The newly discovered element - 117 (named tennessine) for the Oak Ridge Laboratory where experiments took place) is made by bombarding an atom of berkelium - 249 with an atom of calcium - 48 to produce tennessine - 294 . Neutrons are also produced in this reaction. How many neutrons must be produced for the nuclear equation to be balanced ? 48 20Ca+ 249 97Bk>294 117Ts+

1 answer

Nuclear equations must be balanced in terms of both atomic mass and atomic number. To balance the equation, you need to ensure that the total number of protons and neutrons on both sides of the equation are equal.

On the left side of the equation:
- 48 is the atomic number of calcium (protons) and has an atomic mass of 48.
- 249 is the atomic number of berkelium (protons) and has an atomic mass of 249.

So, on the left side, you have a total of 48 protons and 249 protons in calcium and berkelium, respectively.

On the right side of the equation:
- 294 is the atomic number of tennessine (protons) and has an atomic mass of 294.

To find the number of neutrons produced, subtract the sum of protons on the right side (294) from the sum of protons on the left side (48 + 249):

294 - (48 + 249) = -3

Since you cannot have a negative number of neutrons, this means that the equation is not balanced.
