By What is the ground state electron configuration for Na+?
Examples: Na has a ground-state electronic configuration of 1s2 2s2 2p6 3s1. Removing the 3s electron leaves us with the noble gas configuration 1s2 2s2 2p6, so a sodium ion is Na+.
What is the most likely electron configuration for sodium ion Na +?
Stefan V. The electron configuration of a neutral sodium atom is 1s22s22p63s1 . In this configuration we note that there is only one electron in the 3rd energy level. Atoms prefer to gain the stability of octet, by having eight electrons in the outer shell, the electrons of the s and p orbitals.
How is an excited state electron configuration related to the ground state electron configuration?
The ground state configuration is the lowest energy, most stable arrangement. An excited state configuration is a higher energy arrangement (it requires energy input to create an excited state).
Which element has the ground state electron configuration Kr 5s1 4d5?
Explanation: And if Z=42 , the element is molybdenum , Mo .
What is the correct electron configuration for Na+?
[Ne] 3s¹
Sodium/Electron configuration
Which is the correct electron configuration for Mg2 +?
The enclosed electron configuration is the electron configuration of Neon (Ne), the nearest noble gas to Mg. Therefore, the correct noble gas electron configuration of Mg2+ is B. [Ne].
Which element has the electron configuration AR 4s2 3d10 4p3?
Arsenic
The element with atomic number 33 in the periodic table is Arsenic. Therefore, the given electronic configuration belongs to Arsenic.
Which element’s electron configuration ends in 4d5?
Is it easier to remove an electron from Na or Na+?
It’s easier to remove an electron from a positive ion rather than a negative. Na+ because it has more electrons than Mg2+. Magnesium has more protons, so its valence shell is pulled inwards. Explain why it is harder to remove an inner shell electron than a valence electron from an atom.
What is the ground state electron configuration for sodium?
The ground state electron configuration for sodium is: And the first excited state electron configuration for sodium is: This corresponds to an excitation to a first excited state that is less stable; that then leads to a relaxation back down to the ground state.
Which is an example of a ground state electron?
Example The ground state electron configuration of sodium is 1s22s22p63s1. In its excited state, the valence electron in the 3s sublevel is promoted to the 3p sublevel, giving the electron configuration as 1s22s22p63p1.
What does the excited state of an atom mean?
The excited state electron configuration of an atom indicates the promotion of a valence electron to a higher energy state.
Which is an example of an excited state of sodium?
As an example, sodium goes through a 3s→3p transition. The ground state electron configuration for sodium is: And the first excited state electron configuration for sodium is: This corresponds to an excitation to a first excited state that is less stable; that then leads to a relaxation back down to the ground state.
