They have the same number of protons and electrons.
St. X too? Yeah I don't know either man...
All isotopes of carbon have 6 protons and, in a neutral atom, 6 electrons.
- All the isotopes of uranium are unstable
- All the isotopes of uranium are radioactive
- All the isotopes of uranium have 92 protons and 92 electrons
What they have in common is that they all have 11 protons in the nucleus.How they differ is that they have different numbers of neutrons in the nucleus.
Same number of protons and electrons.
The nuclei of all plutonium isotopes contain the same number of protons.
All isotopes of an element have the same number of protons in the atomic nucleus, which is its atomic number on the periodic table. All isotopes of an element contain different numbers of neutrons in their atomic nuclei, which causes the isotopes of an element to vary in mass number (protons + neutrons).
Number of protons in the nuclei of their atoms.
Na -23 is the most abundant isotope, because the atomic massfor Na on the periodical table of elements is 22.99 and 22.99 isclosest to 23.
The atoms that are radioactive are those with unstable nuclei. There is no easy way to tell which is which, so the isotope has to be looked up. All elements have at least some radioactive isotopes. There are 36 elements for which all radioactive isotopes are synthetic or fission products, so for practical purposes, there are no radioactive isotopes of them in nature, except where introduced by human activity. They include most of the common elements we find in nature, but not all. There are 44 elements that are found as stable isotopes, but at least traces of radioactive isotopes are found in nature. Among these are hydrogen, carbon, sodium, silicon, chlorine, and potassium, all of which are necessary for life. Radioactive potassium, in particular, is present as 0.012% of all potassium. For another group of elements, including technetium, promethium, and all with atomic numbers of 83 (bismuth) or more, there is no isotope that is stable.
What they have in common is that they all have 11 protons in the nucleus.How they differ is that they have different numbers of neutrons in the nucleus.
All carbon isotopes have the same number of neutrons.
Sodium does not have naturally occurring radioactive isotopes - as it has only 1 naturally occurring isotope, which has 11 protons and 12 neutrons, and is not radioactive. However, the 18 other known types of sodium isotopes are all radioactive, and sodium-22 (the most stable radioactive sodium isotope) has a half life of 2.6 years.
All carbon isotopes have the same number of neutrons.
The number of protons (the same as atomic number) is specific for all isotopes.
The nuclei of all plutonium isotopes contain the same number of protons.
Eleven. This because sodium has an atomic number (also the number of protons) of 11 on the periodic table. All the elements listed on the table are the most common (or only) isotopes of those elements.
Not all of the transition elements are radioactive. Many of them are, and some of them have common radioactive isotopes, but some of them have no naturally occurring radioactive isotopes. Please note that all elements have synthetic radioactive isotopes, at least.
The reason behind sodium's atomic mass being 22.990 is quite simple. They use the average of all isotopes, which equals out to 22.990.
The proton and electron number are equal for all isotopes of the same specific element.
The atomic mass of chlorine is a weighted average of the masses of all its naturally occurring isotopes, taking into account their abundance. Chlorine has two main isotopes, chlorine-35 (with an atomic mass of approximately 34.97) and chlorine-37 (with an atomic mass of approximately 36.97). The 0.5 difference in the atomic mass comes from the relative abundance of these isotopes in nature.
All isotopes of an element have the same number of protons in the atomic nucleus, which is its atomic number on the periodic table. All isotopes of an element contain different numbers of neutrons in their atomic nuclei, which causes the isotopes of an element to vary in mass number (protons + neutrons).
