...electrons.
Isotopes contain the same number of protons (hence, the same number of electrons) and electrons are what determine reactivity. 2nd answer : The isotopes have the same chemical properties because the electronic configuration of an element is same there fore isotopes posses the same chemical properties .
Isotopes have the same number of protons. They have different numbers of neutrons.
Isotopes of an element have the same number of protons. equal to the atomic number of that particular element in the periodic table.
Masses.
protons & atomic number
Protons and Electrons but NOT neutrons
Neutrons.
All of the isotopes of an element have the same chemical properties because they all have the same number of protons and the same number of electrons in their valence shells.
Isotopes of the same element differ in the number of neutrons. Isotopes have different physical properties but similar chemical properties.
Isotopes are atoms of the same element with different numbers of neutrons. They do have very similar chemical properties. In fact for most purposes we can consider them identical.
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.
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.
Chemical properties of a element is governed by ELECTRONIC CONFIGURATION of that element. As isotopes of same element have identical electronic configurations, their chemical properties are same.
Isotopes contribute to the atomic weight of a chemical element.
chemical properties
All of the isotopes of an element have the same chemical properties because they all have the same number of protons and the same number of electrons in their valence shells.
The chemical properties of an element depend on its electron configuration, which is in turn determined by the number of protons. Isotopes of an element differ in the number of neutrons, which, being neutral, have not influence on chemical properties.
The number of electrons in isotopes is identical.
Chemical properties are determined by the electron configuration of an atom, not by its mass. These do not differ in all isotopes of one element, because isotopes have the same number of PROTONS thus the same electron configuration. Only the mass of different isotopes of one element is different by the different number of NEUTRONS.
The identity of a chemical element is given by the number of protons.
The differences in chemical properties are not significant (excepting protium and deuterium); the physical properties are different.
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.
Isotopes of the same element differ in the number of neutrons. Isotopes have different physical properties but similar chemical properties.
All the isotopes of a chemical element are identical; some differences exist for light elements (ex. H or D).
