Do all atoms of sodium isotopes have the same number of neutrons?
yes BECAUSE THEY SHOW THAT IN THE PERIODIC TABle SEVERAL THINGS OCCUR THEREFORE I AGREE WITH THIS STATEMENT
Why is the atomis mass of sodium 22.99?
The atomic mass of sodium is 22.99 because it is an average mass of all the naturally occurring isotopes of sodium, taking into account their abundance in nature. Isotopes are atoms of the same element with different numbers of neutrons, which affects the overall atomic mass.
What is a similarity and a difference between isotopes of an element?
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).
What is the most common isotope of neon?
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.
What do the nuclei of different plutonium isotopes have in common?
The nuclei of different plutonium isotopes all contain 94 protons, which define the element as plutonium. The isotopes differ in the number of neutrons they contain, resulting in different atomic masses for each isotope.
What do all sodium isotopes have in common and how do they differ?
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.
Is sodium an isotope?
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.
What do all carbon isotopes have in common?
All carbon isotopes have the same number of neutrons.
Why is the atomic mass of sodium 22.990 and not 22?
The atomic mass of sodium is 22.990 because it is an average mass of all naturally occurring isotopes of sodium, taking into account their relative abundances. Sodium has multiple isotopes with slightly different masses, which contributes to the atomic mass being a non-integer value.
Do all atoms of sodium isotopes have the same number of neutrons?
yes BECAUSE THEY SHOW THAT IN THE PERIODIC TABle SEVERAL THINGS OCCUR THEREFORE I AGREE WITH THIS STATEMENT
What do Carbon isotopes have in common?
All carbon isotopes have the same number of neutrons.
Why is the atomis mass of sodium 22.99?
The atomic mass of sodium is 22.99 because it is an average mass of all the naturally occurring isotopes of sodium, taking into account their abundance in nature. Isotopes are atoms of the same element with different numbers of neutrons, which affects the overall atomic mass.
What number do all the isotopes of carbon has in common and what does that number represent?
The number of protons (the same as atomic number) is specific for all isotopes.
How many protons are in sodiums most common isotope?
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.
Are all transition elements are radioactive?
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.
What do two different neutral Isotopes have the same elements in common?
The proton and electron number are equal for all isotopes of the same specific element.
Where does the 0.5 in chlorine's atomic mass come from?
There are different isotopes of the element. Isotopes are atoms of an element that have different amounts of protons, so the isotopes with more protons weigh more because there is more mass in the atom. Some isotopes are more common than others, and the atomic mass is a weighted AVERAGE of all the isotopes of that element. On most elements there is a large difference between the most common and lesser common isotopes, but chlorine has 2 isotopes that are very close. So the average ends up between the two numbers. The actual weight of 1 atom will never be something.5 because protons and neutrons weigh 1amu and electrons weigh 0. But in most cases the sample of a chemical you use will be a mixture of the isotopes, so the .5 weight will be correct.
