Interpretation:
The sphere which represents ion is to be identified among given.
Concept Introduction :
The electron configuration of an element defines how its electrons are arranged throughout its atomic orbitals. Standard notation is used to represent atomic electron configurations, placing all electron-containing atomic subshells in sequential order. The number of electrons held by the subshell is indicated by superscript.
Answer to Problem 4STP
Sphere A
Explanation of Solution
The
Potassium has 19 electrons which is one more than the Nobel gas electronic configuration
By losing one electron, no. of electrons decreases but the nuclear charge stays unchanged. So, electrons are held more tightly by the positively charged protons, which leads to a decrease in the size of the ion compared to the atom.
Thus, sphere A represents potassium ion.
