When the atoms of an element have extra neutrons or protons it creates extra energy in the nucleus and causes the atom to become unbalanced or unstable.

Why are some elements radioactive. Why are some elements radioactive and some not. Actually all isotopes are radioactive Some are much more radioactive than others. If the nucleus has an excess of internal energy.

Carbon-14 is an example of a cosmogenic isotope. The reason they dont fly apart is that th. The unstable nucleus of radioactive atoms emit radiation.

There are 118 chemical elements known to humans. The nuclei in which the number of neutrons is more than the number of protons are unstable. The electromagnetic force is very strong and therefore this force is very large.

Atomic nuclei contain protons and neutrons. This is called radioactive decay and isotopes of atoms that do this are called radioisotopes. Every chemical element has one or more radioactive isotopes.

During this radioactive decay is a new atom formed. What causes atoms to be radioactive. The spontaneous decay of an unstable heavier.

For example Uranium 235 has 92 protons and 143 neutrons in its core and is very radioactive. You just studied 19 terms. The stability of a nucleus depends upon the number of protons and neutrons are nearly equal then the nucleus is stable.

Instability Some atoms are unstable. It depends on the stability of the nucleus. Whether an atom is ra.

Answer 1 of 3. Elements are made of atoms. So to make themselves more stable they breakdown or decay and get rid of some matter andor some energy.

Unstable forms emit ionizing radiation and are radioactive. 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. When an atom becomes unstable it typically shoots some protons andor neutrons out of its core.

For example primordial isotopes thorium-232 uranium-238 and uranium-235 can decay to form secondary radionuclides of radium and polonium. Because the strong interaction glue that holds the nucleus together is short-range but the electromagnetic repulsion of all the protons is long-range you end up needing more and more neutrons to stick the nucleus together as you. They have too much energy or the wrong mix of particles in the nucleus.

The process is spontaneous and random. However all elements have an unstable form. Note increasing atomic number doesnt necessarily make an atom more unstable.

This is due to all elements wanting to achieve equilibrium or stability in the nucleus. As nuclei get bigger they get less stable and therefore are radioactive. Why is C 14 unstable.

Why Some elements are naturally radioactive. Why are some isotopes radioactive quizlet. Why some elements are radioactive unstable.

This radioactive element is continually formed in the atmosphere due to cosmic radiation. This list is sorted by increasing atomic number. But protons are positively charged and repel each other.

Radioactive isotopes is a natural or artificially created isotope of a chemical element having an unstable nucleus that decays emitting alpha beta or gamma rays until stability is reached. Whether radioactive elements can become stable and if so how. This is broadly why elements become more radioactive as you move to heavier sections of the periodic table.

A substance is said to be radioactive if it contains unstable nuclei and is able to naturally release energy in the process of shedding high speed charged particles in an attempt to reach a stable state. Typically the most stable form of an element is the most common in nature. Atoms found in nature are either stable or unstable.

Asked by RedDeerGuy1 19291 February 15th 2021 Just wondering. The fact is that some configurations of protons and neutrons are more stable than others thus less radioactive. HERE WE WILL LEARN ABOUT THE RADIOACTIVE ELEMENTS AND THE CONCEPT OF RADIOACTIVE ELEMENTShttpsyoutube_DPhLrFLtbAfollow me on facebookhttpswwwfaceb.

A radioactive isotope also known as a radioisotope radionuclide or radioactive nuclide is any of several species of the same chemical element with different masses whose nuclei are unstable and dissipate excess energy by spontaneously emitting radiation in the form of alpha beta and gamma rays. An atomic atom is a highly order structure. Can any element be radioactive.

The second law states that all highly order structure with break apart and move towards disorder. Atoms are composed of three major subatomic particles electrons protons and neutrons. No affected by a magnetic or electric field.

Radioactivity is the property of some unstable atoms radionuclides to spontaneously emit nuclear radiation usually alpha particles or beta particles often accompanied by gamma-raysThis radiation is emitted when the nucleus undergoes radioactive decay and is converted into a different isotope which may according to its number of neutrons and protons. No Why are some elements radioactive while most elements are not. Radioactivity is dangerous because they can penetrate the skin and damage cells inside.

Instability of an atoms nucleus may result from an excess of either neutrons or protons. There are some elements with no stable form that are always radioactive such as uranium. 94 occur naturally and the remaining 24 are synthetic ones made by humans at some point.

Scientists predict there may be islands of stability in the periodic table where superheavy transuranium elements may be more stable although still radioactive than some lighter elements. Nuclei of atoms are made from two particles. The second law of thermodynamics states that everything goes from order to disorder.

Why are only certain elements radioactive. An atom is unstable radioactive if these forces are unbalanced.
