Br(35) + 2p + 2e == Rb(37)
The atom numbers (between parentheses) by definition are representing the number of protons in the nucleus of that element.
To be neutral, Bromine (atomic symbol Br) has 35 electrons. Ions have more or less.
If an atom has 35 electrons, it will also have 35 protons and its atomic number will be 35. If you go to the periodic table an look up the element with atomic number 35 you will se it is the element Bromine and the symbol for the element is Br.
The Lewis dot symbol of bromine (Br) is represented by the symbol "Br" surrounded by seven dots, with two dots on three sides and one dot on one side. This configuration shows that bromine has seven valence electrons.
Bromine vapor is chemically the same as bromine its just physically different so the symbol is still Br. :-)

the chemical symbol is Br :)
The nuclear symbol of bromine is ^79Br, which represents an atom of bromine with an atomic mass of 79 and an atomic number of 35.
Bromine belongs to 4th horizontal row. Its symbol is Br. It has 7 valence electrons.
Bromine vapor is chemically the same as bromine its just physically different so the symbol is still Br. :-)
The hazard symbol for bromine is YOUR MAM
81Br is one of the stable isotopes of bromine.

The ion bromide is Br-.
To create the Lewis dot structure of bromine (Br), start by placing one dot on each side of the element symbol to represent the valence electrons. Since bromine has 7 valence electrons, place one dot on each side of the symbol, and pair them up as needed. Remember that the octet rule applies - each atom should strive to have 8 electrons in its outer shell.
