Valence Electrons Every atom that exists has a specific number of valence electrons. If it is a main group element (groups IA - VIIIA), the group number tells us how many valence electrons it has. We represent these electrons as dots surrounding the element's symbol. Answer and Explanation: The electron dot structure for atomic bromine is:
For Bromine atom: a) Determine the total number of unpaired electrons. b) Write the electron configuration. c) Identify the core electrons and the valence electrons.
The 7 electrons in its outermost shell, called valence electrons, are why this element is classified as a halogen. This electron configuration of a bromine atom can be written as:
A bromine (Br) atom has 7 valence electrons. Valence electrons are the outermost electrons in an atom, which affect how atoms might react with one... See full answer below.
Valence Electrons Valence electrons are the electrons in an atom located at the highest energy level. Valence electrons are the electrons that determine chemical reactivity, so elements with the same number of valence electrons have similar chemical reactivity.

Valence electrons are the electrons in the outermost shell of an atom and they are the electrons available for forming chemical bonds with other atoms.
For Bromine atom: a) Determine the total number of unpaired electrons ...
A group of elements all have the same number of valence electrons, or the same number of electrons in their outermost electron shell.
