Feb 03, 2016 · Atomic number = number of protons (which, for neutral atoms, is equal to the number of electrons). Atomic symbol allows us to find the atomic number because you can just look it up on the periodic table. Atomic mass = number of protons + number of neutrons. Solutions for the Protons, Neutrons, and Electrons Practice Worksheet:

This approach proved incorrect, as it would have placed some elements in a family with dissimilar properties. Henry Mosley the table rearranged the table on the basis of the atomic numbers of the elements. I accordance with Mosley’s revision, the periodic law states: the properties of the elements are periodic functions of their atomic numbers.

To find the number of neutrons, subtract the atomic number from the atomic mass: Example for carbon: Atomic mass: 12 (rounded) Number of neutrons: 12 – 6 = 6. To find the number of electrons, look at the atomic number: Example for carbon: Atomic number: 6 Number of electrons: 6 *Complete the table for the elements with atomic numbers 1-10.
Atomic Number of Elements in Periodic Table
A periodic table is a horizontal and vertical arrangement of elements according to their atomic numbers. This table was successfully arranged in 1913 by the British scientist Henry Moseley from the previous work of the Russian Scientist Dmitri Mendeleev.
