Balance this nuclear reaction by supplying the missing nucleus.? 249/98cf + > 257/104rf + 4 1/0n

The missing nucleus is carbon-12:

Explanation:

The nuclear reaction given is:

+ ___ →

To balance this equation you must add a nucleus which contains the missing mass and atomic numbers.

Mass number is the number of protons plus neutrons and is the superscript to the left of the chemical symbol: 249 for Cf, 257 for Rf, and 1 for n (neutron).

Atomic number is the number of protons and is the subscript to the left of the chemical symbol: 98 for Cf, 104 for RF and 0 for n.

Thus, the balance is:

Mass number:

Atomic number:

Then, you are looking for a nucleus (or gropu of nuclei) which supply 6 protons and 6 neutrons. That is a nucleus of carbon-12: .

The balanced nuclear reaction is:
