Formulæ and Equations in Nuclear Chemistry

Nature volume 135, page 185 (02 February 1935) | Download Citation



THE question which Prof. Lowry raises on p. 36 of NATURE of January 5 is one which has perforce exercised my mind in the last few days, since I am at present revising the final page-proofs of the report of the International Conference on Physics. He refers to the different positions in which the numerals indicating the mass and atomic number of a nucleus are placed by different writers. Thus, we have 2He4 and He24. He points out that if the last form is used, there is a difficulty in showing the number of atoms in a molecule in the customary English fashion (for example, C12) whilst both the second and third forms introduce a difficulty for the French chemist, who is in the habit of writing Cl2 for a molecule of chlorine.
