Depending on what the level is, it may start filling d orbitals, or start on a new shell with s orbitals available.
The s orbital has the lowest energy level.
Briefly:The electrons are in orbitals, each orbital can take two electrons and each electron would have an opposite spin. Orbitals can have no electrons, one electron or be filled with two electrons.Orbitals are arranged in energy levels. However, even in the same energy level different orbitals will have different energy despite being in the same main energy level.The energy level nearest the nucleus has 1 orbital: 1sThe next energy level, the second energy level has four orbitals: 2s and three p orbitals. The 2p orbitals have more energy than the 2s orbital. The third energy level has 3s x1; 3p x 3 and 3d x 5 however, the 3d orbitals have an energy which actually places them in the fourth energy level between 4s and 4p. It gets complicated.
There are three p orbitals in all levels 2 and above. these are the px, py and pz orbitals, the (suffix is the direction - px lies along the x axis). In the 5th level they will be 5px, 5py, 5pz
The electrons in the outermost level are known as the valence electrons.
A carbon atom has four electrons in it's outermost energy level. Most atoms become stable when their outermost energy level contains eight electrons. A carbon atom therefore readily forms four covalent bonds with the atoms of other elements.
it converts into a bigger energy level
helium has completely filled valence orbitals and hence is stable
Carbon has four electrons in the outermost energy level, which is energy level two. It needs eight electrons to have this energy level filled.
Halogens have six valence electrons in the outermost energy level.
There is one s orbital and three p orbitals and five d orbitals in the third energy level.
valence electrons are the electrons in the outermost energy level
Outermost energy level is full if there are 8 electrons in the valence shell.
1st energy has 1 sublevel -- 1 orbital -- 2 electrons 2nd energy level has 2 sublevels -- 4 orbitals -- 8 e- 3rd energy level has 3 sublevels -- 9 orbitals -- 18 e- 4th energy level has 4 sublevels -- 16 orbitals -- 32 e- Notice the pattern? number of orbitals = energy level squared Number of electrons = 2x number of orbitals
4th energy level.
An atom with an incompletely filled outermost energy level is likely to be reactive. This is because it wants to acquire a filled outermost energy level.
The chloride ion (Cl-) has 8 electrons on the outermost energy level.
The principal quantum number, n, designates the main energy levels occupied by electrons. The number of orbitals in an energy level is n2 (n squared), so that the first energy level, n = 1, contains 1 orbital; the second energy level, n = 2, contains 4 orbitals; the third energy level, n= 3, has 9 orbitals; and the fourth energy level, n=4, has 16 orbitals, and so on.
