Question #67212

Answer 1

Maybe that means that two or more atoms are joined to form a stable molecule and the total number of protons in those atoms is 14.

You can try by combining the first 13 atoms, H (one proton), Li (three protons), Be (four protons); B (five protons); C (six protons ); N (seven protons); O (eight protons), F (nine protons), Na (eleven protons), Mg (twelve protons), Al (thirteen protons). Helium and Neon atoms can't be considered,

I have found stable molecules of `CO, C_2H_2, N_2, HCN`.

Answer 2

Other options could be: b) number of different protons (hydrogen atoms) bonded with different chemical shift in NMR; c) numer of hydrogen atoms (e.g. `C_6H_14`); d) number of ionizable hydrogen atoms per molecule.
