refraction, and interference.
