1) Coronium, for example, received an atomic weight of 0.4.

2) The atomic weight is a ratio quite distinct from the weight in grams.

3) Who knows the atomic weight of the hydrogen atom?

4) Hydrogen is the lightest element with an atomic weight of 1.008.

5) All uranium atoms do not have the same atomic weight.

6) Atomic number 18, atomic weight 39. 948, is a rare gas. 1894 by the British chemist Rayleigh and Ramsay found.

7) Radium, atomic number 88, atomic weight 2260254, is a natural radioelement , elements were derived from Latin, is intended to "ray."

8) This selection of elements also reveals the increase in atomic weight over atomic number.

9) The sum of the masses of protons and neutrons is the atomic weight of the atom.

10) The iron minerals hematite and magnetite have high densities be-cause of the high atomic weight of iron.

11) A hydrogen molecule consists of only two hydrogen atoms with the same atomic weight.

13) A microscale experiment using simple instrument was applied to the determination of Cu atomic weight.

14) Electrons weigh very little, so they aren't even counted in the atomic weight.

15) Science has laid down the principle that the properties of an element are a periodic function of its atomic weight.

16) Atoms of the same element that differ in their atomic weight are called isotopes.
