In the mid 1930s enrico fermi bombarded uranium with thermal neutrons and observed the release of a large amount of energy. this happened because the heavy uranium nucleus split into two lighter nuclei, releasing two or three neutrons along with a large amount of energy. what is this process called?

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.

the earth would become to overheated and everything alive on it will eventually die from overheating. plants will eventually die as well, water will evaporate, and it will be nothing but a hot planet without anything living on it.
