The total atomic number must be the same on each side. The total mass number must be the same on both side.
<span>On the RHS, for the mass number, we have 257 + 4 = 261 (the 4 comes from the 4 neutrons). That means the mass number of the missing piece on the LHS is 261 - 247 = 14. </span>
<span>One the RHS, for the atomic number we have a total of 104 since the 4 neutrons are all neutral. On the LHS, we have this: 104 - 98 = 6. </span>
<span>The missing piece is a nucleus of carbon 14. Done in your style, it is 14/6C</span>
Answer:
A. Chemical name
Explanation:
The Chemical Name is the name generated by applying the naming conventions of the International Union of Pure and Applied Chemistry (IUPAC). The correct names of compounds contained in drug products can be formed by implementing these rules
