For a 2s subshell to be present, the 1s subshell must first be full, which means no more electrons can be moved into the 1s subshell.

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.


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.


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 of the following is the correct electron configuration for Al (atomic number 13)?

The correct electron configuration for aluminum (Al), which has an atomic number of 13, is 1s² 2s² 2p⁶ 3s² 3p¹. This configuration indicates that aluminum has two electrons in the 3s subshell and one electron in the 3p subshell, following the filling order of the atomic orbitals.


What element Has 4 2p electrons?

The element with four 2p electrons is carbon. In its electron configuration, carbon has a total of six electrons, with two occupying the 1s orbital and four in the 2s and 2p orbitals. Specifically, the configuration is 1s² 2s² 2p², indicating that there are two electrons in the 2s subshell and two in the 2p subshell.


How many total electrons does an atom possess if it has the first two electron orbitals completed?

An atom with the first two electron orbitals completed would have 10 total electrons. The first electron orbital can hold up to 2 electrons (2 in the s subshell), and the second electron orbital can hold up to 8 electrons (2 in the s subshell and 6 in the p subshell).


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.


Why is the 2s subshell of heigher energy than the 1s subshell?

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.


Which sum gives the total number of electrons in electron configuration?

The sum from the exponents of the blocks.For instance,If We take the electron configuration of Sulfur (S) which is:1s22s22p63s23p4The total number of electrons i going to be 2 + 2 + 6 +2 + 4, which gives 16.


How many electrons in the 3p subshell in the ground state of atomic silicon?

In the ground state of atomic silicon, which has an atomic number of 14, there are a total of 14 electrons. The electron configuration is 1s² 2s² 2p⁶ 3s² 3p². Therefore, there are 2 electrons in the 3p subshell.


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.


How many 3d electron are in potassium?

Potassium (K) has an atomic number of 19, meaning it has 19 electrons. The electron configuration for potassium is 1s² 2s² 2p⁶ 3s¹. In this configuration, there are no electrons in the 3d subshell; therefore, potassium has 0 electrons in the 3d orbital.
