What elements have the same electron configuration?
When two different elements have the same electron configuration, they are called isoelectronic.
Which elements have a ground-state electron configuration?
Example 1 : What is the ground state electron configuration of carbon? Answer : Carbon is the 6th element in the periodic table, hence the atomic number Z = 6, and therefore has 6 electrons….

Do elements in the same group have similar electron configurations?
Elements in the same GROUP have similar electron configurations. This means there are seven valence electrons. 6.
Which three elements have the same electron configuration as AR?
And we can see that the potassium ion, K+, has the same electronic configuration as the chloride ion, Cl-, and the same electronic configuration as an atom of argon, Ar. Therefore, Ar, Cl-, and K+ are said to be isoelectronic species.
What is the ground state electron configuration of SE?
The ground state electronic configuration of Neutral Selenium atom is [Ar] 3d10 4s2 4p4.
Which elements are most similar to each other those in the same period or those in the same group Why?
This is because the chemicals properties depend on no of valence electrons. As in a group all elements have same no of valence electron that’s why they have similar chemical properties but in a period the no of valence electron varies that’s why they differ in chemical properties.
What is similar about elements in the same period?
Elements in the same period have the same number of electron shells; moving across a period (so progressing from group to group), elements gain electrons and protons and become less metallic. This arrangement reflects the periodic recurrence of similar properties as the atomic number increases.
What ion has the same electron configuration as he?
Li+
The electron configuration of Li+ becomes 1s2 . That’s the same electron configuration as for He . The electron configuration of Mg is 1s22s22p63s2 . The electron configuration of Mg2+ is 1s22s22p6 .
Which element has the electron configuration of 1s 2 2s 2 2p 6 3s 2 3p 4?
| Element | Atomic number | Electron configuration |
|---|---|---|
| silicon | 14 | 1s22s22p63s23p2 |
| phosphorus | 15 | 1s22s22p63s23p3 |
| sulfur | 16 | 1s22s22p63s23p4 |
| chlorine | 17 | 1s22s22p63s23p5 |
Can two elements have the same electron configuration with different numbers of electrons?
You can’t have the same electron configuration with different numbers of electrons. However, if you allow ionization, then it is possible. For example, oxide ion, fluoride ion, neon, sodium ion, magnesium ion and aluminum ion all have the same ground-state electron configuration: 1 s² 2 s² 2 p⁶.
What is the ground-state electron configuration of an oxide ion?
For example, oxide ion, fluoride ion, neon, sodium ion, magnesium ion and aluminum ion all have the same ground-state electron configuration: 1s² 2s² 2p⁶.
Do all isotopes have the same electronic configuration?
Isotopes have same electronic configuration. Isotope are those elements which have same atomic number but different mass number. Since isotope have same number of electrons, so they have same electronic configuration. All isoelectronic species have same electronic configuration.
