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.

An atom is comprised of a central portion called a nucleus that contains protons and neutrons. Electrons orbit the nucleus and are typically found in a one-to-one ratio with protons. Different stable atomic configurations are called elements. Hydrogen is unique in having one proton, one electron and

The modern atomic theory is a theory that all matter is composed of tiny particles called atoms. This theory is used in physics and chemistry to explain the behavior of all matter.

Family structural theory was developed by Salvador Minuchin and focuses on identifying the strengths of a family system in order to reduce dysfunctional patterns of interaction. This fits within the larger field of family systems theory, in which a family is seen as a complex set of interactions and

The oxygen atom has two energy levels, with two electrons in the s orbital of the first, two electrons in the s orbital of the second and four electrons in the p orbital of the second. It has eight electrons, eight protons and eight neutrons.

Structural-functional theory, or structural functionalism, views society as a system of functional and interconnected units that work together as a whole to produce a state of stability and order. Because of their interconnectedness, the individual units of society can affect each other. If one of t

An atomic number represents the amount of protons that an element consists of in its nucleus. It is the identifying number that is unique to one atom of the specific element.

Bohr's atomic theory suggests that atoms have a positively charged nucleus that is orbited by electrons that move in circles. These electrons move in specific, distinct orbital levels. This theory has since been made obsolete but has had a lasting impact on the understanding of atomic structure and

The Lewis dot structure for P, the chemical symbol for a single atom of phosphorous, is written with a P surrounded by two dots together on one side and three single dots on the three remaining sides. Each dot represents a valence electron.

Dalton's atomic theory states four critical truths about atoms: firstly, everything is made up of atoms and atoms cannot be destroyed. Secondly, all atoms within a single element are identical. Thirdly, compounds are formed from two or more different kinds of atoms. Finally, chemical reactions rearr
