No. Most elements have several isotopes, which differ in the number of neutrons, which in turn affects Atomic Mass.
Dalton believed that there was a different atom for each element that there was, and that these atoms made up the elements that were in existence. He did not say exactly how these atoms were different, just that they were different. Dalton also believed that all of the atoms for a given element were exactly alike in every way.
* All elements are made of tiny indivisible particles called atoms. * All atoms of a given element are alike but the atoms of one element differ from the atoms of every other element. * Atoms are not created, destroyed or converted into other kinds of atoms during chemical reactions. They are simply rearranged into new compounds. * Compounds result from the chemical combination of a specific ratio of atoms of different elements 10A who is asking this question
daltons atomic postulations stated that: * Elements are made of tiny particles called atoms. * All atoms of a given element are identical. * The atoms of a given element are different from those of any other element; the atoms of different elements can be distinguished from one another by their respective relative weights. * Atoms of one element can combine with atoms of other elements to form chemical compounds; a given compound always has the same relative numbers of types of atoms. * Atoms cannot be created, divided into smaller particles, nor destroyed in the chemical process; a chemical reaction simply changes the way atoms are grouped together.
These affirmations are not valid today:· All atoms of a given element are identical.· A given compound always has the same relative numbers of types of atoms.
Atoms of a given element always have the same number of protons in their nucleus. Neutrons can vary (in different isotopes) and electrons can vary (in different ions) but protons are always the same for a given element. If the number of protons is changed, then you no longer have the same element.
No. All atoms of a given element are alike in the number of protons, which is the atomic number of an element. However, the number of neutrons in the nucleus can vary. Atoms of elements with the same number of protons but different numbers of neutrons are called isotopes. All atoms of a given element in their ground state have the same number of electrons as they do protons, but if they form ions, the number of electrons will increase or decrease, depending on the element, but the number of protons remains the same.

True statements: All neutrons are alike, all electrons are alike, all protons are alike (All atoms of a given isotope is only alike). False statement: All atoms are alike All atoms are not alike as they may vary in the number of protons / electrons / neutrons.
Elements are made of tiny particles called atomsAll atoms of a given element are identical (Proven wrong)The atoms of a given element are different from any other element (Not completely true)Atoms of one element can combine with atoms of another element to form chemical compounds

(These are loose interpretations of his original five statements)

Isotopes.
Theory forming the basis of accepted modern atomic theory, according to which matter is made of particles called atoms, reactions must take place between atoms or groups of atoms, and atoms of the same element are all alike but differ from atoms of another element.
Today we know that atoms can be destroyed to nuclear reactions but not by chemical reactions.
