WebAug 18, 2024 · Electrons are organized into shells and subshells around nuclei. The first shell can fit a maximum of two and the second shell can fit a maximum of eight electrons. Valence electrons are in the highest-numbered (outer) shell; all other electrons are core electrons. Key Takeaway

WebElements from the fourth column of the periodic table, like carbon, have four electrons in their outermost electron shell or four valence electrons. Fluorine is in the seventh column … WebSo 2p2. So how many valence electrons does it have? Well, in its second shell, its outermost shell, it has two plus two, it has four valence electrons, and that's going to be true for the things in this group, and because of that, carbon has similar bonding behavior to silicon, to the other things in its group. earth n wood cuyahoga falls
