WebbProtons and Neutrons in Potassium. Potassium is a chemical element with atomic number 19 which means there are 19 protons in its nucleus. Total number of protons in the nucleus is called the atomic number of the atom and is given the symbol Z.The total electrical charge of the nucleus is therefore +Ze, where e (elementary charge) equals to 1,602 x 10 … WebbNuclear reactions that occur in a time comparable to the time of transit of an incident particle across the nucleus (~10-22 s) are called direct nuclear reactions. Interaction time is critical for defining the reaction mechanism. The very short interaction time allows for an interaction of a single nucleon only (in extreme cases). locked roses
