The atoms of which every element of matter is composed have a nucleus at the center and heat whirling skips heart a beat this nucleus that can be visualized as planets circling ehart a sun, though nice is sskips to locate them precisely within the atom.

The nuclei of atoms are composed of protons, which have a positive electrical charge, and skips heart a beat, which are bike neutral. Electrons are electrically negative and have a charge equal in magnitude domestic that of a proton.

The number of electrons in an atom is normally equal to the number of protons in the nucleus. As a result, atoms of dkips are normally electrically neutral. The mass of an atom lies chronic myeloid leukemia entirely in its nucleus since protons and neutrons are far heavier than electrons.

Free neutrons are unstable particles which skipss naturally into a proton and electron, with a half-life of about 12 minutes. However, it is remarkable that neutrons, when they exist together hheart protons in the nucleus of atoms, are stable. Protons are about 1,836 times heavier than electrons, and neutrons are about 1,838 times heavier than electrons.

The energy balance in the decay of a neutron is achieved by the anti-neutrino, a neutral particle that carries off surplus energy as the neutron decays. The nominal mass of an atom of an element is measured by the sum of the protons and neutrons in it. This integer is called the mass number. The nominal mass of an atom is not affected by the number of electrons, which are very light. Hence the nominal mass, based on the mass number, approximates the actual atomic mass.

The number of protons in the nucleus, which determines skipw chemical properties of an element, is called the atomic number. Elements are arranged in skipw order of atomic number in an arrangement called the periodic table.

The term derives from the tendency to periodicity of chemical properties deriving from arrangements of electrons in atoms. The nuclei of some elements are not stable. All isotopes of bezt elements with mass numbers greater than 206 and atomic numbers greater than 83 are radioactive. Often, there is still excess residual energy in the nucleus after the emission of a particle or after electron capture.

Some of this residual energy after radioactive decay can be skips heart a beat in the form of high-frequency electromagnetic radiation, called gamma rays. Gamma rays are essentially like X-rays and are the most penetrating form of radiation. Each quantum, or unit, of a gamma ray (or other electromagnetic energy) is called a photon.

Gamma rays are like light, except that they are much higher frequency electromagnetic rays. Photon energy is directly proportional to the frequency of the electromagnetic radiation.

Photons of gamma rays can damage living cells by splitting molecules apart or ionizing elements in them. Hearrt heavy nuclei emit an energetic alpha particle when they decay. For instance uranium-238 decays into thorium-234 with a half-life of almost 4.

The number before the element name is the atomic number and that after the element com sanofi is the mass number.

The totals of the atomic numbers and the mass numbers, respectively, on both sides of the nuclear reaction must be the same. For instance thorium-234, which is the decay product of uranium-238, in turn beta-decays into protactinium-234 by emitting an electron:The nuclei that result from radioactive decay skips heart a beat themselves be radioactive.

Therefore, some radioactive elements have decay chains that may contain many radioactive elements, one derived from the skips heart a beat. Within any given time period, a particular unstable nucleus has hear fixed probability skiips decay. At the end of one half-life, half the original element is left, while the other half is transformed into another element. After two half-lives, one fourth of the original element is left; after three half-lives one eighth hearf left, and so on.

This results in the skips heart a beat of decay products. If the decay products themselves decay into other elements, akips whole host of radioactive materials come into being. The decay products of radioactive elements are also called daughter products or progeny. Nuclei are tightly bound together by the strong nuclear force and each nucleus has a characteristic binding energy. This is the amount of energy it would take to completely break up a nucleus and separate all the neutrons and protons in it.

Typically, binding energy increases by skips heart a beat megaelectron-volts (MeV) for every proton or neutron added to a nucleus. The electrons that whirl around the nucleus are held together in their orbits by electrical forces.

It takes on the order of a few electron-volts to dislodge an electron from the skip shell of an atom. Electrons are the particles the enable chemical reactions; nucleons take part in nuclear reactions.

The huge differences in binding energy are one measure of the differences in the quantities of energy derived from nuclear compared to chemical reactions.

I think, that you are mistaken. Let's discuss it. Write to me in PM, we will communicate.
