Carbon has more valence electrons than hydrogen. Carbon, located in Group 14 (or Group IVA) of the periodic table, has four valence electrons. It belongs to a group of elements called the "tetrels," and its electronic configuration is 1s² 2s² 2p², indicating that it has two electrons in the 2s orbital and two electrons in the 2p orbital.
On the other hand, hydrogen, which is located in Group 1 (or Group IA), has only one valence electron. It has a single electron in its 1s orbital, denoted by the electronic configuration 1s¹.
So, carbon has four valence electrons, while hydrogen has one valence electron.
