John Dalton came first; he proposed his atomic theory in the early 1800s, specifically around 1803. Niels Bohr, on the other hand, developed his model of the atom in 1913, which introduced the idea of quantized energy levels for electrons. Thus, Dalton's work predates Bohr's by over a century.
What else can I help you with?
Was niels bohr the first to come up with the atom?
No. Ancient Greek philosophers postulated the existence of atoms.In 1803, John Dalton proposed an atom to explain chemical reactions that had been observed by scientists since the 1800's.
Who drew the atom as a nucleus surrounded by electrons?
Dalton 'drew' the first atom, however, this was essentially a circle with a letter in it. The popular version of the atom, as seen today, was theorized by Rutherford.
Whose atomic model first determined that electrons were in energy levels?
Neils Bohr
Planetary model of the atom where electrons orbit around nucleus?
Dalton's

When did Dalton come up with the atom?
Dalton didn't discover the atom. Democritus did. Dalton, however was the first to use the word atom. which comes from the GGreek word atomos, meaning "cannot be split"

Neils Bohr
Who are the scientist that develop of the concept of the atom?
Some of the key scientists who played a major role in developing the concept of the atom include John Dalton, J.J. Thomson, Ernest Rutherford, and Niels Bohr. Dalton proposed the atomic theory, Thomson discovered the electron, Rutherford conducted the famous gold foil experiment leading to the nuclear model of the atom, and Bohr developed the planetary model of the atom.
Who are the scientist of atoms?
Democrates first thought of atoms, but Aristotle disapproved his hypothesis. This idea was discarded. John Dalton, an English teacher, looked back on Democrates's hypothesis and created the Atomic theory. JJ Thomson corrected the atomic theory because it stated that atoms were indivisible and this, of course, is not true (protons, neutrons, and electrons).
