WebAn atom consists of 3 main parts: " blank " , " blank ", and " blank " . protons, neutrons , electrons Protons and neutrons are in the " blank " ( the center of the atom ), while electrons " blank " the nucleus. nucleus, orbit Protons have a " blank " (+), neutrons are " blank " (0), while electrons have a " blank " (-). WebReal photons are measured in two varieties of electromagnetic calorimeter (see Fig. 3 ). Because virtual photons of mass M decay in times of order ℏ/ M to “di-lepton pairs” consisting of e+e− or μ + μ −, they are detected in PHENIX via charged particle spectrometers which specialize in electron or muon measurements.

Web16 hours ago · The mass number (represented by the letter A) is defined as the total number of protons and neutrons in an atom. Consider the table below, which shows data from the first six elements of the periodic table. Consider the element helium. Its atomic number is 2, so it has two protons in its nucleus. Its nucleus also contains two neutrons.
