Find an answer to your question “How many total protons neutrons and electrons are in an atom of iodine with a mass number of 127 ...” in Chemistry if the answers seem to be not correct or there’s no answer. Bromine (Br), at atomic number 35, has a greater variety of isotopes. If you're not told the element name or its atomic number, it's hard to know the correct answer. Answer to What is the net charge of an iodine ion containing 53 protons, 74 neutrons, and 54 electrons?. But iodine, like all basic elements, comes in different "isotopes," or versions of the element. There are 53 electrons as this iodine is electrically neutral so the number of protons equals the number of electrons. The atomic number of iodine (53) tells us that a neutral iodine atom contains 53 protons in its nucleus and 53 electrons outside its nucleus. Atomic Number.

The atomic symbol is written with the atomic number on the lower left and the mass number on the upper left, so it is 12953I. true or false: The Ti2+ ion … It has a radioactive decay half-life of about eight days. Atomic no. Because these particles have the same but opposite charges, equal numbers cancel out, producing a neutral atom. There are two main isotopes at 79 and 81, which average out to the 79.90amu value. The excess neutrons act somewhat like nuclear glue. by erica.thomas. Finish Editing. 0. The mass number is different for each different isotope of a chemical element. Not enough, can cause body problems Anything above 0.15% weight in human body is an important element Anything below 0.05 is a trace element 6protons X 2 = 12 mass number Hydrogen’s protons play major role in mass number but neutrons are negligible (atomic number and mass number are 1) Protons and neutrons in … To play this quiz, please finish editing it. … The neutral atom of bromine has 35 electrons because the number of electrons equals the number of protons.

Protons. Likewise, people ask, how many protons neutrons and electrons are present in a single atom of bromine − 81? THINK BIG. We have not had protons. Because the sum of the numbers of protons and neutrons equals the mass number, 127, the number of neutrons is 74 (127 − 53 = 74). That 16 is the atomic number, so 16 protons. How many protons, neutrons, and electrons are in a specific kind of atom? Save. Once again, atomic number is the number of protons 43. Is it beryllium with 4 protons and 1 neutron? Protons, neutrons and electrons of all elements are mentioned in the table below. The atomic number of iodine (53) tells us that a neutral iodine atom contains 53 protons in its nucleus and 53 electrons outside its nucleus. Thus, neutral iodine would have 53 protons and 53 electrons.
