The atomic theory is that all matter is made up of tiny units or particles called atoms. This theory describes the characteristics, structure and behavior of atoms as well as the components that make up atoms. Furthermore, the theory states that all elements are made up of identical atoms.Continue Reading
The atomic theory is a theory in the study of chemistry that states atoms are the building blocks of matter. Atoms contain protons, neutrons and electrons. Protons, which have a positive charge, and neutrons are found in the nucleus of the atom. Electrons, which have a negative charge, orbit the nucleus.
According to the atomic theory, all elements contain atoms. The difference is the number of protons, electrons and neutrons in that atom. For instance, hydrogen contains one proton and one electron but no neutrons. Oxygen, on the other hand contains eight protons, electrons and neutrons. The difference in protons, electrons and neutrons determines the stability and the other properties of any particular element. These elements are grouped according to their atomic masses, which depend on the number of protons and neutrons in each of the atoms. Because oxygen has more protons and neutrons than hydrogen, it has a higher atomic mass.Learn more about Chemistry
Calculating the ionization energy of atoms is a simple process that requires basic knowledge of the electron configuration arrived at through Koopman's theory. Ionization energy is the energy an electron takes to detach itself from a neutral atom. Some elements have more than one ionization energy.Full Answer >
Every living and non-living component that comprises matter consists of molecules, which are formed from the chemical combination of microscopic particles known as atoms. Unlike atoms, molecules are able to transition from one state of matter into another.Full Answer >
The particle theory of matter states that all matter is made up of tiny particles, specifically atoms and molecules, and that these particles have inherent characteristics. A major part of the theory is the belief that all particles in a single pure substance are the same and are different from particles of other substances.Full Answer >
Quantum physics, also referred to as quantum mechanics, is "A theory of matter that is based on the concept of the possession of wave properties by elementary particles," according to Merriam-Webster. Quantum physics deals with the behavior of light and matter at a subatomic and atomic level.Full Answer >
