2n^2 = 18 therefore n^2 = 9 therefore n = 3
In the 3rd energy level, there can be a maximum of 4 electrons.
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.
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.
1s = 2 + 2s & p = 8 + 3s & p & d = 18 + 4s & p & d & f = 32 { close to binary } + = Total is 60 electrons.
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.
no. of electrons to fill an energy level = 2n2. = 2x32 = 18
The third energy level can hold a maximum of 18 electrons.
No, you are misinformed, it is electrons not gasses that fill energy levels.
In the 3rd energy level, there can be a maximum of 4 electrons.
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.
They ca fill their outmost energy level by gaining or losing electrons.
18
Carbon has four electrons in the outermost energy level, which is energy level two. It needs eight electrons to have this energy level filled.
The first energy level can take a maximum of two electrons.
obviously
8 electrons
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.
