Which alkaline earth metal has 3 occupied energy levels?
The alkaline metal with three rings would be magnesium(Mg). It has an atomic number of 12 and atomic mass if rounded is 24. Protons and eletrons are 12 (Electrons are always the same number as protons and the number of protons is the same as the atomic number)and Neutrons( found out by subtracting the atomic mass from the number of protons) is 12. It would have 3 rings because there are 12 electrons. So, 2 electrons can be in the first orbit, 8 in the second, and 8 in the third. Basically you must fill up the first and second orbit and then in the third you have only 2.
What planet do the thundercats come from?
The Thundercats hail from the planet of Thundera (spelled ThunDERa in all of the officially released Thundercarts books of the period). The planet was destroyed, hence why the inhabitants had to make a mass exodus.

Is potassium and magnesium in the same period?
Potassium and magnesium are not in the same period on the periodic table. Potassium is in the fourth period (row) while magnesium is in the third period. They are both in the same group (column), Group 2, which are known as the alkaline earth metals.
What is the least electronegative element in the third period?
It is sodium metal.

Group 2 Period 3
What alkali earth metal has electrons in exactly three energy levels?
Calcium is the alkaline earth metal that has electrons in exactly three energy levels. Its electron configuration is [Ar] 4s2, and it has two electrons in the 4s orbital and a total of three energy levels.
What is a valence shell of mg?
The valence shell of magnesium (Mg) contains 2 electrons in the outermost energy level. This is because magnesium is an alkaline earth metal with 2 valence electrons. These electrons are located in the 3s orbital in the third energy level.

What is the non metal in the third period with six outer electrons?
Oxygen is the only nonmetal with 6 Valence Electrons in period 2.
Third most abundant metal on earth?
The third most abundant metal on Earth is aluminum. It is found in various minerals and ores, and is widely used in industries such as construction, transportation, and packaging due to its lightweight and corrosion-resistant properties.
