How many orbitals are completely filled in an atom whose electron configuration is 1s2 2s2 2p6 3s1?
There are two completely filled orbitals in this atom: the 1s orbital with 2 electrons and the 2p orbitals with 6 electrons. The 2s orbital and 3s orbital are not completely filled.
How many orbitals are completely filled in an atom whose electron configuration is 1s2 2s2 2p3?
There are two orbitals that are completely filled in this atom: the 1s orbital with 2 electrons (1s2) and the 2s orbital with 2 electrons (2s2). The 2p orbital is not completely filled, as it should have a total of 6 electrons (2p6).
How many unpaired electrons does germanium have in its ground state?
Germanium has 0 unpaired electrons in its ground state, as it has a completely filled 4s and 4p orbitals, resulting in a full outer shell configuration.
When 3 d orbitals are completely filled the new electrons will enter in?
When the 3d orbitals are completely filled, the new electrons will enter the 4s orbital before filling the 3d orbitals. This is because the 4s orbital has a lower energy level than the 3d orbitals, making it the first choice for accommodating additional electrons.
Which of the 2 outermost orbitals must be filled to satisfy the octet rule?
The 2 outermost orbitals that must be filled to satisfy the octet rule are the s and p orbitals. These orbitals can hold a maximum of 8 electrons in total, which is needed to achieve a stable, full octet configuration for many elements.
Why do noble gases have a stable electon configuration?
because they have completely filled orbitals
How many orbitals are completely filled in an atom whose electron configuration is 1s2 2s2 2p6 3s1?
There are two completely filled orbitals in this atom: the 1s orbital with 2 electrons and the 2p orbitals with 6 electrons. The 2s orbital and 3s orbital are not completely filled.
How many orbitals are completely filled in an atom of sodium?
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.
How many orbitals are completely filled in an atom whose electron configuration is 1s2 2s2 2p3?
There are two orbitals that are completely filled in this atom: the 1s orbital with 2 electrons (1s2) and the 2s orbital with 2 electrons (2s2). The 2p orbital is not completely filled, as it should have a total of 6 electrons (2p6).
Why are noble gases the most nonreactive?
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).
Why is it that the noble gas group is strongly stable?
Noble gases have completely filled orbitals. Their valence orbitals are completely filled, have 8 electrons and obey octet rule (stable electronic configuration). They are chemically inert (or do not react with other elements).
What orbitals electrons always add to the valence shell?
Because the inner shell already has completely filled electronic configuration.
How many orbitals are completely filled in an atom of an element whose atomic number is 19?
Three completely filled orbitals.
Why doesnt neon take or give electrons?
neon has completely filled orbitals, obeys octet and has stable electronic configuration. Hence it does not take or give electrons.
Why do atoms in neon gas do not join?
Neon has completely filled orbitals, has stable electron configuration and hence neon atoms do not bind / join with each other.
Do noble gases occur in diatomic form?
No. Noble gases have completely filled valence orbitals, have stable electronic configuration. Hence they exist as monoatomic species.
When elements are stable?
Elements are stable when they have completely filled (or half filled) orbitals.
