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.
No, according to Dalton's theory, atoms of one element cannot be converted into atoms of another. Atoms are indivisible and cannot be created or destroyed in a chemical reaction. This concept is known as the conservation of matter.
This theory was proposed by the ancient Greek philosopher Democritus. He postulated that all matter is composed of indivisible particles called "atoms" that vary in size and shape to create different substances.
This quote is attributed to British physicist and chemist John Dalton, who proposed the atomic theory of matter in the early 19th century. Dalton's theory stated that all atoms of a given element are identical and have specific characteristics that differentiate them from atoms of other elements.
All atoms of any single element have the same number of protons and electrons.
John Dalton believed that all elements are made of atoms and that atoms are identical if they are of the same element. He is the first one to have combined substances to make new substances through chemical reactions.
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's atomic theory states that elements are composed of indivisible atoms and that all atoms of a given element are identical in mass and properties. Atoms of different elements have different masses and properties.
No, Dalton did not say that all atoms are the same size. Instead, Dalton proposed that all elements are composed of indivisible particles called atoms, and that atoms of different elements have different sizes and properties.
John Dalton postulated that atoms of the same element are exactly alike in his atomic theory developed in the early 19th century.
Because the existence of isotopes was discovered not all atoms of an element are identical.
John Dalton based his conclusions on the measurable characteristic of atomic mass. He proposed that each element consists of unique atoms with specific masses, which could be used to distinguish one element from another. Dalton's atomic theory was grounded in the idea that chemical reactions involve the rearrangement of these distinct atoms, with their mass being a key factor in understanding chemical compounds and reactions.
They are identical.
Atoms are indivisible and indestructible, and all of the atoms of a given element are identical in mass.
In his time were not known the isotopes and Dalton supposed that all atoms of a chemical element are identical.
