If I want to figure out how many valence electrons chlorine has, I have to look for the electrons in the outermost shell, or the outermost energy level. How many valence electrons does chlorine have? An atom, which is the fundamental unit of an element, contains an equal number of electrons and protons. Moreover, the electrons used to form bonds with the other atoms is called the valence electrons. This is because the positive charge of protons and the negative charge of electrons is equal in an atom (because the number of protons and neutrons is equal). Answer and Explanation: The group number in which the element belongs to is equal to the total number of valence electrons of that element. 5.05 g 10. Why did clay walker and Lori lampson get divorced? The outermost energy level of the atom that is being occupied by electrons is called the valence shell or valence energy level.
