Definition of Engineering Ethics are given Below: It is the study of the moral issues and decision confronting individuals and organizations involved in engineering. The study of related questions about moral conduct, character, ideals, and relationships of people and organizations involved in technological development. It is usually the response to specific problems that prods us to make the world better. Character, general ideals and relationships are equally important in approaching engineering ethics.

Definition of Ethics: The behavior that you expect and will accept form one another is called ethics. Basic Concepts of Ethics: Responsibility Accountability Liability Due Process Responsibility: Responsibility is a key element of ethical action. Responsibility means that you accept the potential costs, duties, and obligations for the decisions you make. Accountability: Accountability is a feature of systems and social institutions. It means that mechanism are in place to determine who took responsible action, who is responsible. System and institutions in which it is impossible to find out who took what action are inherently incapable of ethical analysis or ethical action. Liability: Liability extends the concept of responsibility further to re area of laws. Liability is the feature of political systems in which a body of laes is in place that permits individuals to recover the damages done to them by other actors, systems. or organizations. Due Process: Due Process is a rel

Dalton's Atomic Theory In 1800, Dalton   postulate some theory for atom called Dalton’s atomic theory. They are given bellow: 1) All matter is made of atoms. Atoms are indivisible and indestructible. 2) All atoms of a given element are identical in mass and properties 3) Compounds are formed by a combination of two or more different kinds of atoms. 4) A chemical reaction is a rearrangement  of atoms. 

Orbit Orbital As postulated by Bohr, an orbit is a definite circular path at a definite distance from the nucleus in which the electron revolve round the nucleus. Orbits are designated by the capital letters K, L, M, N…. etc. As postulate by wave nature of an electron, an orbital is a three-dimensional region around the nucleus within which the probability of finding an electron is maximum., Orbital’s are designated by s, p, d… etc. Orbits are circular in shape. Orbital’s have different shapes. It represents the planer motion of the electron. It represents the three-dimensional motion of the electro round the nucleus. An orbit indicates an exact position of an electron in an atom. An orbital does not specify the exact position of an electron in an atom. The maximum number of electro in an orbit is equal to 2n^2, where n is the number of the orbit. An orbital cannot acco

Emission Spectrum: According to plank’s theory of radiation, energy is radiated or absorbed by a body discontinuously in a definite fundamental unit or in an integral multiple of the fundamental unit. This unit of energy was called by plank quantum.  The emission spectrum of a chemical element or chemical compound is the spectrum of frequencies of electromagnetic radiation emitted by the element's atoms or the compound's molecules when they are returned to a lower energy state. Each element's emission spectrum is unique. Therefore, spectroscopy can be used to identify the elements in matter of unknown composition. Similarly, the emission spectra of molecules can be used in chemical analysis of substances. Look at  the given Image, it is emission spectrum of Hydrogen:

Nuclide:  A Nuclide is a particular nucleus characterized by a defined atomic number and mass number. There are particular types of Nuclides. They are: ·          Isotopes ·          Isobars ·          Isotones Isotopes: The atoms having same atomic number but different atomic mass number are called Isotope. Isobar:  Nuclides having the same mass number but having the different Proton/Atomic number are called Isobar.   Isotones: Atoms of different elements having different mass number and different atomic number but same neutron number are called Isotones.
