Question
An atom of carbon (C) has an electron configuration of 2.4. Identify how many valence electrons that it has.
Solution
An atom of carbon has 4 valence electrons. This is determined by looking at the electron configuration of the atom. The electron configuration of carbon is 2.4, which means there are 2 electrons in the first energy level and 4 electrons in the second energy level. The electrons in the outermost energy level, also known as the valence shell, are the valence electrons. Therefore, carbon has 4 valence electrons.
