Proton number, neutron number and electron number in 81 Br-1? Best Answer: All Br atoms have 35 protons (the atomic number of Br). Since 81 is the mass number (sum of protons + neutrons), this atom has 81-35 = 46 neutrons. An uncharged atom of bromine will have the same number of electrons as protons. Since this atom has a -1 charge, it has one additional electron. So, it has 36 electrons.

How many protons, neutrons and electrons does sulfur have? Atomic number (number of protons) = 16. Atomic mass (~number of protons and neutrons) = 32. Therefore: Number of neutrons = 32 - 16 = 16. For a neutral atom, the number of electrons simply equals the number of protons. All isotopes of sulfur will therefore have 16 electrons.

How many protons, neutrons, and electrons are in a neutral atom of sodium? The Mass Number of an element is equal to the protons added to the neutrons. The element Sodium has an atomic number of 11 and an average atomic mass of 22.98 which makes the mass number 23. Therefore. An atomic number of 11 means this atom will have 11 protons. A mass number of 23 means 23 - 11 this atom will have 12 neutrons. Since this atom is neutral the positive protons must be equal to the negative electrons. This atom will have 11 electrons.

Nuclear magnetic resonance The number on the lower left of the symbol is the atomic number (or the number of protons). You will also notice that all of these have the same atomic number because they are all carbon atoms. The top number equals the number of protons plus the number of neutrons. This is called the mass number. So on the first one, the mass number is 12 indicating that the total number of protons and neutrons is 12.

Uranium Enrichment These are the different uranium isotopes. Isotopes of uranium contain 92 protons in the atom's center or nucleus. (The number of protons in the nucleus is what makes the atoms uranium.) The U238 atoms contain 146 neutrons, the U235 atoms contain 143 neutrons, and the U234 atoms contain only 142 neutrons. The total number of protons plus neutrons gives the atomic mass of each isotope — that is 238, 235, or 234, respectively.
