electron configuration assignment\nwhat is the element is shown by the electron configuration below?\n1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰ 4p⁶ 5s²
Answer
Explanation:
Step1: Count the total number of electrons
The superscripts represent the number of electrons in each orbital. Add them up: $2 + 2+6 + 2+6 + 2+10 + 6+2=38$.
Step2: Identify the element
The atomic number of an element is equal to the number of electrons in a neutral atom. Looking at the periodic - table, the element with atomic number 38 is strontium (Sr).
Answer:
Sr
