it is just a quantum property, its further away from the nucleus

The 2s subshell has a higher energy level than the 1s subshell due to the presence of more nodes in the 2s orbital, which increases its energy. Additionally, the 2s orbital has a larger principal quantum number (n) than the 1s orbital, leading to greater distance from the nucleus and therefore higher energy.

Why is transfer of electron from 2s subshell to 1s subshell not possible?
Transfer of an electron from a higher energy orbit (2s) to a lower energy orbit (1s) is not possible because it would violate the energy conservation principle. Electrons naturally occupy the lowest available energy levels in an atom, following the Aufbau principle. This means electrons will only move to higher energy levels if they absorb energy, not by transferring between lower and higher energy levels.
How can you tell the difference between 1s subshell and 3s subshell?
The principal quantum number (n) distinguishes between different subshells. For example, the 1s subshell has an n value of 1, while the 3s subshell has an n value of 3. The higher the n value, the higher the energy level of the subshell.
Why are electrons in the 1s subshell much closer to the nucleus in Ar than in He?
Electrons in the 1s subshell are closer to the nucleus in Ar than in He due to the greater nuclear charge in argon (Ar) compared to helium (He). Ar has more protons in its nucleus, creating a stronger attraction for the electrons in the 1s subshell, pulling them closer to the nucleus.
What atom is represented in the following orbital diagram 1s2s2p?
The atom represented in the orbital diagram 1s2s2p is carbon (C). This notation indicates the electron configuration of carbon, where the 1s subshell is filled with 2 electrons, followed by 2 electrons in the 2s subshell and 2 electrons in the 2p subshell.
All of the orbitals in a subshell have the same energy?
This is true for orbitals within the same subshell (s, p, d, f), as they all have the same principal quantum number. However, as you move to higher energy levels, the energy of the orbitals within a subshell can differ slightly due to shielding and other factors.

What is the subshell of the K shell?
The K shell is the first shell in an atom and has only one subshell, which is the 1s subshell. This subshell can hold up to 2 electrons.
Why are electrons in the 1s subshell much closer to the nucleus in Ar than in He?
Electrons in the 1s subshell are closer to the nucleus in Ar than in He due to the greater nuclear charge in argon (Ar) compared to helium (He). Ar has more protons in its nucleus, creating a stronger attraction for the electrons in the 1s subshell, pulling them closer to the nucleus.

The atom represented in the orbital diagram 1s2s2p is carbon (C). This notation indicates the electron configuration of carbon, where the 1s subshell is filled with 2 electrons, followed by 2 electrons in the 2s subshell and 2 electrons in the 2p subshell.
How a 1s orbital different from a 2s orbital in terms of size?
The 2s orbital is larger than the 1s orbital and is higher in energy.
All of the orbitals in a subshell have the same energy?
This is true for orbitals within the same subshell (s, p, d, f), as they all have the same principal quantum number. However, as you move to higher energy levels, the energy of the orbitals within a subshell can differ slightly due to shielding and other factors.
What does the 1s mean?
The term "1s" typically refers to the orbital energy level in an atom. It represents the first energy level or shell where electrons are located. In the 1s orbital, electrons are closest to the nucleus and have the lowest energy.
Actually carbon valency written as 1s2 2s2 2p2.why not this is write as 1s2 2s1 2p3?
Carbon has 4 valence electrons, which are distributed as 2 in the 2s orbital and 2 in the 2p orbital. The notation 1s^2 2s^2 2p^2 indicates the distribution of electrons in the 1s, 2s, and 2p orbitals, with 2 electrons in the 1s orbital, 2 in the 2s orbital, and 2 in the 2p orbital. It is not written as 1s^2 2s^1 2p^3 because electrons pair up in orbitals before filling them singly, following the Aufbau principle.
The major difference between a 1s orbital and a 2s orbital is that?
the 1s orbital is closer to the nucleus and has a lower energy level compared to the 2s orbital. Additionally, the 2s orbital has a slightly higher energy, larger size, and can hold more electrons than the 1s orbital.
He highest level of occupied energy in element?
1s
How does 2s orbital differ from a 1s orbital?
1s and 2s orbitals differ in that 2s orbitals lie farther away from the nucleus in the next principle energy level. Other than that, they occupy the same shape of orbital, spherical, as indicated by the s.
