What is the structure of an atom?

The basic structure of an atom consists of a small, relatively large nucleus containing at least one proton, usually containing one or more neutrons.

Nuclear External is an energy level (also called a shell) that contains one or more electrons. Energy levels are often referred to as rings (see the detailed description of Bohr model below).

Neutron has the highest mass and there is no charge. The mass of the proton is slightly smaller than the neutron and is positively charged. The electron has little mass and is negatively charged. Electrons move around the nucleus at the energy level

The atomic Bohr model is the easiest way to show the location of various parts of an atom.

Atomic atomic particle structure: The atom consists of the following particles: proton: proton is a positively charged particle whose proton is atomic mass unit. They exist in the core nucleus of the atomic structure. Neutron: Neutron is not charged. Mass is atomic mass unit. They found that they have protons at the center of the atom. - The concept of green chemistry helps scientists better utilize materials on the earth to better improve our environment from internal collapse. As the population increases exponentially, the use of our natural resources creates tremendous pressure. Therefore, it is necessary to create alternative resources by chemical or mechanical means, and to leak contamination and other problems to the environment.

Water has a very simple atomic structure. This structure consists of two hydrogen atoms bonded to an oxygen atom (Fig. 8a-1). The nature of the atomic structure of water gives the molecule unique electrochemical properties. The hydrogen side of the water molecule is slightly positively charged (see Figure 8a - 1). There is a negative charge on the other side of the molecule. This molecular polarity makes water a strong solvent and its strong surface tension (see the description below for details on these two properties).

Figure 8a-1: The atomic structure of the water (or dihydrogen oxide) molecule consists of two hydrogen (H) atoms bonded to oxygen (O) atoms. A unique way for a hydrogen atom to bind to an oxygen atom results in a negative charge on one side of the molecule and a positive charge in the opposite direction. The polarity of the generated charge attracts water molecules to each other and forms a strong molecular bond. When water molecules undergo a physical phase transition, the molecules are arranged in a distinctly different pattern (Figure 8a - 2). The molecular arrangement (water molecules in solid form) used by ice leads to an increase in volume and a decrease in density. Due to the expansion of water molecules during freezing, ice can float on liquid water.
