You appear to mean silicon. Please see the link.
It has 2 unpaired electrons and 8 empty electron levels.
It depends on the atom.Atoms may have up to three energy levels, or layers of electrons, although some elements, such as helium, have only one. If an atom has one energy level, its valence electrons may total up to only two. If it has two or three energy levels, It may have up to eight total valence electrons. An atom is neutral when it has the greatest possible number of electrons.
Electrons are located in energy levels within the electron cloud.
The element magnesium has four electron energy levels and two electrons in its outer energy level in the neutral atom. Use the link to Wikipedia for more details.
That is correct. Titanium has 22 electrons, and its highest full orbital is 4s and the 3d is partially filled with 2 electrons. So Titanium is 1s22s22p63s23p64s23d2
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.
Sodium
Phosphorus, I think. 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.
