How many electrons are needed to fill the second outer energy level?
8 electrons
How many electron are needed to fill the outer energy level of sulfur?
6 electrons
What two atoms will have their outer energy level filled with two electrons?
Hydrogen and Helium both only need two valence electrons to fill their outer shell.
How many electrons does Sodium need to fill it's outer energy level?
It needs to lose one electron so that it can have 8 electrons in its outer orbital
How many valence electrons in fluorine are needed to have a filled outer energy level?
it has 2 because the first energy level has 1
What is the number of electrons to fill fluorine?
it has 7 valence electrons, which is the number of electrons on the outer energy level, so it needs 7.
How many electrons are required to completely fill the third energy level?
no. of electrons to fill an energy level = 2n2. = 2x32 = 18
How many electrons fill the 3rd energy level?
In the 3rd energy level, there can be a maximum of 4 electrons.
How many electrons does it take to fill outer shell of nitrogen?
Nitrogen has two energy levels. The first energy level contains two electrons. The second energy level contains five electrons. Number of Protons/Electrons: 7 Number of Neutrons: 7
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.
How can an atom that has seven valence electrons complete its outermost level?
Look at the first element on the periodic table. The first energy level holds only two electrons, so Helium has filled its outer energy level. Atoms with an outer energy level that is not fill will fill it up by bonding with other atoms and sharing electrons.
How many electrons does hydrogen have to fill its outer shell?
Hydrogen has one electron. Its outer shell the first energy level has just one orbital, 1s which could hold a maximum of 2 electrons, so hydrogen only partially fills the level.
