Radioactive elements To discover the cause of radiation, it is often necessary to indicate the structure of atomic elements, each containing neutrons in addition to protons. Neutrons are not charged. They are neutral particles. Protons are positively charged. Protons and neutrons are usually stacked in a minimum of space.
Positive protons in the nucleus repel each other and the electromagnetic force is neutralized by the nuclear forces that attract the nucleus component so that the nucleus remains rigid and does not decompose. This force is greater than the electromagnetic force, but its range of influence is limited to the size of the nucleus, and the range of the electromagnetic force is large so that there is a constant conflict between the electromagnetic force and the nuclear energy. For example, in a uranium nucleus containing 92 protons, the electromagnetic force becomes much larger than the nuclear force, which makes it unstable, causing radioactive decay and decomposing uranium into more stable elements. chemistry analysis
Radioactivity is the release of nuclei from radiation emitted by certain chemical elements (such as uranium) or by one of the following particles or radiation:
The range is high-frequency electromagnetic radiation.
Beta particles are electrons or positrons.
The alpha particle is the nucleus of the yttrium.
When these particles and radiation are emitted, the unstable nucleus becomes a stable nucleus, a process called “radioactive decay.”
Alpha disintegration: the helium nucleus emits an alpha particle which is converted into another atomic nucleus 4 of lower atomic number 2 and lower atomic weight.
Attenuation beta: this type is caused by the emission of electrons or positrons, the electron particles, the emission of electrons increases the atomic number of one, and the emission of positrons reduces the number of atoms of one. Sometimes, a double beta decomposition occurs when beta particles are emitted.
Gamma disintegration: When the gamma-ray is released, the energy level of the nucleus changes.
Electron capture: This is the rarest decomposition method in which electrons are captured or absorbed by protons. As a result, the proton becomes a neutron, then a neutron releases electrons, resulting in a decrease in the atomic number and a constant mass.
