How many electrons are in the outer shell of the atom of the elements in the second and third rows of the periodic table?
The second and third energy levels of an atom each contain 8 electrons. That is why there are eight elements on the second row (Lithium, Beryllium, Boron, Carbon, Nitrogen, Oxygen, Fluorine, and Neon) and third row (Sodium, Magnesium, Aluminum, Silicon, Potassium, Sulfur, Chlorine, and Argon) of the Periodic Table.
What else can I help you with?
How many electrons will the elements have in the second group have on the periodic table?
Elements in the second group of the periodic table, also known as Group 2 or the alkaline earth metals, will have 2 electrons in their outer shell. This gives them a full s subshell and makes them relatively reactive.
Using the periodic table predict how many outer level electrons will be in elements 114 116 and 118?
Elements 114, 116, and 118 are in period 7 of the periodic table, so they will have 7 outer level electrons. Each period in the periodic table represents the number of electron shells an atom has, and the elements in the same period will have the same number of outer level electrons.

What are the different elements that contain the same number of outer electrons as sodium?
Elements in the same group as sodium on the periodic table, such as lithium and potassium, also contain the same number of outer electrons (1) as sodium. These elements belong to Group 1 or the alkali metals group, and they share similar chemical properties due to their outer electron configuration.
What is a family on the periodic table?
A family is a column in a periodic table; all elements in a family have similar physical and chemical properties, because they have the same numbers of valence electrons (outer electrons).
