WebAboutTranscript. Valence electrons are the electrons in the outermost shell, or energy level, of an atom. For example, oxygen has six valence electrons, two in the 2s subshell and four in the 2p subshell. We can write the configuration of oxygen's valence electrons as 2s²2p⁴. Created by Sal Khan. WebHere are the number of valence electrons in each of the elements you've mentioned: Part A: Ba (Barium) - Ba is in Group 2 of the periodic table, so it has 2 valence electrons. Part B: Ca (Calcium) - Ca is also in Group 2 of the periodic table, so it also has 2 valence electrons.
WebIn chemistry, valence electrons are often the focus of study because they play a vital role in the bonding behavior of an atom. Dr. Nivaldo Tro defines valence electrons as those that exist in the outermost energy shell of an atom. Quickly identifying the number of valence electrons is important in mastering ... Web3 apr. 2013 · Valency is a concept that describes the power of an element to bind to other elements.
