Question

The atomic number of an element is 2.0. it's electronic configuration is​

Answer 1

Answer:

The atomic number of Ar s 18, so its electronic configuration is 2,8,8 (it has 8 valence electrons). Thus, neither element P (phosphorus) nor Ar (argon) have 7 valence electrons in their atoms.

Answer 2

Answer:

The atomic number of P is 5, so its electronic configuration is 2,8,5 (it has 5 valence electrons). The atomic number of Ar s 18, so its electronic configuration is 2,8,8 (it has 8 valence electrons). Thus, neither element P (phosphorus) nor Ar (argon) have 7 valence electrons in their atoms.
