John Dalton it was referred to the atoms of the same element.
Dalton's atomic theory proposed that all atoms of a particular element are identical, which we now know is not entirely true. Isotopes are atoms of the same element with different numbers of neutrons, leading to variations in atomic mass. This discovery challenged Dalton's rule of identical atoms for a given element.
Dalton's Atomic Theory 1) All matter is made of atoms. Atoms are indivisible and indestructible. 2) All atoms of a given element are identical in mass and properties 3) Compounds are formed by a combination of two or more different kinds of atoms. 4) A chemical reaction is a rearrangement of atoms.
Dalton discovered that the atoms that combine to form compounds are distinguished from one another by their atomic weights. He also learned that all atoms of a given element are identical.
All atoms have atomic numbers which are the same and the atoms have the same number of electrons.
A substance in which all atoms are identical is called an element.
No, Dalton's atomic theory did not include the idea that all atoms of all elements are the same size. Instead, he proposed that atoms of different elements have different sizes and weights.
It was proposed by John Dalton in his atomic theory.
According to John Dalton, all the atoms of a single element will have the same mass. This is the basis for the modern atomic theory.
John Dalton
He concluded that all atoms of an element have same mass and identical chemical and physical properties.
Dalton. Dalton's atomic theory stated that atoms are indivisible and indestructible and unchangeable.
In the 1800s John Dalton did some experiments and these are some of his magnificent work: * all elements are composed of atoms. atoms can not be divided or destroyed * atoms of the same element are alike * .atoms of different elements are not alike * the atoms of two or more elements can join together to form compounds
It was then changed to "All atoms of the same element contain the same number of protons and electrons, but atoms of a given element may have different numbers of neutrons." after James Chadwick discovered that the nuclei of most atoms contain neutrons as well as protons.
1. Atoms are impenetrable and aren't destructible. All material is made up of very, very small atoms. 2. All atoms of an element have the same mass and the same properties. 3. Mixtures are made by a fusion of 2+ unlike classifications of atoms. 4. A chemical reaction is a displacement of atoms.
John Dalton proposed the atom theory in the early 19th century. He suggested that all matter is made up of tiny, indivisible particles called atoms, and that all atoms of a specific element are identical in size, mass, and properties.

Both Dalton and Democritus proposed that matter is made up of indivisible particles called atoms that are different in size and shape. They also believed that atoms are in constant motion and can combine to form different substances.
