Medication Summary. Topical antibiotics, systemic antibiotics, or a combination of both is effective therapy for impetigo. Empiric bacterial coverage is aimed at eradicating Staphylococcus aureus and group A beta-hemolytic streptococci (GABHS; also known as Streptococcus pyogenes).
In chemistry, the valence or valency of an element is a measure of its combining power with other atoms when it forms chemical compounds or molecules. The concept of valence was developed in the second half of the 19th century and was successful in explaining the molecular structure of inorganic and organic compounds.
Re: Valence electron question. Permalink Submitted by kingchemist on Thu, 2009-10-08 15:38. Valence electrons are the outermost electrons in an atom/ion. The atom Ne has an electron arrangement of 2,8 so this has 8 valency electrons. This is a stable arrangement and atoms like Ne do not join to other elements. Is the example Ne 2+? If it is, it will have the arrangement 2,6 so would have 6 valence electrons
