John Dalton (1766-1844) was a science teacher who also kept detailed records of the weather. He suggested that every chemical element consisted of tiny particles, atoms, which were identical to each other but different from the atoms of other chemical elements. He also gave names and symbols to about 30 chemical elements.
However, he thought that atoms were solid spheres, like metal balls, which could be never destroyed. Also, some substances which Dalton believed were elements are now known to be combinations of elements, or compounds.

∙ 12y agoIn 1803, English chemist-physicist John Dalton starts using symbols to represent the atoms of different elements.
It was the first use of symbols to represent the elements of modern chemistry. He soon had a table of 21 elements arranged by Atomic Mass, which he presented in a scientific paper the following month. Eventually, he had 36 different symbols.

What law states that if two or more compounds are made up of the same two elements the ratio of the masses of the second element is always a ratio of small whole numbers?
In a molecule there will always be integer numbers of a certain atom, and you can never have 3.5 oxygen atoms or 2.493 chlorine atoms in a compound. Atoms are singular units of molecules. Therefore a ratio of integers is always present for all types of atoms in a molecule.
What is a way to show chemical reactions using symbols instead of words?
a formula equation
What do scientists use to convey information on a weather map?
colors and symbols.
What is the number of atoms for potassium iodide?
There is one atom of potassium in a unit of potassium iodide.
How many atoms each elements are in the formula 2C2H6?
Difluoromethane (CF2H2) is a chemical compound composed of 1 carbon atom in the center, and 2 fluorine atoms and 2 hydrogen atoms bonded to it. The posted formula represents one molecule of this compound, and it's composed of the 5 atoms you see in the formula. Use the link below to see a diagram and learn more.
Why did john Dalton use the Greek word for invisible to describe atoms?
to describe the answer beter
Who is the scientist who first proposed the use of chemical symbols?
No single scientist has devised the symbols of the elements. An organization called the International Union of Pure and Applied Chemistry (IUPAC) has determined the symbols of the elements on the Periodic Table.
Who discovered the atomic theory?
john dalton developed the atomic theory , which he published in 1803
Did john Dalton use electrolysis directly?
No
What symbols do we use to indicate that atoms have become ions?
we use + and -
What did William Crookes use to test John Dalton's theory?
A tube!
Why is John Dalton's atomic theory still mentioned in science?
Scientists use Dalton's atomic theory even though parts of it have been proven wrong as the basis of other discoveries. His theory about atomic elements being the same was wrong but has been used for a long time even to the discovery of isotopes.
'atoms can neither be created nor be destroyed'-who published this principles?
Good Question. this principle was given by John Dalton. He might be the first one to use this phrase. thank you. sorry if am mistake. All the best.
Who is credited with the first atomic theory based on expiramental evidence?
scientific method used in the development of atomic theory
Why do scientists use symbols to represent atoms?
Symbols are universally understood across many languages. Also, using symbols rather than full names helps scientists to avoid the repetition of writing the long names of elements and atoms again and again.
How would you use testimonial in a sentence?
The statue of John Dalton in Manchester, England, is a testimonial to his scientific contributions.
