Radioactive DECAY changes an element by ejecting either an electron, proton, or alpha particle. electron particle type of the force of ejection determine whether it is a "beta" particle or a "gamma" particle.29-Aug-2015
How does radioactive decay change an element?
In radioactive decay, an atom will lose protons, and therefore forms new elements. In alpha decay, an alpha particle (a helium nucleus) is emitted from the radioactive atom, and the atom therefore loses 2 protons, and becomes a new element.
How does an element change during alpha decay?
In alpha decay, the atomic number changes, so the original (or parent) atoms and the decay-product (or daughter) atoms are different elements and therefore have different chemical properties.
What occurs during the decay process?
Radioactive decay involves the emission of a particle and/or energy as one atom changes into another. In most instances, the atom changes its identity to become a new element. There are four different types of emissions that occur.
What happens to elements during nuclear decay?
Elements that emit ionizing radiation are called radionuclides. When it decays, a radionuclide transforms into a different atom – a decay product. The atoms keep transforming to new decay products until they reach a stable state and are no longer radioactive.
How can an element change?
Transmutation or nuclear transmutation is a process that involves a change in the nucleus of an atom. When the number of protons in the nucleus of an atom changes, the identity of that atom changes as it is turned into another element or isotope. This transmutation process can be either natural or artificial.
What particle is changed to a new element?
In order to create a new element you have to change the number of protons in a nucleus. It is possible to do this but it requires bombarding various elements, one with the other, by means of high energy particle accelerators.
What happens to electrons during alpha decay?
Thus, when the alpha particle, which carries a positive charge of +2 because of its deficiency of electrons, picks up two electrons to become a helium atom, the entire system in which the decay event occurs remains charge neutral.
How does the nucleus change in beta decay?
Explanation: A beta results in a neutron emitting a high energy electron and becoming a positive proton. Beta decay changes the atomic number of the nucleus by increasing the number of protons, by decreasing the number of neutrons while leaving the atomic mass essentially the same.
How does an element decay?
Radioactive decay involves the spontaneous transformation of one element into another. The only way that this can happen is by changing the number of protons in the nucleus (an element is defined by its number of protons). There are a number of ways that this can happen and when it does, the atom is forever changed.
