## How many protons neutrons and electrons does bromine-79?

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….Protons, neutrons and electrons.

relative mass relative charge
electron 1/1836 -1

What is the atomic number of bromine 80?

The atomic # is 35, it means the atomic number of a chemical element (also known as its proton number) is the number of protons found in the nucleus of an atom of that element, and therefore identical to the charge number of the nucleus.

What element has an atomic mass of 79?

element gold
The element gold. Gold is element 79 and its symbol is Au.

### How many neutrons are in bromine 79?

How many neutrons does bromine 80 have?

45 neutrons
a) How many neutrons does the atom of bromine have? The mass number = protons + neutrons. Bromine has a mass number of 80 and 35 protons so 80-35 = 45 neutrons.

What isotope has 15 protons 15 electrons and 17 neutrons?

What element has 15 protons and 17 neutrons and 15 electrons? Phosphorus-32 (32P) is a radioactive isotope of phosphorus.

## What does the number 80 in bromine 80 represent?

The mass number of bromine is 80. This value is the sum of the number of protons and the number of neutrons.

How many protons neutrons and electrons does bromine 80 have?

35 protons
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.

What isotope has a mass number of 197 and 79 electrons?

gold
According to the list of elements given inside the front cover, gold has an atomic number of 79. Consequently, an atom of 197Au has 79 protons, 79 electrons, and 197 – 79 = 118 neutrons. (b) The atomic number of strontium (listed inside the front cover) is 38.

### What is the use of BR-79?

Both Bromine Isotopes are used in nuclear medicine. Br-81 is used for the production of the radioisotope Kr-81m which is used for diagnostics. Br-79 can be used for the cyclotron production of Kr-77 which decays to the radioisotope Br-77 although the most common production route for Br-77 is via Se-77.

What is the isotope of bromine with the atomic number 79?
