The half-life of most radioactive isotopes ranges from fractions of a second to billions of years. Some common radioactive isotopes, like carbon-14 and uranium-238, have half-lives of thousands to millions of years, while others, like iodine-131, have half-lives of only days or even seconds.

What makes two istopes of the same element different?
istopes have different numbers of neutrons and most of their elements have several istopes
What is gamma half life?
Most gold is made up of isotopes that have never been observed to undergo radioactive decay and therefore has no known half-life. Some synthetically prepared isotopes of gold may be radioactive and thus have a half-life, the length of which would depend on the particular isotope.
Half-life of a radioisotope is?
The half-life of a radioisotope is the time it takes for half of the atoms in a sample to undergo radioactive decay. It is a fixed characteristic of each radioisotope and can vary widely, from fractions of a second to billions of years. The concept of half-life is crucial in understanding the rate of radioactive decay and in numerous applications in science and technology.
What is the range of half-lives of different radioactive element?
The range of half-lives for different radioactive elements is vast, spanning from fractions of a second (e.g., technetium-99m with a half-life of about 6 hours) to billions of years (e.g., uranium-238 with a half-life around 4.5 billion years). Each radioactive element has a unique half-life that determines the rate at which it decays into a more stable form.
What is a radioactive in period 6?
A radioactive element in period 6 of the periodic table is Polonium (Po). It is a highly radioactive metal with no stable isotopes. Its most stable isotope, Polonium-210, has a half-life of about 138 days.
What makes two istopes of the same element different?
istopes have different numbers of neutrons and most of their elements have several istopes
What is gamma half life?

Why is radioactive decay measured in half lifes?
The half-life forms a type of clock used to calculate time passed.

What is half life of nitrogen?
The half-life of nitrogen is infinite because it is a stable element. Nitrogen is the most abundant gas in Earth's atmosphere and is not radioactive, so it does not decay over time.
What is the most radioactive of the halogen elements?
Astatine is the most radioactive of the halogen elements due to its high level of radioactivity and short half-life. It is produced by the decay of heavier elements and is rarely found in nature.
Describe about the stability of astatine?
All the isotopes of astatine are radioactive and unstable; the most stable isotope is 210At with a half life of 8,1 hours.
What is the best definition of half-life for a radioactive substance?
It indicates how long it takes for the material to decay.
What is half-life used for?
Half-life is used to measure the rate of radioactive decay of a substance. It represents the time required for half of a quantity of a radioactive substance to decay. This information is important in various fields such as nuclear physics, medicine, and archaeology.
How did element 115 get to earth and how radioactive is it?
Element 115, also known as moscovium, does not naturally occur on Earth. It is a synthetic element created in laboratories through nuclear reactions. It is highly unstable and radioactive, with a relatively short half-life of milliseconds to seconds. Its most stable isotope, moscovium-290, has a half-life of about 220 milliseconds.
