An atom is the basic unit of matter and the specific structure of an element. The term “atoms” comes from the Greek “indivisible” meaning “indivisible” because the Greeks at the time considered the atom to be the smallest thing in the universe and inseparable. But we now know that atoms are made up of three types of molecules: protons, neutrons, and electrons, and we also know that they are made up of smaller particles, such as quarks. The atom was formed after the big bang 13.7 billion years ago. When the warm, dense universe begins to swell, it cools down and thereafter forms the conditions of quarks and electrons. Quarks are classified as protons and neutron protons, which are integrated into the nucleus. According to the CERN, all of these things happened in the first few minutes of the universe.
The universe took 380,000 years to cool down, enough to slow down the electrons so that the nucleus could capture them to form the first atom. The original atoms were hydrogen and helium, which are still the most abundant elements in the universe. Then, gravity begins to control the gas cloud of the prototype star, which in turn forms a heavier atom (this process continues until today), and when the star’s death explodes, it is an important event called (supernova), its valuable content. Expanded to the entire universe. chemistry analysis
An atom is the smallest unit of matter that contains all the chemical elements of an element. An atom consists of a positively charged proton, a neutral neutron, and a negatively charged electron nucleus, all of which orbit the nucleus. The typical atomic size of the protons and neutrons (if they contain electrons) that make up them is about 0.1 nm, mainly from the white space where the electrons are located, usually smaller ones. Atoms have a similar shape. An aspherical atom consists of two regions: a small nucleus, the center of an atom (containing protons and neutrons), and a region that forms an electron cloud that is focused around the nucleus, which is much larger than an atom. With the exception of hydrogen, most atoms contain these three molecules. An electron, no neutrons. The atomic number refers to the number of positively charged units and protons in the nucleus. A neutral atom contains an equal number of protons and electrons, so the positive and negative charges are balanced, and the number of protons in the nucleus determines the chemical nature of the atom. Electrons determine how an atom interacts with other atoms.
