How does the trigger system select interesting events? What is data acquisition in particle physics experiments?

Sep 14, 2016 ... The identity of the element is determined by the number of protons, which are positively charged, massive nuclear particles. The number of ... The three main subatomic particles that form an atom are protons, neutrons, and electrons. The center of the atom is called the nucleus. For example, a carbon atom has six protons, but an atom with only five protons is boron while an atom with seven protons is the element nitrogen. Neutrons are ... Atomic History and Subatomic Particles. Explore the history and development of the atomic model and characteristics of subatomic particles (protons, neutrons, ... If you change the number of electrons you create ions. A loss of electrons is going to lead to an anion. A gain of electrons is going to lead to a cation. Subatomic particles in atoms · number of protons = atomic number · number of neutrons = (mass number) – (atomic number) · number of electrons = number of protons ... The two subatomic particles are the protons and neutrons. The atomic mass is essentially equal in magnitude to the protons and neutrons as the mass of an ... Subatomic particles are extremely small pieces of matter. These particles are smaller than, and generally parts of, atoms, the fundamental components of all ... Hydrogen contains only a single proton and no neutrons. The number of protons in an atom determines its atomic number in the Periodic Table of Elements. The ... All matter, with the exception of sub-atomic particles, is made up of atoms that contain an outer shell of electrons and an inner nuclear core.
