What kind of particles is electromagnetic radiation composed?
Electromagnetic radiation is composed of massless particles called photons. Photons have both wave-like and particle-like properties and travel through space at the speed of light.
Daltons atomic therory?
Dalton's atomic theory, proposed by John Dalton in the early 19th century, stated that all matter is composed of indivisible particles called atoms. He also proposed that atoms of the same element are identical in size, mass, and other properties, while atoms of different elements have different properties. Dalton's theory laid the foundation for modern chemistry and our understanding of the behavior of matter at the atomic level.
What was the name of the scientist that first postulated the theory of atomic structure?
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.
What are families of elements with similar chemical properties called?
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.
What is the particles of water called?
The particles of water are called molecules, composed of two hydrogen atoms and one oxygen atom.
What elements extremely small particles called?
All elements are composed of extremely small particles called atoms. Atoms are composed of protons, neutrons, and electrons.
What is only composed of single particles called atoms?
Elements are composed of only one type of atom. There are about 90 or so naturally occurring elements.
What are composed elements combined in a specific ratio called?
what consists of elements combined in a specific ratio?
What is a mixture in which different particals cannot be seen?
This is called homogeneous.
What are the elements which make your hair?
Hair is composed mostly of a protein called keratin. Like all proteins, keratin is composed mainly of the elements carbon, hydrogen, oxygen, and nitrogen.
All elements are composed of extremely small particles called?
Fermion
Who said that each element is composed of extremely small particles called atoms?
Someone Rutherford.
What are elements called that make up a star?
Stars are composed mostly of hydrogen and helium.
Why water is called a compoud and air amixture?
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.
What is composed of thin fibrous elements that form a framework for the cell?
The cytoskeleton is composed of thin fibrous elements like microfilaments, intermediate filaments, and microtubules that provide a framework for the cell and help maintain its shape and structure.
Which model of light states that light is composed of millions of particals?
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.
Is all elements composed atoms?
All matter, such as solids, liquids and gases, is composed of atoms. Any material that is composed of only one type of atom is called a chemical element.
