28^Si and 14 protons
The metalloid Si (silicon) is correctly matched with 14 protons, because the atomic number of Si is 14.

Here is the isotopic notation for carbon 14. From looking at the isotopic notation, you can find the number of protons, neutrons and electrons in an atom. Protons- The atomic number is 6, so there are 6 protons Electrons- If the atom is neutral the number of protons equals the number of electrons, so there are also 6 electrons Neutrons- The mass number equals the number of protons + neutrons, and 14-6 leaves 8 neutrons 14 C 6
Each chemical symbol is for a chemical element; each chemical element has a specific atomic number and an atomic weight (not mass, after the rule of IUPAC).

Lee Harvey Oswald was shot by Jack Ruby before the trial could be held. jack Ruby died in prison due to cancer.
Easier than using the Bohr model. The pair of dots between the symbols identifies a covalent bond.
