Isotopes are atoms of an element that contain different number of neutrons in their atomic nucleus. They have the same atomic number, i.e., same number of protons (of course an equal number of electrons), but differ in their atomic mass due to the neutron numbers. For example, the three...
Because each element is distinctive of its atomic number, all atoms of a particular element must have the same number of proton. The atomic number of carbon is 6. Then all kinds of carbon atoms must have 6 protons in their nuclei. So these atoms...
If two atoms have the same number of electrons, then they would have the same electronic configuration and in turn, the same number of valence electrons. This would cause them to have the same valency also. The chemical properties of a element depend on ...
Atoms of the same element that differ in their atomic weight are called isotopes. 具有不同原子量的同一种元素被称为同位素. 来自辞典例句 14. The radium isotopes are absorbed to an appreciable extent through the human and animal gut. 镭的同位素通过人和动物的肠子时有很大部分被吸收. 来自辞典例句 ...
Isotopes are variants of a particular chemical element which differ in neutron number, although all isotopes of a given element have the same number of protons in each atom. The term isotope is formed from the Greek roots isos (ἴσος "equal") and topos (τόπος"place"), mea...
The nuclei must have the same number of protons (an element is characterized by its proton number). Isotopes of the same element have very similar properties because they have the same electron configuration, but differ slightly in their physical properties. An unstable isotope is termed a radio...
Isotopes are atoms that have the same number of protons butdifferent numbers of neutrons. An ion is an atom or molecule with a positive or negative charge. Why do all isotopes have the same properties? Atoms of the same element that differ in their numbers of neutrons are called isotopes. ...
Isotopes of Elements- Isotopes refer to elements with nuclei having the same number of protons, but differing numbers of neutrons, so that the masses of contrasting isotopes differ by one to a few neutrons. To learn more about the Types, Examples, Physic

Isotopes of a chemical element contain the same numbers of protons in their nucleus, but they have different numbers of neutrons. For example, the protium and deuterium isotopes of hydrogen both contain 1 proton, but differ by zero and 1 neutron respectively....
