In which process does an atom split into two smaller atoms? a. beta decay b. gamma decay c. nuclear fission d. nuclear fusion

If a uranium atom absorbs a neutron it will be unstable, and will generally split into two fragments. This process, the splitting of a large nucleus into two smaller ones, is known as NUCLEAR FISSION.

Hope this helps

Your answer would be C. nuclear fission

Explanation:

This is the answer because, nuclear fission happens when the nucleus of an atom is split into two pieces. This releases alot of heat. In other words a nuclear reactor, a chain reaction occurs. Meaning when one atom is split it causes other atoms to split as well.

the density of gold = 19.3 g/cm3

the relation between density and mass and volume is

density = mass / volume

given :

mass of gold = 13 g

density = 13g / volume = 19.3

volume = 13 /19.3 = 0.67 cm^3

thus volume of gold nugget = 0.67 cm^3
