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?
It is due to the increased in the effective nuclear charge in argon. Helium has 2 protons in its nucleus. On the other hand, argon has 18 protons in its nucleus.Therefore, it has greater attractive power. Due to this, all the electrons are pulled closer to 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?
Orbitals having the same first two quantum numbers are degenerate ... they have the same energy ... in the absence of a magnetic field.So all 1s orbitals in a given atom have the same energy, all 3d orbitals in a given atom have the same energy, etc.In a magnetic field, the spin degeneracy is removed, so that "spin up" and "spin down" electrons have different energies, even if they're in the same orbital.

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.
What is the electon configuration of 15p?
The electron configuration of phosphorus (atomic number 15) is 1s² 2s² 2p⁶ 3s² 3p³. This indicates that phosphorus has two electrons in the 1s subshell, two in the 2s subshell, six in the 2p subshell, two in the 3s subshell, and three in the 3p subshell. The configuration reflects its position in the periodic table and its chemical properties.
9 electrons How would these electrons be arranged?
For an atom with 9 electrons, such as fluorine, the electron configuration would be 1s² 2s² 2p⁵. This means that the first energy level (1s) contains 2 electrons, and the second energy level contains 2 electrons in the 2s subshell and 5 electrons in the 2p subshell. The arrangement reflects the Aufbau principle, where electrons fill the lowest energy orbitals first before moving to higher ones.
Why are electrons in the 1s subshell much closer to the nucleus in Ar than in He?
It is due to the increased in the effective nuclear charge in argon. Helium has 2 protons in its nucleus. On the other hand, argon has 18 protons in its nucleus.Therefore, it has greater attractive power. Due to this, all the electrons are pulled closer to nucleus.
What Has five electrons in the n 3 energy level?
An atom with five electrons in the n = 3 energy level is typically phosphorus (P), which has the electron configuration of 1s² 2s² 2p⁶ 3s² 3p³. In this configuration, the 3s subshell contains 2 electrons, and the 3p subshell contains 3 electrons, totaling five electrons in the third energy level.
What element has five electrons in energy level n3?
The element with five electrons in the third energy level (n=3) is phosphorus (P). In its electron configuration, phosphorus has the atomic number 15, with the distribution of electrons as 1s² 2s² 2p⁶ 3s² 3p³. Thus, it has five electrons in the third energy level (2 in the 3s subshell and 3 in the 3p subshell).
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.
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.
Is 1s22s22p63s23p64s24d104p5 valid?
No, the electron configuration 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 4d¹04p⁵ is not valid because it incorrectly suggests that the 4d subshell is filled before the 4p subshell. In the correct order of filling, the 4p subshell would be filled after the 4s and 3d subshells, so the proper configuration for an element with atomic number 35 (bromine) is 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰ 4p⁵.
What is the correct electron configuration for an element with 5 electrons?
The correct electron configuration for an element with 5 electrons, which is boron (B), is 1s² 2s² 2p¹. This indicates that the first energy level (1s) contains two electrons, the second energy level (2s) contains two electrons, and one electron is in the 2p subshell. Thus, the total adds up to five electrons.
