However, let's get our terminology straight: Leucippus didn't "discover" anything, except possibly that his fellow Greeks were willing to listen to any crazy idea you pulled out of your posterior. Leucippus and/or Democritus (his student) were the people who first talked about "atoms", but they had no idea what they were really like or even that they really existed.
What else can I help you with?
What year did leucippus and democritus make their contribution?
Leucippus and Democritus, ancient Greek philosophers, made their contributions to atomic theory around the 5th century BCE. Leucippus is often credited with originating the concept of the atom, while Democritus expanded on these ideas and is known for developing a more comprehensive atomic theory. Their work laid the groundwork for later scientific thought regarding the nature of matter.

How did Moseley discover the atomic theory?
Moseley was the first to clear and scientifically justify in 1913 the atomic number studying X-ray spectra of chemical elements. But Moseley hadn't a personal atomic theory, he was not the discoverer of the atomic theory.
What did leucippus contribute to the atomic model or theory?
he did not develop anything regarding the 'atomic theory' for he was against that theory.

What did Leucippus discover?
Leucippus or Leukippos was a Greek scientist who lived sometime around 450-500 years BCE. He didn't so much "discover" as theorized. He was one of the earliest scientists to come up with the theory of atomism, that everything is made up of particles that cannot be divided up any further. The Greeks called these particles "atoms". His disciple was Democritus.

When was the atomic theory discovered?
Leucippus is a mysterious figure whose exact dates are unknown - some say he never existed - but is still considered the be the founder of the Atomistic theory. Democritus was born 460 B.C. and died 370 B.C. He was a disciple of Leucippus and both men are credited with the atomistic theory.

Did Democritus have a student?
Yes, Democritus had a student named Leucippus. Leucippus is considered to be the co-founder of the atomic theory along with Democritus, and they both proposed that matter is made up of indivisible particles called atoms.
