What is the nucleus of bromine?
The nucleus consists of 35 protons (red) and 44 neutrons (blue). 35 electrons (green) bind to the nucleus, successively occupying available electron shells (rings). The stability of an element’s outer electrons determines its chemical and physical properties.
What is atomic structure of bromine?
Bromine is an element, found in Group 17 (halogens) of the periodic table. Its atomic symbol is Br, atomic number is 35, and atomic weight is 79.9. Its atomic structure includes a nucleus with 35 protons and 45 neutrons, and four electron shells with a total of 35 electrons.
How big is a bromine ion?
The bromide ion has an ionic radius of 196 pm.
Which has larger size Br or Br?
Answer and Explanation: The bromide ion Br- has the larger radius.

How many neutrons are in the nucleus of an atom of bromine 79?
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.
Which has the largest atomic size?
Francium has the largest atomic size on the periodic table, and helium has the smallest atomic size.
How do you compare atomic size?
The size of an atom can be estimated by measuring the distance between adjacent atoms in a covalent compound. The covalent radius of a chlorine atom, for example, is half the distance between the nuclei of the atoms in a Cl2 molecule. The covalent radii of the main group elements are given in the figure below.
Which one has greater atomic size?
Atomic radii vary in a predictable way across the periodic table. As can be seen in the figures below, the atomic radius increases from top to bottom in a group, and decreases from left to right across a period. Thus, helium is the smallest element, and francium is the largest.
Which element has smallest nucleus?
Helium
The correct answer is Helium. Its atomic number is 2 and its mass number is 4. It was discovered by Lockyer and Janssen.
What is present in the nucleus of 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.
