false they have the same number of protons, but varying numbers of neutrons
False: The number of protons per nucleus is an essential characteristic of each element.
The most important is the fact that the number of neutrons is different.
That is true. They are known as isotopes.
The isotopes of an element are alike in that they have the same number of protons, electrons, and the same chemical properties. The isotopes are different in that they have different numbers of neutrons and thus different atomic masses.
An element is defined by the number of protons, so this cannot vary. Isotopes of a particular element are different in the number of neutrons within the atoms. These isotopes are said to be comparatively "lighter" or "heavier" than other isotopes based on the total of protons and neutrons (atomic mass).
They have the same number of protons and different number of neutrons.
...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 .
No. The essence of an isotope is that all isotopes have the same number of protons in the nucleus, and thus the same number of electrons. What varies is the number of neutrons in the nucleus.
The isotopes of an element are alike in that they have the same number of protons, electrons, and the same chemical properties. The isotopes are different in that they have different numbers of neutrons and thus different atomic masses.
Isotopes have the same number of protons and electrons; the number of neutrons is different.
Isotopes have the same number of protons an electrons; the number of neutrons is different.
NO. Isotopes are forms of an element that have the same numbers of protons and electrons, but differing numbers of neutrons. For example Helium-3 has two protons, two electrons, and one neutron and Helium-4 has two protons, two electrons, and two neutrons.A form of an element that has a different number of electrons than the number of protons is an "ion".
Isotopes have the same amount of protons but a different amount of neutrons.
All the isotopes of a chemical element have the same number of protons and electrons but the number of neutrons is different.
Isotopes of the same element have the same number of protons and electrons, but varied numbers of neutrons.
Isotopes are different forms of the same element which have different numbers of neutrons in their atomic nuclei. A given element is identified by the number of protons in its nucleus; that's its atomic number. Two different isotopes of the same element have the same number of protons, but each has a different number of neutrons in its nucleus. Different isotopes of the same element are chemically the same.
The isotopes of the same element have an identical number of protons and electrons; the number of neutrons is different.
Isotopes have a different number of neutrons but the number of protons and electrons is the same.
The atoms of a chemical element can exist in different types. These are called isotopes. They have the same number of protons (and electrons), but different numbers of neutrons. Different isotopes of the same element have different masses.
The number of protons and electrons is the same.
