Why do electrons start filling the 1st energy level of an atom before the 2nd?
Electrons fill the 1st energy level first because it has the lowest energy and is closest to the nucleus. Electrons are attracted to the positively charged nucleus and fill the energy levels in order of increasing distance from the nucleus.
What is the maximum number of electrons that can fill the second energy?
The second energy level can hold a maximum of 8 electrons. This is based on the formula 2n^2, where n is the principal quantum number representing the energy level.
How many electrons are needed to fill first and second energy level?
The first energy level can hold a maximum of 2 electrons, filling the 1s orbital. The second energy level can hold a maximum of 8 electrons, filling the 2s and 2p orbitals.
What is the total number of electrons needed to completely fill all of the orbitals in an atoms second principal energy level?
The second principal energy level can hold a maximum of 8 electrons in total. This is because the second level consists of one s orbital and three p orbitals, which can hold 2 electrons each.
How many electrons fill the 3rd energy level?
In the 3rd energy level, there can be a maximum of 4 electrons.
How many electrons are needed to fill the second outer energy level?
8 electrons

How many electrons are required to completely fill the third energy level?
no. of electrons to fill an energy level = 2n2. = 2x32 = 18
Does fluroine lose or gain electrons?
Fluorine (F) gains 1 electron to fill its second energy level with 8 electrons.
What is the total number of electrons needed to completely fill all of the orbitals in an atoms second principal energy level?
The second principal energy level can hold a maximum of 8 electrons in total. This is because the second level consists of one s orbital and three p orbitals, which can hold 2 electrons each.
Why is the 11th electron of the sodium atom located in the third energy level?
Each energy level can hold different number of electrons. The first energy level holds 2, second holds 8, and third holds 8. Because the first two energy levels of sodium can only hold 10 electrons, the sodium has a third energy level to hold the 11th electron.
How many electrons fill the 3rd energy level?
In the 3rd energy level, there can be a maximum of 4 electrons.
How many electron are needed to fill the outer energy level of sulfur?
Sulfur has 6 electrons in its outer energy level. This means it needs 2 more electrons to fill its outer energy level, for a total of 8 electrons.
How can atoms with fewer than 8 valence electrons fill their outmost energy level?
They ca fill their outmost energy level by gaining or losing electrons.
What two atoms will have their outer energy level filled with two electrons?
Helium and neon will have their outer energy level filled with two electrons. Helium has 2 electrons in its only energy level, while neon has 8 electrons in its second energy level.
