How many neutrons does bromine-79 have?
44 neutrons
Bromine has an atomic number of 35, and so has 35 protons. You are told that the mass number is 79, and so there are a total of 79 protons plus neutrons. Therefore there must be (79 – 35) neutrons = 44 neutrons.
How many protons electrons and neutrons are in bromine?
Bromine has a mass number of 80 and 35 protons so 80-35 = 45 neutrons. b) How many electrons does the neutral atom of bromine have? The neutral atom of bromine has 35 electrons because the number of electrons equals the number of protons.
How many atoms does bromine-79 have?
Bromine-79 atom is the stable isotope of bromine with relative atomic mass 78.918338, 50.69 atom percent natural abundance and nuclear spin 3/2. A halogen with the atomic symbol Br, atomic number 35, and atomic weight 79.904.
How many protons neutrons and electrons are in selenium 79?
Selenium-79 is composed of 34 protons, 45 neutrons, and 34 electrons.
What is the name of the element with 79 protons?
element gold
The element gold. Gold is element 79 and its symbol is Au.
What is the difference between bromine 79 and bromine 81?
The atomic mass of bromine (Br) is 79.90. There are two main isotopes at 79 and 81, which average out to the 79.90amu value. The 79 has 44 neutrons and the 81 has 46 neutrons. While it won’t change the average atomic mass, scientists have made bromine isotopes with masses from 68 to 97.

What is the mass of BR − 79?
79.904 amu
3. Bromine has two naturally occurring isotopes (Br-79 and Br-81) and an atomic mass of 79.904 amu.
Which element has a mass number of 79?
Gold
Gold is element 79 and its symbol is Au.
What isotope has 79 protons 120 neutrons?
Along with the four protons, the collision-induced reactions had removed anywhere from six to 15 neutrons, producing a range of gold isotopes from gold 190 (79 protons and 111 neutrons) to gold 199 (79 protons, 120 neutrons), the researchers reported in the March 1981 issue of Physical Review C.
What element has 79 neutrons?
Gold is element 79 and its symbol is Au.
What isotope has 79 electrons?
Outside the nucleus of the gold atom are 79 electrons (negative charges).
How many protons neutrons and electrons does bromine 81 have?
How does an atom of bromine 79 become a bromide ion with a 1 charge?
Correct answer: In order to become a bromide ion, the bromine atom must gain one electron. This gives it a charge of negative one, but allows it to satisfy the octet rule, making it a very stable ion. With the ionization, the atom now has 36 electrons.
