The results of the experiment show that each element has a unique integer equal to the number of positive charges in the nucleus of that element. He named that number the order of the atoms.<\/p>\n\n\n\n Thus, the number of positive charges present in the nucleus of an element is called the atomic number of that element. The atomic number<\/a> of the element is expressed by \u2018Z\u2019.<\/p>\n\n\n\n This number is equal to the serial number of the periodic table. We know that protons are located in the nucleus of an atom as a positive charge. That is the total number of protons in the atomic number.<\/p>\n\n\n\n The atom is overall charge neutral. Therefore, the number of negatively charged electrons orbiting in its orbit is equal to the number of positively charged protons in the nucleus.<\/p>\n\n\n\n Atomic number (Z) = Number of charges in the nucleus (p)<\/p>\n\n\n\n |
