An Isotope has the same number of Protons (and thus electrons in its electrically neutral state) but a different number of Neutrons.
Ergo, an element is defined by the number of Protons in its nucleus.
Protons and thus to keep the atom electrically neutral, electrons too. Different isotopes would have a different number of neutrons.
valence electrons.
Atoms of the same element are alike and always have the same number of protons in their nuclei.
No, atoms of the same element have the same number of protons. Atoms of the same element with different numbers of neutrons are called isotopes.
Isotopes are atoms of the same element, having the same number of protons but different number of neutrons.
IsotopesThe number of protons in the nucleus of an atom determines the element. The number of neutrons can vary. If two atoms of the same element have a different number of neutrons in their nuclei, they are isotopes of that element.
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.
All atoms with the same number of protons are atoms of the same element. The number of protons is the atomic number of the element.
Yes, all atoms of the same element have the same number of neutrons.
Element refers to atoms that have the same number of Protons.
Atoms of the same Element have this.
Isotopes are atoms of the same element, having the same number of protons but different number of neutrons.
All atoms of the same element are not identical. The atoms of same element with different number of neutrons are called as isotopes. Although, the number of protons and electrons are same in every atom.
Atoms of the same element are alike and always have the same number of protons in their nuclei.
Atoms with the same atomic number are all atoms of the same element. However, if the atoms have different molecular weights, they are isotopes of the same element.
No, atoms of the same element have the same number of protons. Atoms of the same element with different numbers of neutrons are called isotopes.
The number of protons is identical in all atoms of an element.
Yes. If two atoms have the same number of protons then by definition they are the same element.
All atoms of the same element have the same number of protons, which is its atomic number. A neutral atom will have the same number of electrons as protons.
