John Dalton FRS (/ ˈdɔːltən /; 5 or 6 September 1766 – 27 July 1844) was an English chemist, physicist, and meteorologist whose work laid the foundations of modern atomic theory and stoichiometric chemistry.
John Dalton, English meteorologist and chemist, a pioneer in the development of modern atomic theory. His theory was notable for, among other things, positing that each element had its own kind of atom and that atoms of various elements vary in size and mass. Learn more about Dalton in this article.
Although a schoolteacher, a meteorologist, and an expert on color blindness, John Dalton is best known for his pioneering theory of atomism. He also developed methods to calculate atomic weights and structures and formulated the law of partial pressures.
In 1804, English chemist and physicist John Dalton introduced an atomic model to understand the composition of matter. According to this theory, all compounds are made of indivisible particles, known as atoms, that combine in well-defined ratios.
John Dalton developed the modern atomic theory that explained matter as being made of tiny atoms. Dalton's Atomic Theory includes ideas like atoms are small and indestructible and obey specific laws. Before Dalton, people like Democritus and Aristotle had different beliefs about the nature of atoms.
I'm having difficulty understanding when to use students' vs students. I know you use students' when you're talking about more than one student. For example: "The students' homeworks were marked".

1 "All the students" and "all of the students" mean the same thing regardless of context. When you qualify all three with "in the school", they become interchangeable.

For a list, use "Student Names" or "Students' Names". Remember that nouns can function as adjectives in English. If you want to show group possession, you put an apostrophe after the "s". The second way is considered a fancier way of writing it since most native English speakers rarely use the plural-possessive apostrophe even though it's well-accepted. For a table-column heading, use "Student ...
But grammatically, there is a difference. Nurdug's "one of the students' name" = " {one of the students}' name". Your "one of the students' names" = "one of {the students' names} ". In informal conversation, we might conceivably use nurdug's formulation, because the context would make it clear what we were talking about.
"There were students on the bus" ~ "There were no students on the bus". The negator "no" (a negative determiner) is of course required with the latter, but with positive plural NPs, a determiner is optional. So you can say "there were twenty students on the bus" (quantified), or "there were students on the bus" (unquantified). You can also say "There was a student on the bus" and the negative ...

Dalton is best known for his formulation of the atomic theory, which clarified our understanding of how atoms combine to form compounds, and how atoms may form new combinations during chemical reactions.
Dalton's most significant contribution to science was his development of modern atomic theory. In 1803, he proposed that all matter is composed of small, indivisible particles called atoms.
