Which one of the following sets contains species that have the same electronic configuration?Group of answer choicesC4-, N3-, O2-F, Ne, NaSe-, Br-, Kr-P3+, S2-, ArCl, Ar, K

The species that have the same electronic configuration are C4-, N3-, O2-.

Here's why:

1. The electronic configuration of an atom is determined by the number of electrons in its atomic orbitals.

2. In a neutral atom, the number of electrons is equal to the number of protons in the nucleus.

3. When an atom gains or loses electrons, it becomes an ion and its electronic configuration changes.

4. C4- means that the carbon atom has gained 4 electrons, N3- means that the nitrogen atom has gained 3 electrons, and O2- means that the oxygen atom has gained 2 electrons.

5. The atomic numbers of carbon, nitrogen, and oxygen are 6, 7, and 8 respectively.

6. Therefore, C4- has 6 + 4 = 10 electrons, N3- has 7 + 3 = 10 electrons, and O2- has 8 + 2 = 10 electrons.

7. Since they all have 10 electrons, they have the same electronic configuration.
