John Dalton it was referred to the atoms of the same 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.
Like all atoms they are tiny. Compared with other atoms, iron atoms are of medium size.
No, all plates are not the same size
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.
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.
Dalton visualizes "atoms" as being indestructible and that all matter were made of atoms
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.
Dalton's theory said that "atoms of the same element are the same as each other in terms of mass, color, and size." We know that this cannot be true because isotopes of the same element, oxygen for example O-16 and O-17, have different mass numbers (atomic mass). Dalton's theory said that "atoms of the same element are the same as each other in terms of mass, color, and size." We know that this cannot be true because isotopes of the same element, oxygen for example O-16 and O-17, have different mass numbers (atomic mass).
He said that atoms cannot be destroyed nor created, and atoms are indivisible but now the scientists can break atoms into parts so now they are no more indivisible. So the last law of Dalton's Atomic Theory have been modified.
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.
Not necessarily, because most elements have isotopes, which have slightly different weights. However, atoms of a particular element always have the same number of protons, equal to the atomic number of the element.
