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.
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).
Aluminum has 3 electrons in its highest occupied energy level.
2nd energy level, the electron arrangement is 2,1 at ground state
the first energy levels hold 2, 8, and 18 a total of 28 electrons
The third and higher energy levels can hold more than 8 electrons. The third energy level has 18 electrons, the fourth has 32, and so on. Each successive energy level can hold more electrons than the one before it.
Phosphorus has five electrons in the third energy level (n=3).
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).
Nitrogen has 7 electrons in total. In its ground state, nitrogen has two electrons in the 1s orbital and five electrons in the 2p orbital. Therefore, there are 3 electrons in the higher energy level (2p orbital) of nitrogen.
Aluminum has 3 electrons in its outermost energy level.
Aluminum has 3 electrons in its highest occupied energy level.
Lithium has a total of 3 electrons. The first energy level of an atom can hold a maximum of 2 electrons, so the first energy level of lithium will have 2 electrons.
Phosphorus has 5 electrons in its highest occupied energy level.
2nd energy level, the electron arrangement is 2,1 at ground state
