Nitrogen (N) is atomic number 7, so has 7 electrons in the ground state. The configuration is1s2 2s2 2p3. From this, one can see that the 1s is full, as is the 2s. So, the number of completely filled orbitals is TWO.

Why the size of atom does not decrease regularly in a period?

Which atom is more chemically reactive an atom with a partly filled energy level or an atom with all energy levels completely filled and why?
If all the electron orbitals are filled then the atom is inert. It will not chemically react with anything. If an atom has empty spaces in the outer orbit, it will react with other elements. Electrons from other elements can share positions in the outer orbits.
Why is helium atomic number 2?
Helium's atomic number is 2 because it has 2 protons in its nucleus.
Are noble gases more likely to exist in nature as molecule or single atom?
Noble gases have completely filled orbitals. Their valence orbitals are completely filled, have 8 electrons and obey octet rule (stable electronic configuration). Hence they are chemically inert (or do not react with other elements), they do generally do not form compounds and are mono atomic.
Why is helium atom more stable than hydrogen atom?
Hydrogen has 1 proton and 1 electron, helium has 2 protons, 2 neutrons and 2 electrons.
How many orbitals are completely filled in an atom of an element whose atomic number is 19?
Three completely filled orbitals.
What is the result of sodium atom transferring an electron to a chlorine atom and they become stable?
The result is what you use to put in the food. Table salt (or sodium chlorine). It's a very stable compound, as each of the ions have their orbitals completely filled. Recall that in their normal states, Sodium has only one valence electron, and the Clorine is missing one to have its orbitals filled.
Is helium considered a complete atom?
Yes it is, as it has completely filled s orbitals.
How many orbitals are completely filled in an atom whose electron configuration is 1s2 2s2 2p3?
Two orbitals.
Is argon a reactive atom?
No. argon is chemically unreactive due to the presence of completely filled orbitals.
How many orbitals are completely filled in an atom of chromium?
1s2 2s2 2p6 3s2 3p6 3d5 4s1 So 5 full orbitals and a half filled 3d orbital
How many orbitals are completely filled in an atom whose electron configuration is 1s2 2s2 2p6 3s1?
5
What do atoms of less reactivity tend to have?
For one, the atom's outer circle is completely filled with the maximum number of electrons - it's valence orbitals are filled.
How many orbitals completely filled in an atom whose wlectron configuration is 1s2 2s2 2p6 3s1?
That would be 1s2, 2s2, 2p6 are the 3 orbitals that are completely filled. The other one is not filled because it only has 1 configuration. Hopefully this help....if not I apologize. *PUMA #4*
What determines the number of hybrid orbitals produced by an atom?
Half filled orbitals or empty orbitals
How many filled orbitals are in an atom of sulfur?
2 full orbitals, S and P
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
