The average atomic mass grams shown on the periodic table for each element is also the mass of?
one mole of atoms of the element
For every element, the atomic number, symbol of the element and atomic mass is listed. And on most periodic tables, the state of matter. If you know how, you can distinguish how many protons, neutrons and electrons an element has. The atomic number (number on top of the letter) is the number of protons, and also the number of electrons. If you subtract the atomic mass (the number on the bottom of the symbol) from…
Each box on the periodic table has two numbers in it. The number on top is the atomic number. The number on bottom is the relative atomic mass. The atomic number is the number of protons each atom of the element contains. The relative atomic mass is the mass in grams of one mole of the element with the relative percentages of the isotopes taken into consideration.
The atomic number of carbon (C) is 6. The atomic weight of C is 12.011 grams per mole. The atomic number of an element is the number of protons in the element. Carbon has 6 protons and therefore has an atomic number of 6 (See the Related Links below this answer for a periodic table with more information about this element)
