Which scientist is recognized for creating a more accurate model of the atom?

Neils Bohr is recognized for creating a more accurate model of the atom, particularly through his development of the Bohr model, which was introduced in 1913. This model built upon earlier atomic theories by incorporating elements of quantum theory to explain the behavior of electrons in an atom. Bohr proposed that electrons orbit the nucleus in fixed paths or energy levels, and that they can move between these levels by absorbing or emitting energy in discrete amounts, or quanta. This represented a significant shift from earlier models, which depicted electrons in more classical or undefined paths around the nucleus.

The Bohr model effectively explained the spectral lines of hydrogen, leading to a greater understanding of atomic structure and electron behavior. This marked a critical advancement in atomic theory and laid the groundwork for future developments in quantum mechanics, making Bohr's contributions fundamental to modern physics.
