What is the neutral atom that has its first two energy levels filled, has 5
electrons in its third energy level, and has no other electrons? Enter the name of the element, not the abbreviation.
A sulfur atom.
Phosphorus, I think. Please see the link.
the element sodium has 1,000,000 million energy levels.
Carbon has 2 energy levels. There are 6 electrons, 6 protons, and 6 neutrons.
in the energy levels. energy levels are in the electron cloud.
8 electrons.
Sodium
Phosphorus, I think. Please see the link.
You appear to mean silicon. Please see the link.
Chlorine.
The innermost energy level always contains two electrons and the rest are arranged in 8s. for example the energy levels of calcium- 2,8,8,2. calcium contains 20 electrons. once the energy levels are filled upto 8 electrons then we move from onto the next energy level. hope this makes sense lol :)
Neon has the 1s2, 2s2, and 2p6 levels filled.
The first 3 energy levels are filled, the 4s and 4p and 4d sublevels are filled, and the 5s and 5p sublevels are also filled. So only the first three energy levels are completely filled. The fourth and fifth energy levels are partly filled. The electron configuration is 1s22s22p63s23p63d104s24p64d105s25p6 or [Kr]4d105s25p6.
1s2 2s2 2p6 3s2 3p3
Yes, it has 5 energy levels as it belongs to group 5. The 54 electrons in xenon are filled in these energy levels as 2, 8, 18, 18, 8
the element sodium has 1,000,000 million energy levels.
If by energy levels you mean shells then Beryllium (Be) is in the second group and the second Period.
It has 2 unpaired electrons and 8 empty electron levels.
