The same numbers of protons and of electrons; the difference between isotopes is in the number of neutrons.
The number of protons is identical.
Different Isotopes of the same element will each exhibit the same Chemical Characteristics.
Two different neutral isotopes of the same element have the same number of protons in their nucleus, which determines the element's identity. The isotopes differ in the number of neutrons they have, which leads to variations in atomic mass but not in chemical properties.
They have the same number of protons and electrons.
The number of protons and electrons is the same.
They have the same numbers of electrons and protons.
The proton and electron number are equal for all isotopes of the same specific element.
They have the same number of protons in the nucleus and same number of electrons surrounding the nucleus.
The atomic number is the same for all isotopes.
Two different neutral isotopes of the same element have the same number of protons, which defines the element, and the same number of electrons, making them neutral. However, they differ in the number of neutrons in their nuclei, which results in different atomic masses. This variation in neutron count can lead to differences in stability and radioactive properties among the isotopes.
The number of protons per atom, and the number of electrons per atom.
In a neutral atom, the number of electrons equals the number of protons. Isotopes of the same element also have the same number of electrons and the electronic structure.
