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?
The average atomic mass of the element would be the average of the atomic masses of the three isotopes. Since they occur in equal amounts, the average atomic mass would be the sum of the atomic masses of the three isotopes divided by 3. This average atomic mass is a weighted average, taking into account the relative abundance of each isotope.
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?
The atoms of all three isotopes have the same number of protons (14) and electrons, but differ in the number of neutrons: silicon-28 has 14 neutrons, silicon-29 has 15 neutrons, and silicon-30 has 16 neutrons. This variation in neutron number gives each isotope a different atomic mass.
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 that a newly discovered element called centium has three isotopes that occur in nature. These are centium- 200 cenitum- 203 and centium- 209. Assume that the isotopes occur in equal amounts in?
If centium has three isotopes—centium-200, centium-203, and centium-209—occurring in equal amounts, the average atomic mass can be calculated by averaging the mass numbers of the isotopes. Since they are present in equal proportions, the average atomic mass would be (200 + 203 + 209) / 3 = 204. The average atomic mass of centium would therefore be approximately 204 atomic mass units (amu).
Does silicon have any isotopes?
Yes: Naturally occurring silicon contains isotopes with mass numbers 28, 29, and 30 in order of decreasing abundance. As with almost any element, many artificial, radioactive isotopes are also known.

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 unknown natural abundance percentages what other information is needed to find the average atomic mass of the element?
You would need the masses of each isotope and the abundance percentages of at least two of the isotopes. The average atomic mass is calculated by multiplying the mass of each isotope by its abundance, summing these values for all isotopes, and then dividing by 100.
If an element has three isotopes with known natural abundance percentages what kind of information is needed to find the average atomic mass of the element?
To find the average atomic mass of the element, you would need the mass of each isotope and their corresponding natural abundance percentages. Multiply the mass of each isotope by its respective abundance percentage, then sum these values for all isotopes to determine the average atomic mass of the element.
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
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 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
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).
