Nucleus Of An Atom
Proton Number & Nucleon Number
? All shares of an element contain the identical fare of protons.
? The proton identification number of an atom is defined as the number of protons in its nucleus. Proton number is represented by the symbol Z.
? In a neutral atom, the proton number also represents the number of electrons in orbit.
? The protons and neutrons in the nucleus of an atom are called nucleons.
? The nucleon number of an atom is defined as the total number of protons and neutrons in its nucleus.
Nucleon number is represented by the symbol A.
? Number of neutrons N in the nucleus :-
N = A - Z
? The nucleus of an atom with a particular number of protons and neutrons is called a nuclide. A nuclide is reffered to by its nucleon number, for example, atomic number 3 6 and carbon 12.
? Each type of tom has a symbol. For example, H is the symbol for hydrogen atom.
? If an atom of an element X has a nucleon number A and a proton number Z, its nuclide is repersented by the following notation :
? Isotopes of an element are atoms which have the kindred number of...If you want to get a full essay, score it on our website: Ordercustompaper.com
