Atomic Number - The number of protons in the atom of an element is called the atomic number of the element. For example - The atomic number of sodium (11 N a) is 11 as it has 11 protons in the …

Isotopes are elements with the same atomic number but distinct mass numbers. Isobars are elements with various atomic numbers but the same mass number. An example of two isotopes and isobars is …

For example, 6C12, 6C13, 6C14 are the three isotopes of carbon. They have same atomic number but different mass number due to difference in the number of neutrons.

EAN stands for effective atomic number. It is used to check the stability of metal in coordination complex.

Atomic Mass Examples For carbon, the atomic mass is 12.011; most carbon atoms hold 6 protons and 6 neutrons. Moving ahead, the atomic mass of hydrogen is 1.0079. Here, hydrogen (with atomic …

Example: Protons + Neutrons = Nucleus = Mass number 6 + 6 = 12 iii)Isotopes: Isotopes are atoms of the same element which have different mass number but same atomic number. (iv)Isobars: Isobars …
