🔥EXPLANATION:🔥 Niels Bohr’s 1913 model pictured electrons as tiny charged particles orbiting the nucleus in fixed, circular paths. In the following years, several scientists, including Werner Heisenberg came to the Institute for Theoretical Physics in Copenhagen (later known as Bohr Institute) where Bohr explained his models. However, in 1925, Heisenberg began to contribute to quantum mechanics, ultimately devising his famous uncertainty principle in 1927. . . . . . . . . #chemistrymemes #phys
