Element 109, now named meitnerium (in honor of the Austrian-Swedish physicist, Lise Meitner [1878-1968]), was produced in August 1982 by a team at Germany's Institute for Heavy Ion Research. Depict its electron configuration using spdf and noble gas notations. Lise Meitner (1878-1968) and Otto Hahn (1879-1968). Ele- ment 109 (Mt) was named after Meitner. She earned her Ph.D. in physics under Ludwig Boltzmann at the University of Vienna, and she was the first woman to earn a Ph.D. at that university. (Express your answer as a series of orbitals. For example, the electron configuration of Li would be entered in complete form as 1s ² 2s ¹ or in condensed form as [He]2s ¹.) spdf notation configuration: Noble gas notation configuration: Name another element found in the same group as meitnerium.

C Express your answer in complete form in the order of orbital filling as a string without blank space between orbitals. For example, 1s22s21s22s2 should be entered as 1s^22s^2.   P Express your answer in complete form in the order of orbital filling as a string without blank space between orbitals. For example, 1s22s21s22s2 should be entered as 1s^22s^2.   Ar Express your answer in complete form in the order of orbital filling as a string without blank space between orbitals. For example, 1s22s21s22s2 should be entered as 1s^22s^2.   NaNa Express your answer in complete form in the order of orbital filling as a string without blank space between orbitals. For example, 1s22s21s22s2 should be entered as 1s^22s^2.
