Describe how you would draw the electron dot structure for bromine and then draw the structure.

Electron dot structures are the structures which represent the valence electrons of the element around the chemical symbol of the element.

Bromine is an element which belong to group 17 and is a halogen. Atomic number of bromine is 35 that means it contains 35 electrons, Thus the electronic configuration is represented as:

Thus the valence electrons are 7. Thus 7 electrons are represented around chemical symbol of Bromine i.e. Br.

"among the transition metal elements, manganese and zinc have a slight lowering of electronegativities. the reason behind this is that the nuclear charges of these elements are slightly weaker than the other transition metal elements due to the way their valence electrons are filled up. both manganese and zinc have their valence electrons filled up to the 4th shell with 1 pair of electrons (4s2) completely occupying it. although the electrons in the 3rd shell (3d) are yet to be paired since the outer most shell is filled up, the ability of the nucleus to attract electrons is lessened. hence,   the electronegativity (or the ability to attract electrons) is lessened."
