How to Find the Valence Electrons for Calcium (Ca) - YouTube

Web20 feb. 2024 · So, for our example, we would say that sodium has 2 electrons in the 1s orbital plus 2 electrons in the 2s orbital plus 6 electrons in the 2p orbital plus 1 electron in … WebIt has eight valence electrons. One, two, three, four, five, six, seven, eight in that fifth shell. Xenon is a member of the zero-valence elements that are called noble or inert gases. It is inert to most common chemical reactions (such as combustion, for example) because the outer valence shell contains eight electrons. caneinght
