Determine the total number of electrons, the number of valence electrons, and the name of the element with each electronic configuration. kr, 5s2, 4d1give correct answer
The electronic configuration "kr, 5s2, 4d1" represents the element Krypton (Kr) with a total of 36 electrons.
To determine the number of valence electrons, we focus on the outermost shell, which in this case is the 5th shell (indicated by the "5s2" part of the electronic configuration). The "s" subshell can hold a maximum of 2 electrons, so there are 2 valence electrons.
In summary:
- Total number of electrons: 36
- Number of valence electrons: 2
- Element: Krypton (Kr)
