choose the element that has the electron - configuration of 1s²2s²2p⁶3s²3p¹ by selecting the appropriate box on the table. periodic table of elements
Answer
Explanation:
Step1: Determine the total number of electrons
The electron - configuration is (1s^{2}2s^{2}2p^{6}3s^{2}3p^{6}4s^{2}3d^{10}4p^{4}). Add up the exponents: (2 + 2+6 + 2+6 + 2+10 + 4=34).
Step2: Identify the element based on atomic number
The atomic number of an element is equal to the number of electrons in a neutral atom. The element with atomic number 34 is Selenium (Se).
Answer:
Se
