Publisher: Khan Academy This free online course on elements, atoms and the periodic table will give you comprehensive knowledge of the two fundamental aspects of chemistry which are first, the structure of the atom and the role of the subatomic particles neutrons, protons and electrons, and second, the atomic structure of elements. Since there's no high school chemistry course on KA yet, I'm trying to figure out how best to use Khan Academy to get up to speed on chem so I have the foundations to do the AP/College Chemistry course. Isso acontece pelo aumento da carga nuclear, que resulta no elétron mais externo ser ligado mais fortemente ao núcleo. Practice Questions. Elements in the same group have the same number of valence electrons and typically tend to form similarly charged ions.
