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.

Which two of Dalton's theory were incorrect?
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.
What is the number that the nuclei of all the atoms of a given element have?
The same number of protons, which is also the atomic number of the element.
What part Dalton atomic theory was later proved to be incorrect?
Today we know that atoms can be destroyed to nuclear reactions but not by chemical reactions.
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.
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.
Do the nuclei of all atoms of a given element always have the same number of neutrons?
No - different isotopes of an element have different numbers of neutrons. All atoms of an element will have the same number of protons.

Is the two atoms have same atomic radius?
Two atoms of same element (for a given isotope) are identical and hence have the same atomic radius.
Is it true that all the atoms of a given element are different from each other?
No. All atoms of the same element have the same number of protons and, when neutral, the same number of electrons. They can, however, differ in the number of neutrons.
What is the number that the nuclei of all the atoms of a given element have?
The same number of protons, which is also the atomic number of the element.
What part Dalton atomic theory was later proved to be incorrect?
Today we know that atoms can be destroyed to nuclear reactions but not by chemical reactions.
Do all the atoms have the same proton number?
In respect to different elements, no they don't, in respect to like atoms of one particular element, yes they do. The electrons are the particles that vary from like atoms of the same element. When the electrons and protons are uneven within an atom, you have a radioactive element.
What does every atom in a particular element have in common?
They all have the same number of neutrons. All atoms of a given element have a specific number of protons. That is what gives an element its elemental identity. But we know that different atoms of a given element can have different numbers of neutrons. These different atoms of the same element are the isotopes of that element. All the atoms of a given isotope of a given element will have the same number of protons and will have the same number of neutrons. all isotopes of an atom have same number of proton but they have different number of neutron so they have same chemical properties and different physical properties. all isotopes of an atom have same number of proton but they have different number of neutron so they have same chemical properties and different physical properties.
Are all atoms of elements the same?
No. Generally definition of an element refer to a group of atoms that have same number of protons and share same chemical properties and called isotopes of an element. Though weight of isotopes can differ representing difference in neutron number.
What is needed for any given element?
An element is defined a "type of atom"; to be more precise, all the atoms in an element have the same number of protons (but not necessarily the same number of neutrons).
