What are the properties of radioactive decay?
Radioactive decay has the following properties: 1. No element can completely decay. 2. The number of atoms decaying in a particular period is proportional to the number of atoms present in the beginning of that period. 3. Estimate of radioactive decay can be made by half life and decay constant of a radioactive element.
Why are most atoms in period 7 synthetic and radioactive?
They are synthetic because they were made, not found in nature. Most of them are radioactive because they are so unstable.
Is it true that The length of time required for half of the radioactive atoms in a sample to decay is its period?
It's period of half of decay.
Is a period of an element the amount of time it takes for half of a radioactive isotope to decay?
False- the period is the horizontal row the element is in
What period is the element neodymium?
period 6
The period of elements that are all radioactive?
All elements comprising the period 7 in the periodic table are radioactive. In total this period has 32 elements.
Which group contains only radioactive elements?
The actinoids (formerly actinides) are all unstable metallic elements. The period 7 elements with atomic numbers from 89 (actinium, for which the group is named) through 103 comprise these elements. A link can be found below.
What element has the fastest radioactive dcay period?
uranium get d fastest decay period
What is the purpose of radioactive implants?
With the use of radioactive implants, the tumor is subjected to radioactive activity over a longer period of time, as compared to external beam therapy.

What is the radioactive element in period 5?
technetium (Te)
Why are most atoms in period 7 synthetic and radioactive?

Is it true that The length of time required for half of the radioactive atoms in a sample to decay is its period?
It's period of half of decay.
Is oxygen stable or radioactive?
Oxygen, under normal conditions, is non-radioactive. But there are traces of radioactive isotopes present which makes the oxygen slightly radioactive. Additionally, these isotopes have long half-lives, so the radiation given off will not be a lot within a period of time.
What are the release dates for Space Patrol - 1950 Radioactive Cave 3-6?
Space Patrol - 1950 Radioactive Cave 3-6 was released on: USA: 7 February 1953
People who are exposed to radioactive decay over a long period of time are at a high risk of?
Cancer
