When a uranium atom decays radioactivity to become protactinium the radiation emitted is?
Some possible decays:- U-231------------Pa-231 (by electron capture)- U-229------------Pa-229 (emission of a beta particle)- U-228------------Pa-228 (by electron capture)
What is the result of an atom that gains or loses an electron?
An atom that gains an electron becomes negatively charged and is called an anion. An atom that loses an electron becomes positively charged and is called a cation.
What will happen to an atom is an beta particles emits or adds?
If a beta particle is emitted from an atom, it transforms a neutron into a proton, changing the element into one with a different atomic number. If a beta particle is added to an atom, it will create a new element by introducing an additional proton.
How an electron is emitted from nucleus?
Electrons are not emitted from the nucleus. Electrons are negatively charged particles that orbit the nucleus of an atom in specific energy levels. The nucleus of an atom contains positively charged protons and neutral neutrons, but electrons are not emitted from the nucleus like alpha or beta particles.
Sketch an atom emitting light. Does the electron end up in a higher or lower orbit. Repeat for an atom absorbing light?
When an atom emits light, the electron transitions from a higher energy level to a lower energy level within the atom, releasing energy in the form of light. The emitted light has a wavelength corresponding to the energy difference between the two energy levels involved. When an atom absorbs light, the electron absorbs the energy of the incoming photon and jumps to a higher energy level within the atom, moving to a more excited state.
What is the electron emitted from the atom called?
the gamma ray.
What is electron capture?
Electron capture is a process in which an electron is captured by the nucleus of an atom, causing the electron to combine with a proton and form a neutron. This process results in the emission of a neutrino and a lower-energy state for the nucleus. It is a type of radioactive decay that occurs in some unstable nuclei.

What Is geological electron capture?
Electron capture occurs when an electron from the innermost orbital of an atom is captured by a nucleus, which leads to the conversion of a proton into a neutron.
What is a negative electron emitted from the nucleus of an atom at high speed?
beta particle
What is an electron emitted from an atom into two nuclei with smaller masses is?
its called an isotope c:
What is the relationship between the light emitted by an atom in the energies of the electrons in the atom?
The more energy levels the electron jumps the more energy the emitted light will have. The more energy you have the shorter wavelength there is.
How do positron emission and electron capture change an atom?
Positron emission results in the atom losing a proton, transforming the atom into a different element with a lower atomic number. Electron capture involves the atom gaining a proton, resulting in the transformation of the atom into a different element with a higher atomic number. Both processes lead to the formation of a more stable nucleus by adjusting the ratio of protons and neutrons.
How does potassium turn into argon?
Potassium-40 undergoes radioactive decay into argon-40. During this process, a potassium atom undergoes electron capture where a proton in the nucleus captures an inner-shell electron and is transformed into a neutron. The result is the transformation of a potassium atom into an argon atom by emitting an electron and an antineutrino.
Which term describes the particle that results when an electron is added to an atom?
It depends. If you are talking about electron capture at the molecular level, then when a neutral atom (or molecule) absorbs a negatively charged electron, it becomes negatively charged. All charged atoms (or molecules) are called ions, and a negatively charged ion is called an anion. . If, on the other hand, you are talking about electron capture by the nucleus of an atom, then when a positively charged proton absorbs a negatively charged electron, the proton converts into a neutrally charged neutron and immediately emits a neutrally charged electron neutrino.
What is the result of an atom that gains or loses an electron?
An atom that gains an electron becomes negatively charged and is called an anion. An atom that loses an electron becomes positively charged and is called a cation.
What will happen to an atom is an beta particles emits or adds?
If a beta particle is emitted from an atom, it transforms a neutron into a proton, changing the element into one with a different atomic number. If a beta particle is added to an atom, it will create a new element by introducing an additional proton.
