WebElectrons that are not in the valence level are not shown in the Lewis symbol. The reason for this is that the chemical reactivity of an atom of the element is solely determined by the number of its valence electrons, and not its inner electrons.Lewis symbols for atoms are combined to write Lewis structures for compounds or molecules with bonds between atoms. WebThe halogens, alkali metals, and alkaline earth metals have _____ valence electrons, respectively. A) 7, 4, and 6 B) 1, 5, and 7 C) 8, 2, and 3 D) 7, 1, and 2 E) 2, 7, and 4 9. ...

WebHow many electrons does bromine (Br) have? How many electrons does the bromine of BrF_3 have in its outermost valence shell? Explain. How many pairs of valence electrons do the bromine atoms have in the following molecules and ions. 1. BrF 2. B r F + 2 3. B r F + 6 4. B r F 2 5. B r F 5; How many half filled orbitals are there in a bromine atom? WebValence electrons are responsible for the reactivity of an element. They determine how "willing" the elements are to bond with each other to form new compounds. If the valence shell of an element is full, such as with a noble gas, then the element does not want to gain or lose an electron. For example, alkali metals, which all have a valency of ...
