A 2s subshell and a 2p subshell can be distinguished by their shape and energy levels. The 2s subshell is spherical and has a lower energy than the 2p subshell, which has a dumbbell shape and is oriented along specific axes (x, y, z). Additionally, the 2s subshell can hold a maximum of 2 electrons, while the 2p subshell can hold up to 6 electrons. These differences in shape, energy, and electron capacity help identify each subshell.
You can tell the difference between a 2s sub-shell and 2p sub-shell from their energy levels, because a 2p sub-shell is a higher energy level than a 2s sub-shell.
You can differentiate between a 2s and a 2p subshell based on their shape. The 2s subshell is spherically symmetric and has one orbital. On the other hand, the 2p subshell has a dumbbell shape and consists of three orbitals: px, py, and pz, each oriented along separate axes.
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.
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.
The second period (row) on the periodic table consists of elements that are filling the 2nd energy level, from 2s1 in lithium to 2s22p6 in neon.

The 2s subshell has a spherical shape and can hold a maximum of 2 electrons, while the 2p subshell has a dumbbell shape and can hold a maximum of 6 electrons. Additionally, the 2p subshell consists of three orbitals (labeled px, py, pz), while the 2s subshell consists of only one orbital.

In a lithium atom, the energy of the 2s subshell is lower than the energy of the 2p subshell.
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.
The third subshell, which is the 2s and 2p subshells, can hold a maximum of 8 electrons.
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.
The second period (row) on the periodic table consists of elements that are filling the 2nd energy level, from 2s1 in lithium to 2s22p6 in neon.
In the shell with principal quantum number ( n = 2 ), there are two subshells: the 2s subshell and the 2p subshell. Each subshell corresponds to a different angular momentum quantum number ( l ); for 2s, ( l = 0 ), and for 2p, ( l = 1 ). Therefore, the shell with ( n = 2 ) contains a total of two subshells.
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.
Two electrons can occupy the 2s subshell, and 8 electrons can occupy the 3d subshell.
First of all this is not Carbon's valency, it is electronic configuration or arrangement of electrons around nucleus. Electron filling takes place by Aufbau principle. Explanation: Electrons around an atom are arranged in shells( denoted by n) numbered 1, 2, 3, and so on. Each of these shells is further divided into s,p,d,f subshells(denoted by l). It is known that electrons in a subshell have same energy. Electron filling occurs 1st in subshells of lower energy and higher energy subshell is filled only after the lower subshell is completely filled (Aufbau principle). Subshell whose n+l sum is less has lower energy. So here 2s(n+l=2) shell is lower to 2p(n+l=3), and 2s can have 2 electrons so after 2s is filled 2 electrons left go to 2p subshell.
