what element is represented by the electron configuration below? 1s² 2s² 2p⁶ 3s² 3p³\nphosphorus\nlithium\nar…

Brief Explanations:

To determine the element from an electron - configuration, sum the electrons. The sum of electrons in the given configuration (1s^{2}2s^{2}2p^{6}3s^{2}3p^{3}) is (2 + 2+6 + 2+3=15). Phosphorus has an atomic number of 15, which means it has 15 electrons. Lithium has 3 electrons and arsenic has 33 electrons.

Answer:

phosphorus
