protons. Located in the atom’s nucleus‚ protons and neutrons are referred to as nucleons. The electrons rest outside of the nucleus at various energy levels (orbitals). Most of an atom’s mass comes from its very small nucleus‚ whose protons and neutrons each have a mass of approximately 1 u (atomic mass units). Electrons‚ on the other hand‚ have a mass of around 0.0005 u – almost negligible compared to the masses of a nucleon. Each subatomic particle carries a specific charge. Electrons are considered

Design/methodology/approach – The paper draws on the resource-based literature to assemble an integrated set of steps that evaluate a firm’s resources and competence. Findings – The paper proposes an expanded version of the VRIO model that represents resource and competence as a conditional outcome from attributes and asymmetries present in

protons in the nucleus of an atom. Nucleon or mass number (A) This is the total number of protons and neutrons in the nucleus of an atom. Note: a nucleon is a particle found in the nucleus i.e. a proton or a neutron. In general‚ if N is the neutron number of an element‚ then A=Z+N In an atom the number of protons is equal to the number of electrons. Nuclide notation A nuclide is a form of an element. If X is a given nuclide with proton number Z and nucleon number A‚ then its nuclide notation

Nuclear Chemistry Nuclear science is the study of sub-atomic particles and their function in various subjects. A nucleon is the collective name for the two components of the atomic nucleus: the neutron and the proton. Isotopes are any of the different forms of an element each having different mass numbers‚ which give the total number of nucleons. The major fundamentals of nuclear chemistry include radioactive decay‚ the nature of fission and fusion‚ and mass defect. The decomposition of the
