If the S orbital has two electrons and the P orbital has six you go on to the D orbital. Electron energy levels follow this format:
1s2 2s2 2p6 3s2 3p6 4s2 4p6 4d10 and so on

When do orbitals start getting filled?
after the s orbital of the next highest energy level
Why are the noble gases not included in the trend in ionization energy?
Noble gases have completely filled orbitals are are stable. they do not donate electrons and hence are not included in ionization energy trend.
The order in which atomic orbitals are filled is based on what factor?
It is based on many factors, but the easiest to understand is ENERGY. The orbitals in which the electron has the lowest energy are filled FIRST.
Why does 4s orbital start filling while 3p orbital is empty?
The electrons fill in the lowest energy orbital that is available. Electrons in the 4s orbital have a lower energy level than electrons in the 3p orbital, so the 4s orbitals are filled with electrons first.
How many electrons do the noble gases have in there outer energy levels?
8, with the exception of helium which has 2.
When do orbitals start getting filled?
after the s orbital of the next highest energy level
How many unpaired electrons does phosphorus have in its 3p sub level?
3. Orbitals are filled one electron at a time, putt ting electrons into the lowest energy orbitals first. When there are degenerate orbitals ( having the same energy e.g. p and d orbitals) they tale one un paired electron each first and then and then any extra electrons are added into a half filled orbital to make a spin pair. P has a configuration of [Ne] 3s2 3p3 and there are only three p orbitals ( at any energy level)
When 3 d orbitals are completely filled the new electrons will enter in?
After the 3d sublevel is filled, additional electrons will occupy the 4p orbitals, for a total of 6 electrons in the 4p sublevel.
When do D orbitals start gettin filled?
D orbitals begin being filled with electrons after the orbital found in the 4s sublevel is filled.
What is the maximum number of d ortitals in a principal energy level?
D has 5 orbitals and can be filled with up to 10 electrons.
How many s orbitals are filled with electrons in a cadmium atom?
Cadmium is a d block metal element. Atomic number of it is 48. It has 5 s orbitals filled with electrons.
Where does electron exist in an atom?
Electrons exist in the electron cloud that surrounds the nucleus of an atom. This cloud is made up of the various orbitals that hold the electrons. Orbitals are regions of space in which the probability of finding an electron is the highest. The electrons orbit the nucleus in these orbitals and can move from one orbital to another as they gain or lose energy. 1s Orbital: This orbital is closest to the nucleus and can hold up to two electrons. 2s Orbital: This orbital is farther away from the nucleus and can hold up to two electrons. 2p Orbitals: These orbitals are even farther away from the nucleus and can hold up to six electrons. 3s Orbital: This orbital is farthest away from the nucleus and can hold up to two electrons. 3p Orbitals: These orbitals are even farther away from the nucleus and can hold up to six electrons. 3d Orbitals: These orbitals are the farthest away from the nucleus and can hold up to ten electrons.These orbitals are filled in a specific order with the 1s orbital being filled first then the 2s 2p 3s 3p and finally the 3d orbitals. The electrons in the outermost orbitals are called valence electrons and are responsible for the chemical properties of the atom.
How does the band theory of metallic bonding explain the luster of metals?
According to the band theory, any given metal atom has only a limited number of valence electrons with which to bond to all of its nearest neighbours. Extensive sharing of electrons among individual atoms is therefore required. This sharing of electrons is accomplished through the overlap of atomic orbitals of equivalent energy on the metal atoms that are immediately adjacent to one another. This overlap is delocalized throughout the entire metal sample to form extensive orbitals that span the entire solid rather than being part of individual atoms. Each of these orbitals lies at different energies because the atomic orbitals from which they were constructed were at different energies to begin with. The orbitals, equal in number to the individual atomic orbitals that have been combined, each hold two electrons, and are filled in order from the lowest to the highest energy until the number of available electrons has been used up. Groups of electrons are then said to reside in bands, which are collections of orbitals. Each band has a range of energy values that the electrons must possess to be part of that band; in some metals, there are energy gaps between bands, meaning that there are certain energies that the electrons cannot possess. The highest energy band in a metal is not filled with electrons because metals characteristically possess too few electrons to fill it. The high thermal electrical conductivities of metals is then explained by the notion that electrons may be promoted by absorption of thermal energy into these unfilled energy levels of the band.
How many outer orbital electrons are found in an atom of nitrogen?
Nitrogen has 5 valence electrons. Valence electrons are the electrons that are found in the outer most shell of an atom, and are consequently the electrons that move from atom to atom in the formation of compounds. The reason for this is a result of the electron configuration. A nitrogen atom has 3 orbitals; the 1s orbital, the 2s orbital, and the 2p orbital. In this case, the 2s and 2p orbitals are the valence orbitals, as they have the electrons with the most energy. With 7 protons, a neutral nitrogen atom has 7 electrons. The s orbitals can only hold 2 electrons, and the p orbitals can hold up to 6 electrons. The 1s orbital is filled first, leaving five electrons, then the 2s orbital is filled, leaving 3 electrons, and then these remaining electrons fill the 2p orbital halfway. There are a total of 5 electrons in the 2s and 2p orbitals, and since these orbitals have the most energy, there are 5 valence electrons.
Why is a helium atom stable with only two electrons in its outermost energy level?
helium has completely filled valence orbitals and hence is stable
Why are the noble gases not included in the trend in ionization energy?
Noble gases have completely filled orbitals are are stable. they do not donate electrons and hence are not included in ionization energy trend.
What is aufboud principle?
The Aufbau principle states that electrons will fill up the different orbitals in an atom in order, i.e. the s orbitals of an atom will be filled by electrons before the p orbitals.
