Answer:
Uranium-235 absorbing a neutron and breaking into Barium-141, Krypton-92 and three neutrons
Explanation:
A fission reaction is said to have occurred when an unstable nucleus is bombarded with a neutron such that it disintegrates into daughter nuclei and produces more neutrons in the process. Hence, Uranium-235 absorbing a neutron and breaking into Barium-141, Krypton-92 and three neutrons is a fission reaction.
This fission reaction is often a self sustaining reaction. The neutrons produced in the reaction bombards more of the parent nucleus and the process continues indefinitely(chain reaction).
Control rods and moderators are used to keep the chain reaction in check.

Lipids serve as structural components of cell membranes, function as energy storehouses, and function as important signalling molecules. They include fats, waxes, oils, hormones, and certain components of membranes and function as energy-storage molecules and chemical messengers.
Hope this helped :)
Answer:
A positive ion has more protons than electrons and a negative ion has more electron ions
So the answer is
A positive ion has less electrons and a negative ion has more electrons
