Isotopes of the same element have the same atomic size because atomic size is determined by the number of protons and this number is always constant for an element. The mass number of isotopes may however vary.
Isotopes are basically elements with the same number of protons and electrons but differing number of neutrons. This makes them similar in terms of chemical properties (as electrons are involved in determining chemical properties), but with different physical properties.
Isotope is the element which has the same atomic number but different mass number. This means that same number of protons in the core, but different number of neutrons. Hence both would have same number of electrons. So both have same chemical properties. But because of difference in the number of neutrons both would have different physical properties.
Their atoms contain the same numbers of protons (and electrons, if the atoms are neutral) and have almost exactly the same chemical reactivity.
The difference is in the number of neutrons they contain, thus changing the atomic weight.
All isotopes of a given element contain the same amount of protons and electrons.
they have the same number of protons and different numbers of neutrons.
neutral isotopes also have the same number of electrons as protons.
ionized isotopes do not.
Generally (excepting isotopes with low atomic number) the difference is minimal, not significative.
All the isotopes of a chemical element have the same number of protons and electrons; but the number of neutrons is different.
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).
Chemical reactions involve electrons - not protons or neutrons. All isotopes of the same element have an identical number of electrons (just the number of neutrons differs) and hence the chemical properties are identical/very similar.
The atomic weight of calcium is 40,078.The atomic weight of titanium is 47,867.----Dalton principles not accepted today:Atoms of a given element are identical in size, mass, and other properties; atoms of different elements differ in size, mass, and other properties. But: Isotopes of a chemical element are not identical.Atoms of different elements combine in simple whole-number ratios to form chemical compounds.But: From many time nonstoichiometric componds are known.3. Atoms cannot be subdivided, created, or destroyed.But: This is valid only for chemical methods.
The atomic size for the element is very large.
Element 19, potassium: atomic radius = 227 pm. Element 35, bromine: atomic radius = 120 pm.

The chemical properties of an element are determined by the number and configuration of its electrons, which depends on the size of the charge of the atom's nucleus. The charge is determined by the number of protons. Isotopes of a given element differ only in the number of neutrons, which do not have a charge and thus do not affect the electron configuration.

An Isotope of an element is an atom that has the same number of protons, (number of protons is the defining feature of an element) but different number of neutrons.Because The mass number is the sum of protons and neutrons, different isotopes have different mass numbers.
The atomic number of an element determines the number of protons that are present in that element. The atomic size refers to the distance that the outermost valence electrons are from the nucleus.
Hydrogen has the smallest atomic size of any element.
May be Cesium(Cs)
Hydrogen.
Atomic Mass is the number of protons in an atom plus the number of neutrons in the same atom.
