Question

which two of the following electronic configurations (in quantum mechanical notation) are not reasonable? indicate the letters of the two unreasonable electronic configurations: . a) 1s22s22p4 b) 1s22s22p73s23p4 c) 1s22s22p63s23p5 d) 1s22s62p5

Answer 1

1s²2s²2p⁷3s²3p⁴ two of the following electronic configurations (in quantum mechanical notation) are not reasonable.

The correct option is B.

How do you find the electron configuration?

Using subshell labels, the electronic structure of an atom is described. These labels include the subshell name, which is determined by the azimuth and elevation quantum number, the shell number, which is determined by the main quantum number, and the total quantity of electrons in the subshell, which is indicated in superscript.

What three factors influence electronic configuration?

An atom's electron configuration describes how its electrons are dispersed across its orbits (shells) and subshells. An atom's electron configuration is crucial because it aids in predicting a substance's chemical, physiological, electrical, and magnetic characteristics.
