There are three isotopes of silicon silicon-28 silicon-29 and silicon-30 what are the same and which are different among the atoms of these isotopes?
they differ only in the number of neutrons.
Does the atomic number change in the three isotopes of hydrogen?
No the atomic number is same for the three isotopes of hydrogen (it is 1). The three isotopes of hydrogen differ by the number of neutrons.
Suppose a newly discovered element has three isotopes that occur in nature Assume that these isotopes occurr in equal amounts in nature What will be the average atomic mass of this element?
You would add 200+203+209 and get 612. Then divide 612 by three. (612/3) to get that the average atomic mass is 204.
What is the atomic number of Ar?
That depends on the isotope, as Argon has three different stable isotopes and many different radioactive isotopes.
What is the average atomic mass of X when X has four isotopes?
There are multiple elements of the Periodic Table which have 4 isotopes. These are further broken down into three which have unstable isotopes, and 6 that do not decay. The 6 that are stable are strontium (Sr), lead (Pb), cerium (Ce), iron (Fe), chromium (Cr) and sulphur (S).

Is silicon radioactice?
Naturally occurring silicon, of which there are three isotopes, is not radioactive, There are a half dozen artificial radioisotopes.
If an element has three isotopes with known masses what information is needed to find the average atomic mass of the element?
The abundance percentage of each isotope
What are three isotopes and isobars of carbon?
isotopes of carbon are atomic no. 6 mass 12 , atomic no.6 mass 13 , atomic no. 6 mass 14

If an element had three isotopes with known masses what other information is needed to find the average atomic mass of the element?
The abundance percentage of each isotope

How do isotopes effect the mass number and the average atomic mass?
When it comes to atomic mass, each proton and each neutron (they're called nucleons when we talk about them in an atomic nucleus) in the nucleus of an atom add about 1 to the atomic mass. Just as a for instance, most hydrogen has just a proton for a nucleus. But some has a neutron attached to the proton, or, in extremely rare instances, two neutrons. In the case of "regular" hydrogen, its atomic mass is about 1 while hydrogen with a neutron stuck to its proton has an atomic mass of about 2. Atomic mass has to take into account some subtleties as regards atoms. Use the links below to sort it out.
Isotopes of an element differ in their?
Isotopes must have the same atomic number, which is the number of protons. The atomic mass, which is the total number of protons and neutrons, varies for the different isotopes. so it should have different mass numbers..
Atomic nomber of carbon?
Carbon is available in three isotopes, C12, C13 and C14. C12 is the most common.
