Californium can be used as a neutron source to detect impurities in gold and silver ores. By irradiating them with neutrons, the elements present emit characteristic gamma rays, allowing for their identification and quantification. This process helps ensure the purity and quality of gold and silver products.
Gold can be formed through supernova nucleosynthesis, where the explosion of massive stars creates extreme conditions that allow for the fusion of lighter elements into heavier ones, such as gold. Another way gold can be formed is through neutron capture processes in environments like neutron star mergers, where neutrons bombard existing atomic nuclei, leading to the creation of heavy elements like gold.

Gold has always been present as a mineral in the rocks of earth. Gold was formed in small amounts by nuclear fusion in stars and was "distributed" across space by a super nova however due to its neutron rich construction, most gold was probably originally formed in neutron star explosions or collisions, itself relatively rare. This may explain gold's relative rarity. When earth formed, gold was included in the substance that accreted to make up this planet we're on.
If you add a proton, neutron, and electron to a gold atom, you would obtain a new element called Mercury (symbol: Hg). This new element would have a different number of protons, neutrons, and electrons compared to gold.
The neutron was discovered by Sir James Chadwick in 1932. Chadwick conducted experiments that provided evidence for the existence of a neutral subatomic particle within the atomic nucleus, which he named the neutron.
Assuming the initial speed of the neutron was the same (and assuming they really bounce, which I am not quite sure): less. When bouncing off a hydrogen nucleus, more momentum will be transferred to the hydrogen, because of its lower mass. Most of the momentum will be transferred, in fact, since the masses are more or less equal.
There is no element with the neutron number 30.69. Neutron number is always a whole number as it refers to the total number of neutrons in an atom's nucleus. The closest whole number to 30.69 is 31, so an element with a neutron number of 31 could be gallium (atomic number 31).
A neutron don't contain electrons; the mass of an electron is approx. 1/1850 of the neutronic mass.
There is no such thing as a neutron atom. A neuton is a particle that exists within the nucleus of an atom.
