What are 5 isotopes?

Examples of radioactive isotopes include carbon-14, tritium (hydrogen-3), chlorine-36, uranium-235, and uranium-238. Some isotopes are known to have extremely long half-lives (in the order of hundreds of millions of years). Such isotopes are commonly referred to as stable nuclides or stable isotopes.

What are 5 uses of radioactive isotopes?

Different chemical forms are used for brain, bone, liver, spleen and kidney imaging and also for blood flow studies. Used to locate leaks in industrial pipe lines…and in oil well studies. Used in nuclear medicine for nuclear cardiology and tumor detection. Used to study bone formation and metabolism.

What are the types of isotopes?

There are two main types of isotopes: stable and unstable (radioactive). There are 254 known stable isotopes. All artificial (lab-made) isotopes are unstable and therefore radioactive; scientists call them radioisotopes. Some elements can only exist in an unstable form (for example, uranium).

What are carbon-12 carbon-13 and carbon-14?

Carbon 12, 13 and 14 are carbon isotopes, meaning that they have additional neutrons: Carbon 12 has exactly 6 protons and 6 neutrons ( hence the 12 ) Carbon 13 has 6 protons and 7 neutrons. Carbon 14 has 6 protons and 8 neutrons.

What are the types and applications of radioisotopes?

Radioactive isotopes have many useful applications. In medicine, for example, cobalt-60 is extensively employed as a radiation source to arrest the development of cancer. ... Another medically important radioactive isotope is carbon-14, which is used in a breath test to detect the ulcer-causing bacteria Heliobacter pylori.

Why are some isotopes radioactive?

Radioactive isotopes decay spontaneously because their nuclei are unstable. ... According to the theory, If the ratio of neutrons to protons more than one, or becomes too large, the isotope is radioactive or the atomic number is above 83, the isotope will be radioactive.

What is radioactive in chemistry?

As its name implies, radioactivity is the act of emitting radiation spontaneously. This is done by an atomic nucleus that, for some reason, is unstable; it "wants" to give up some energy in order to shift to a more stable configuration.

What are the different types of radioactive particles?

There are four major types of radiation: alpha, beta, neutrons, and electromagnetic waves such as gamma rays. They differ in mass, energy and how deeply they penetrate people and objects.

What are the 3 main types of radiation?

The three most common types of radiation are alpha particles, beta particles, and gamma rays.

Why is carbon-13 stable?

Isotopes of Carbon

The next heaviest carbon isotope, carbon-13 (¹³C), has seven neutrons. Both ¹²C and ¹³C are called stable isotopes since they do not decay into other forms or elements over time.

What is iron 55 used for?

It is an X-ray emitter, used as a source of X-rays in various scientific analysis techniques, such as X-ray diffraction. Iron 55 is also used for the study of iron metabolism.

What are isotopes Class 9?

Isotopes: Isotopes are atoms with the same number of protons but that have a different number of neutrons. Since the atomic number is equal to the number of protons and the atomic mass is the sum of protons and neutrons, isotopes are elements with the same atomic number but different mass numbers.
