WebValence 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. Sort by: Top Voted Questions Tips & Thanks Cyan 2 years ago WebCarbon has an atomic number of six (meaning six protons, and six electrons as well in a neutral atom), so the first two electrons fill the inner shell and the remaining four are left in the second shell, which is the valence (outermost) shell.

Valence electrons (video) Khan Academy

WebElectrons generally go into the orbital with the "lowest energy." The first orbital that fills up is called the 1S orbital. This one can hold 2 electrons. Once you get to the third electron, you have to put it in the next orbital. This one is called the 2S orbital. (All "S" orbitals hold 2 electrons.) Next comes the 2P shell. WebValence electrons are the electrons present in the outermost shell of an atom. You can easily determine the number of valence electrons an atom can have by looking at its Group in the periodic table. For example, atoms in Groups 1 and 2 have 1 and 2 valence electrons, respectively. Atoms in Groups 13 and 18 have 3 and 8 valence electrons ... dictionary curate
