What Are Valence Electrons? - Lesson for Kids - Study.com

WebElectrons in the outermost shell (valence electrons) are more shielded and farther from the nucleus on average, so they have the lowest binding energies of all of the electrons in an atom. In contrast, electrons in inner shells (core electrons) are less shielded and closer to the nucleus on average, so they have higher binding energies. WebVariation Of Oxidation State Along a Period. While moving left to right across a period, the number of valence electrons of elements increases and varies between 1 to 8. But the valency of elements, when combined with H or O first, increases from 1 to 4 and then it reduces to zero. Consider two compounds containing oxygen Na 2 O and F 2 O.
