what atom matches this electron configuration? 1s²2s²2p⁶3s²3p⁶4s²3d¹⁰
what atom matches this electron configuration? 1s²2s²2p⁶3s²3p⁶4s²3d¹⁰
Answer
Explanation:
Step1: Calculate the total number of electrons
The electron configuration is (1s^{2}2s^{2}2p^{6}3s^{2}3p^{6}4s^{2}3d^{10}). Sum the exponents: (2 + 2+6 + 2+6 + 2+10=30).
Step2: Determine the element based on atomic number
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 (30) is Zinc ((Zn)).
Answer:
Zinc
