What type of nuclear reaction results in a single nucleus undergoing a decrease in atomic number and the release of a helium nucleus?
The nuclear reaction that results in a single nucleus undergoing a decrease in atomic number and the release of a helium nucleus is called alpha decay. In this process, an unstable nucleus emits an alpha particle (helium nucleus) which consists of two protons and two neutrons, causing the original nucleus to decrease in atomic number by 2.
What are the radioactive elements with atomic number from 90 to 103 in the periodic table called?
The elements with atomic numbers from 90 to 103 are called actinides. These elements are known for being radioactive and having partially filled 5f orbital. They include well-known elements like uranium, plutonium, and americium.
What is atomic pollution?
The pollution caused by the emission of harmful radiation from radio active elements which causes harm to the atmosphere and living being even trees is called atomic pollution is usually caused by nuclear waste (incompletely used uranium) of nuclear power plant.
What is An unstable isotope is called what?
It isn't really an ELEMENT that is unstable, but an ISOTOPE. That means that in general, for the same element, some atoms will decay, and some will not - the difference being the number of neutrons in the nucleus.
What word means unstable elements that decay?
The word Radioactive usually denotes a substance containing unstable atomic nuclei.
What are the radioactive elements with atomic number from 90 to 103 called?
The Actinides.

What is the time it takes for the amount of a radioactive parent material to decrease by one-half called?
The time it takes for the amount of a radioactive parent material to decrease by one-half is called the half-life. It is a characteristic property of each radioactive isotope and is used to determine the rate of decay.
What elements that emit atomic particles are called?
Elements that emit atomic particles are typically referred to as radioactive elements. These elements undergo radioactive decay and emit particles such as alpha particles, beta particles, or gamma rays as they try to become more stable.
What are the radioactive elements with atomic number from 90 to 103 in the periodic table called?
The elements with atomic numbers from 90 to 103 are called actinides. These elements are known for being radioactive and having partially filled 5f orbital. They include well-known elements like uranium, plutonium, and americium.
The nuclear product of radioactive decay is called the offspring nuclide. True False?
True. The offspring nuclide is the resulting nucleus that is produced as part of the radioactive decay process.
What is the process by which some substances spontaniously emit radiation?
The process by which some substances spontaneously emit radiation is called radioactive decay. During this process, unstable atomic nuclei release particles (such as alpha or beta particles) or electromagnetic radiation (such as gamma rays) to achieve a more stable configuration.
What is atomic pollution?
The pollution caused by the emission of harmful radiation from radio active elements which causes harm to the atmosphere and living being even trees is called atomic pollution is usually caused by nuclear waste (incompletely used uranium) of nuclear power plant.
What is a negatively charges atomic of molecular ion called?
A negatively charged atomic or molecular ion is called an anion. Anions have gained one or more electrons, resulting in an overall negative charge.
Which element is Atomic number- 112?
The element with an atomic number of 112 is called Copernicium. It is a synthetic, radioactive element that can only occur in a laboratory.
What is An unstable isotope is called what?
It isn't really an ELEMENT that is unstable, but an ISOTOPE. That means that in general, for the same element, some atoms will decay, and some will not - the difference being the number of neutrons in the nucleus.
Half of the total amount of time it takes for all of a radioactive substance to decay is called the halflife of the substance?
okay
