Isotopes are nuclides that have the same atomic number and are therefore the same element, but differ in the number of neutrons. The atomic number is the number on the periodic table, and is always equal to the number of protons. Electrons When you compare the masses of electrons, protons, and neutrons, what you find is that electrons have an extremely small mass, compared to either protons or neutrons.

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. " Very worthwhile. 17 In a neutral atom, the number of protons equals Negative and positive charges of equal magnitude cancel each other out. Only strontium (Sr) atoms can have 38 protons. These two forces compete, leading to various stability of nuclei. .ec_details_customer_review_date{ color:#666666; } Li-3 protons, 3 electrons, 4 neutrons. Similar charges present in electrons of atoms repel each other. . Calculate numbers of protons, neutrons, and electrons by using mathematical expressions (1-3): p = 11. n = 23 - 11 = 12. e = 11 - 0 = 11 4.
