If two of those nucleons are protons, the other two must be neutrons. The most important isotope - polonium 210 - has 84 protons and 126 neutrons. Polonium has an atomic number of 84 how many protons and electrons does have? Polonium has 84 protons and electrons. Thus polonium-210 (mass number 210 and atomic number 84, i.e., a nucleus with 84 protons) decays by alpha emission to lead-206 (atomic number 82). Polonium is now usually obtained by irradiating bismuth with high-energy neutrons or protons. [14] [52] In 1934, an experiment showed that when natural 209 Bi is bombarded with neutrons , 210 Bi is created, which then decays to 210 Po via beta-minus decay.

All these three subatomic particles construct an atom. A neutral atom have equal number of proton and electron.

It has 126 neutrons and 84 protons, a ratio of 1.5 to 1. It omits an alpha particle to leave 124 neutrons to 82 neutrons and thus the ratio becomes 1.51 to 1. Mass numbers of typical isotopes of Polonium are 208-210. The total number of neutrons in the nucleus of an atom is called the neutron number of the atom and is given the symbol N. Neutron number plus atomic number equals atomic mass number: N+Z=A. Polonium. Illustration about composition, electrons, symbol, structure, neutrons, atoms, polonium, science, isolated, rendering, formula, background, chemistry Se hela listan på fr.wikipedia.org I think the correct answer would be A. When a polonium atom with 84 protons, 124 neutrons, and 84 electrons undergoes alpha decay, a lead atom would be produced with 82 protons, 122 neutrons, and 84 electrons together with an alpha particle having two protons and two neutrons.

2009-10-27 How many protons electrons and neutrons does polonium-210 have? - Answers.

The most important isotope - polonium 210 - has 84 protons and 126 neutrons. Polonium has an atomic number of 84 how many protons and electrons does have? Polonium has 84 protons and electrons. Thus polonium-210 (mass number 210 and atomic number 84, i.e., a nucleus with 84 protons) decays by alpha emission to lead-206 (atomic number 82).
