As an element occurs as a mixture of naturally occurring isotopes what is the atomic mass of the element based upon?
The atomic mass of an element is based upon the weighted average of the atomic masses of the naturally occurring isotopes of that element. We need to know what isotopes of a given element occur in nature, and what percentage of the natural abundance of an element each of those naturally occurring isotopes represents. What that means might be more easily seen if we just run through some examples. So let's run through some.We have an element with 3 naturally occurring isotopes. They occur equally. That is, each one represents a third of the natural atoms, or 33 1/3 % of them. If the atomic masses of our isotopes are 17, 18 and 19, and all occur equally, then it's 17 + 18 + 19 (which equals 54) divided by 3 which is 54 divided by 3 which is 18. Our atomic mass for the element cited is 18, and that represents all the natural isotopes and the percentage in which they occur. Pretty easy.We have an element with 4 naturally occurring isotopes. Here are their atomic masses and percent abundance: a = 46 (25%), b = 47 (50%), c = 48 (15%), and d = 49 (10%). There is a (fairly) simple process one can use to find the weighted average. Multiply the percent natural abundance times the atomic mass of each one and add them all together. Not to difficult, is it? Roll up your sleeves and let's have at it.46 x 25% = 11.547 x 50% = 23.548 x 15% = 7.249 x 10% = 4.911.5 + 23.5 + 7.2 + 4.9 = 47.1 atomic mass unitsSo now we have our atomic mass for our mystery element in example two. We calculated it by determining a weighted average of the naturally occurring isotopes. And that's very important information to take to the lab where we'll be measuring (weighing) some of this stuff.
Which isotopes combined during the sun's nuclear reactions and the element created?
In the sun's nuclear reactions, hydrogen isotopes combine to form helium-4. Specifically, two hydrogen-1 isotopes combine through a process called nuclear fusion to create a helium-4 atom, releasing energy in the form of gamma rays and neutrinos.
How do radioisotopes of an element differ from other isotopes?
Radioisotopes are unstable isotopes that undergo radioactive decay, emitting particles and/or energy in the process. This distinguishes them from stable isotopes that do not undergo radioactive decay. Radioisotopes are often used in medicine, industry, and research for various applications due to their unique properties related to their decay process.
What is isotope and radio isotope?
Isotopes are atoms of the same element with the same number of protons but different number of neutrons. Radioisotopes are isotopes that are unstable and undergo radioactive decay, emitting radiation in the process. They are commonly used in medicine, industry, and research.
What does it means if an isotope is fissile?
If an isotope is fissile, it means that it can undergo nuclear fission reactions when bombarded by neutrons. This process releases a large amount of energy and more neutrons that can sustain a chain reaction. Fissile isotopes are commonly used in nuclear reactors and weapons.
Why does radioactivity occur in some elements?
It occurs due to the instability of the element. It is a spontaneous process. Radioactive atoms are known as isotopes.

WHAT isotopes are used in this process?
U didn't mention which process
What is the decay element of uranium?
It is not yet discovered since all of the uranium isotopes are having half life for several millions of years. We would be able to find it after atleast 700 millions of years.
What does it means if an isotope is fissile?
If an isotope is fissile, it means that it can undergo nuclear fission reactions when bombarded by neutrons. This process releases a large amount of energy and more neutrons that can sustain a chain reaction. Fissile isotopes are commonly used in nuclear reactors and weapons.
What did radioactivity reveal about the atom?
That some atoms are not stable, and that they release mass from their nuclei to become other isotopes or elements. Until the process of fusion was understood, nuclear decay was the only known way for one element to become another element.
What element is formed when the hydrogen bomb explodes?
When a hydrogen bomb explodes, the primary element formed is helium. This occurs through the process of nuclear fusion, where hydrogen isotopes combine to form helium atoms, releasing a large amount of energy in the process.
Are most isotopes stable?
No, most isotopes are not stable. Many isotopes are radioactive and decay over time, releasing radiation in the process. Only a few isotopes are stable and do not undergo radioactive decay.
When an isotopes atomic number changes what does the decay create?
When an isotope's atomic number changes due to decay, it creates a new element. This process occurs through the emission of particles or radiation, which can result in the conversion of one element to another.
