Isotopes

When an atom is of the same atomic number, atomic mass, etc. to the one on the periodic table (Lets use Boron for example) Then B is the regular atom. But if you change the number of nuetrons (from 6-to-7 or whatever number) ; because the number of protons never changes; you will get a different atomic mass, so an isotope is the atom with a different atomic mass. You write an isotope atom with the elements symbol and to the left of it you script (In the top left corner really small like an exponent) the new atomic mass. So in this case B would now be 12B. (except scripted, but I sadfully forgot how to do that on a computer....)

radioactive isotopes are isotopes with irregular nuclear composition, it emits energy due to decay of atomic nucleus.

Doofus.

Atomic # - 128

Atomic mass - 320.04 amu

There isn't another name for isotopes. What it means is Any two or more forms of a chemical element, having the same number of protons in the nucleus, or the same atomic number, but having different numbers of neutrons in the nucleus, or different atomic weights. There are 275 isotopes of the 81 stable elements, in addition to over 800 radioactive isotopic forms.

A stable isotopes won't decay. But for radioisotopes, it's practically impossible, at least as far as our current knowledge goes. but we do have technology to slow or speed up the process of decay. it happen in the every nuclear reactors. usually through the manipulation of the freed neutrons.

Argon-40 is the most common isotope of argon, making up about 99.6% of natural argon. It is formed by the radioactive decay of potassium-40 in rocks.

Some isotopes are stable, others are unstable.

Yes, alcohol can have isotopes. Isotopes are variations of elements that have the same number of protons but a different number of neutrons. Different isotopes of alcohol may have slightly different chemical properties but have the same basic structure.

The isotope symbol for Barium-137 is Ba-137.

Neon-22 has 10 protons, so it also has 10 electrons to balance the charge. To find the number of neutrons, subtract the number of protons (10) from the isotope's mass number (22). Therefore, Neon-22 has 12 neutrons.

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.

Nitrogen's atomic number is 7. That means that it has 7 positively charged protons in the nucleus. To be neutral, nitrogen must then also have 7 negatively charged electrons in its electron cloud.

Technetium has no stable isotopes but at least 30 artificial ones have been identified.

The most common plutonium isotope is plutonium 239.

The lightest element without a stable isotope is Technetium (atomic number 43). All of its isotopes are radioactive, with none occurring naturally on Earth.

Isotopes have the same number of protons (which determine the element) but may have a different number of neutrons. They do not have extra electrons or protons; the number of electrons in an isotope is the same as the number of protons, ensuring the overall charge is balanced.

No, radioactive isotopes are not inherently cursed. They can be used for beneficial purposes in fields such as medicine, industry, and energy production. However, if not handled properly, they can pose health and environmental risks.

Iodine-125 (I-125) is commonly used as a therapeutic seed implant for prostate cancer. These small radioactive seeds are implanted directly into the prostate gland to deliver targeted radiation therapy to the cancerous cells while minimizing damage to surrounding healthy tissue.

Bromine is the member of group 7 that exists as two stable isotopes: bromine-79 and bromine-81. These isotopes have slightly different atomic masses due to variations in the number of neutrons.

The cost of 1 gram of isotopic copper can vary based on the isotopic composition and market conditions. Generally, isotopic copper can be much more expensive than regular copper due to the specialized production processes involved in isolating specific isotopes. Prices can range from hundreds to thousands of dollars per gram.

It depends on the half life of the isotope. If the half life is, for example, 10 minutes, then 1/8 of the parent isotope will remain (30/10 = 3; 1/2^3 = 1/8).

Essentially, to work out the remaining fraction, you firstly divide the period of time by the half life (the answer in this case is X), and then do 1/2 to the power of x.

Carbon-12 isotope is used to define the atomic mass unit, which is equal to 1/12th of the mass of a carbon-12 atom.

It isn't, as such. Isotopes of the same element have different numbers of neutrons, and neutrons have a mas of one atomic mass unit (amu). So isotopes have different atomic masses, but being told the number of neutrons any isotope has, will not enable you to say what element or atomic mass it had, unless you remembered the details for every single isotope. Even then different elements can have the same number of neutrons. Isotopes do get named after their atomic mass however - uranaium 235 has an atomic mass of 235, for instance.
