Iodine -131 undergoes radioactive decay to form an isotope with 54 protons and 77 neutrons what type of decay occur in this isotope?
The number 131 on the end shows us the mass of the isotope of iodine
If there are 53 protons, you need to take that away from the mass number to get the number of neutrons
(Remember, electrons have such a small mass, we say that they have no mass at all, just to make it easier)
131 - 53 = 78
So the answer is A

How is nitrogen -15 isotope different from a nitrogen -9 isotope?
Nitrogen-15 would have 8 neutrons, while nitrogen-9 (if it existed) would only have 2.
What is the atom with 8 neutrons and 6 protons?
The atom with 8 neutrons and 6 protons would be carbon-14, a radioactive isotope of carbon.
How man protons does an element have to have to make it radioactive?
An element can be radioactive regardless of its number of protons. Radioactivity depends on the specific isotopes of an element, which can have different numbers of neutrons. Elements with unstable isotopes that undergo radioactive decay typically have too few or too many neutrons compared to the number of protons.
When an isotope is blank it does not undergo radioactive decay?
When an isotope is stable, it does not undergo radioactive decay. Stable isotopes have a balanced number of protons and neutrons in the nucleus, which prevents them from spontaneously changing into another element over time.
What Contains 22 protons and 21 neutrons.?
An element with 22 protons is titanium (Ti), as the number of protons determines the atomic number of an element. With 21 neutrons, this specific isotope of titanium is titanium-43 (Ti-43). This isotope is radioactive and has a half-life of about 22.3 hours.
What element has 6 protons and 8 neutrons?
The element with 6 protons and 8 neutrons is carbon-14, which is a radioactive isotope of carbon.
What does it mean for an isotpe to be radioactive?
An isotope is radioactive if it undergoes spontaneous decay, emitting particles or radiation in the process. This decay results in the transformation of the atomic nucleus into a different element or a different isotope of the same element.
How is nitrogen -15 isotope different from a nitrogen -9 isotope?
Nitrogen-15 would have 8 neutrons, while nitrogen-9 (if it existed) would only have 2.
What radioactive isotope has 68 protons and 31 neutrons?
Element #68 is Erbium. The number of the isotope, of course, is the sum of the protons + neutrons. Checking the Wikipedia article "Isotopes of erbium", it looks as if this isotope doesn't actually exists.
What is the atom with 8 neutrons and 6 protons?
The atom with 8 neutrons and 6 protons would be carbon-14, a radioactive isotope of carbon.
What decay process will occur if an isotope lies above the band of stability on a plot of neutrons vs protons?
If an isotope lies above the band of stability on a plot of neutrons vs protons, it will undergo radioactive decay.
What has 36 protons 43 neutrons and 36 electrons?
This is the radioactive isotope bromine-78.
What isotope has 16 protons and 15 neutrons?
The isotope with 16 protons and 15 neutrons is oxygen-31.
How man protons does an element have to have to make it radioactive?
An element can be radioactive regardless of its number of protons. Radioactivity depends on the specific isotopes of an element, which can have different numbers of neutrons. Elements with unstable isotopes that undergo radioactive decay typically have too few or too many neutrons compared to the number of protons.
What is a plutonium atom?
An radioactive, unstable atom with 94 protons and electrons and a variable number of neutrons - depending on the isotope.
When an isotope is blank it does not undergo radioactive decay?
When an isotope is stable, it does not undergo radioactive decay. Stable isotopes have a balanced number of protons and neutrons in the nucleus, which prevents them from spontaneously changing into another element over time.
