an element's identity was determined by its atomic number, the amount of positive charge in the very small core nucleus that also contained almost all of the atom's mass. The light electrons were held in orbits by electrostaticattractionto the positive...
Magic number, in physics, in the shell models of both atomic and nuclear structure, any of a series of numbers that connote stable structure. The magic numbers for atoms are 2, 10, 18, 36, 54, and 86, corresponding to the total number of electrons in fil
Atomic number, the number of a chemical element in the periodic system, whereby the elements are arranged in order of increasing number of protons in the nucleus. Accordingly, the number of protons, which is always equal to the number of electrons in a n

define valency the combining capacity of an atom is known as its valency. the number of bonds that an atom can form as part of a compound is expressed by the valency of the element. we all know how electrons in an atom are arranged in shells/orbitals. valence electrons are those ...
The symbol Z is given to that atomic number, which is also the number of electrons in the atom and determines its chemical properties. Computer Exercise 2.A describes the program ELEMENTS, which helps find atomic numbers, symbols, and names of elements in the periodic table. Generally, the ...
