Contains atoms with the same atomic number
WebAtomic Number, Isotopes and Isobars - Atomic number of an element is the total number of protons present in that element, Mass number is the sum of the number of protons and neutrons of that element. The atoms having the same atomic number but different mass number are called Isotopes. To Learn more about the Atomic Number, … WebOxygen is a chemical element with atomic number 8 which means there are 8 protons in its nucleus. Total number of protons in the nucleus is called the atomic number of the atom and is given the symbol Z. The total electrical charge of the nucleus is therefore +Ze, where e (elementary charge) equals to 1,602 x 10-19 coulombs.
