To hopefully clarify further, Say I followed the same steps for an atom of chlorine. 9 years ago. 4 years ago. You can sign in to vote the answer. Lv 4. Isotopes of Bromine For bromine, the atomic number is 35. If an element has isotopes which are radioactive in nature, then they are called radioisotopes. For a neutral atom of Bromine: Protons: 35 . What is the structure of this atom? But how can I say an atom of bromine contains 45 neutrons, when its two stable isotopes contain either 44 (bromine 79) or 46 (bromine 81)?. Number of neutrons is the mass number minus the atomic number. Solution for Determine the number of neutrons in a bromine nucleus, which has a radius of approximately 5.36 10−15 m. … Sign in *Move with Wisdom* Lv 4. Tin is the element which has maximum number of stable isotopes which is 10. Solution for A bromine atom has an atomic number of 35 and an atomic mass of 80. So, Nucleons = (Number of Protons) + (Number of neutrons). (a) atomic number 26, mass number 58, charge of 2+ (b) atomic number 53, mass number 127, charge of 1− (a) Iron, 26 protons, 24 electrons, and 32 neutrons; (b) iodine, 53 protons, 54 electrons, and 74 neutrons. Determine the number of protons, neutrons and electrons in each and name them. BROMINE Atomic Number 35 Number of Neutrons 45 Atomic Mass 79.904 Symbol Br Melting Point −7.2°C, 19°F, 266 K Boiling Point 58.8°C, 137.8°F, 332 K Density (g cm−3) 3.1028 Discovery Date 1826 Discovered By Antoine J. Ballard Isotopes Two naturally existing isotopes of bromine exist, bromine-79 and bromine-81. 0 0? That would be 80-35, giving me 45 neutrons. Electrons: 35. The atomic number is equal to the number of protons and electrons. 0 0. Source(s): Neutrons: (79.905-35) = 44.905 --> Round up: 45. O A. How do you think about the answers? Atomic Number Of Bromine. Number Of Neutrons In Bromine. Source(s): It has a central nucleus composed of… 79 Br and 81 Br are the two stable isotopes of bromine.
