You need to state how many atoms are in the 4s. I.e. is it 4s1 i.e. Potassium, or 4s2 i.e. calcium

Sodium and calcium each have the same number of orbitals. These two elements (in their neutral, ground state) have 6 electron orbitals: 1s, 2s, 2px, 2py, 2pz, 3s.
Atomic nitrogen has 5 valence electrons and 4 valence orbitals (2s, 2px, 2py, and 2pz). In the Lewis structure there is a triple bond between the nitrogen atoms and non-bonding pair of electrons on each. This consist with the physical properties of N2.
All three 2p orbitals (2px, 2py, 2pz) are occupied by two electrons each.(6 electrons in total: (2px2, 2py2, 2pz2) = 2p6)
When you fill an orbital the electrons must spin in opposite directions. This results in no two electrons having the same quantum number, a result defined as the Pauli Exclusion Principle. You can have 2 electrons in an orbital. Note that 2py 2px and 2pz are three different orbitals.
Energy difference in N2 2s orbital and 2Px orbital is very low due to which they mix with each other.2s give its energy to 2Px, 2Px gain more energy and became unstable and increase its energy, and jump above on the 2Pz, 2Py orbitals in MOT diagram.now ALL 4 atomic orbitals i.e 2s sigma, 2s sigma star ,2Px sigma,2Px sigma star donot have thier own pure characters. other orbitals donot take part in mixingNOTE:this phenomena is for elements having atomic number up to 7OXYGEN have atomic number 8. it energy differences b/w orbitals is large.That's why its MOT diagram is different.
three...2px,2py,and 2pz.
Yes. The 2s, 2px, 2py and 2pz .
Sodium and calcium each have the same number of orbitals. These two elements (in their neutral, ground state) have 6 electron orbitals: 1s, 2s, 2px, 2py, 2pz, 3s.
Assuming K stands for potassium, an element with 19 electrons, the electron configuration is as follows: 1s2 2s2 2p6 3s13p64s1 The electron configuration shows the orbitals is order of energy level. The 4s orbital being at the highest energy level and the 1s orbital being at the lowest energy level. As 2px, 2py and 2pz exist, there are three 2p orbitals that occur at the p level, allowing the element to carry 6 electrons, 2 in each orbital. There is a specific order in listing the orbitals
2s, 2p. 2s contains 1 orbital, the 2p sublevel contains 3 orbitals 2px 2py, 2pz where the suffix is the direction the orbital lies in, 2px lies on the x axis.
Nitrogen (N) has atomic number 7. It has full 1s and 2s orbitals. The 2px orbital has 1 electron, the 2py orbital has 1 electron and the 2pz orbital has 1 electron. So the valence shell is: 2s2 - 2p3. It contains 5 electrons.
Molecular Orbital Theory (MOT):•Basic idea of MOT is that atomic orbitals of individual atoms combine toform molecular orbitals. Electrons in molecule are present in themolecular orbitals which are associated with several nuclei.•The molecular orbital formed by the addition of atomic orbitals is calledthe bonding molecular orbital (s ).•The molecular orbital formed by the subtraction of atomic orbital is calledanti-bonding molecular orbital (s*).•The sigma (s ) molecular orbitals are symmetrical around the bond-axiswhile pi (p ) molecular orbitals are not symmetrical.•Sequence of energy levels of molecular orbitals changes for diatomicmolecules like Li2, Be2, B2, C2, N2 is 1s < *1s < 2s< *2s < ( 2px = 2py)
Atomic nitrogen has 5 valence electrons and 4 valence orbitals (2s, 2px, 2py, and 2pz). In the Lewis structure there is a triple bond between the nitrogen atoms and non-bonding pair of electrons on each. This consist with the physical properties of N2.
The second period (row) on the periodic table consists of elements that are filling the 2nd energy level, from 2s1 in lithium to 2s22p6 in neon.
All three 2p orbitals (2px, 2py, 2pz) are occupied by two electrons each.(6 electrons in total: (2px2, 2py2, 2pz2) = 2p6)
When you fill an orbital the electrons must spin in opposite directions. This results in no two electrons having the same quantum number, a result defined as the Pauli Exclusion Principle. You can have 2 electrons in an orbital. Note that 2py 2px and 2pz are three different orbitals.
When two carbon atoms are linked by a triple bond, one will be a sigma bond (formed by the 2px-px overlap of the two carbon atoms) whereas the other two will be pi bonds (formed by the 2py-py overlap and 2pz-pz overlap of the two carbon atoms).
