Most elements have different types of atoms. These variations on an element's atoms are called isotopes and have different numbers of neutrons and thus different atomic masses. It is also possible to artificially create other isotopes of elements that do not exist "naturally," even for the few elements that normally have only one isotope (e.g. gold, arsenic, cobalt, aluminum, phosphorus).

Do atoms of sulfur have a different number of electrons than atoms of any other element?
Every atom of one element has different no. of electrons than any atom of any other element.
what are the 4 points in Dalton's atomic theory?
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.
Do atoms of different elements have similar shapes?
Atoms of any element are usually considered to be spherical in shape.
What do atoms from different elements have?
What distinguishes atoms of one element, from atoms of another element, is the number of protons. For example, any atom that has 6 protons in its nucleus is a carbon atom.
What is an example of an elment?
An element is a pure substance with only one type of atom. Any pure substance - oxygen, carbon, aluminium. It cannot have two different types of atoms, like carbon dioxide, which has carbon atoms and oxygen atoms.
Is it possible for atoms of the same element to have different chemical properties?
Atoms of the same element differ in the number of neutrons in their nuclei. All atoms of a given element have the same number of protons, of course. The number of protons in a nucleus determines which element the atom is. But the number of neutrons can vary, and these different "versions" of a given element are called isotopes of that element. See the related question, which is linked below.
What was Dalton's four proposals or therories?
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
What was Daltons theory based on?
Dalton's theory was based on five principle: 1.An element is fundamentally different from any other element. 2.All atoms of a each element are identical. 3. Atoms from one element can combine with atoms from another element to form compounds. 4. Atoms cannot be created or divided 5. Element are made of small particle called atoms.
What are Dalton points in the atomic theory?

What are five postulates of Dalton's atomic theory?
The five main points of John Dalton's atomic theory are as followed: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.Atoms of one element can combine with atoms of other elements to form 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.
The mass of any two atoms of the same element is always the same?
The masses of any two atoms of the same element are not always the same. Atomic mass (the mass you see on the periodic table) is just a weighted average of all of the weights of all of the different isotopes of an element.
What did John Dalton atomic theory teach?
