What is the difference between a molecule and an atom? Difference Between Molecule and Atom.

A molecule refers to the smallest particle that retains the chemical properties of a substance. An atom refers to the smallest particle in a chemical change. An element is a general term for a class of atoms that have the same number of nuclear charges, i.e., the number of protons in the nucleus.

A substance made up of molecules, which are the smallest particles that maintain the chemical properties of a substance. Atoms are the smallest particles in chemical change. Molecules and atoms are both particles that make up matter, very small in mass and volume, separated from each other, and constantly moving, both of which are different in type and number, and are not electrically apparent.

The molecules are always in constant motion, and there are gaps between the molecules.

Structure

Molecular structure, also known as molecular stereostructure and molecular geometry, is based on spectroscopic data to describe the three-dimensional arrangement of atoms in a molecule. Molecular structure largely influences the reactivity, polarity, phase shape, color, magnetism, and biological activity of chemical substances.

The optimal temperature for determining the molecular structure is close to absolute zero, because as the temperature increases, the rotation of the molecule also increases. Quantum mechanics and semi-experimental molecular simulation calculations can derive molecular shapes, and the structure of solid-state molecules can also be determined by X-ray crystallography. Larger molecules are usually present in multiple stable conformations, with higher energy barriers between these conformations in the potential energy plane.

Molecule: There are three definitions of molecules, physicochemical, literary, and mathematical, which in this case refers to mathematical interpretation.

In mathematics, a numerator represents a fraction that is written above the fraction line. In general, the numerator is an integer, and when the numerator is not an integer, it is necessary to use the basic properties of fractions to turn it into an integer.

Primary school definition: the dividend divided by the divisor is equal to the dividend of the divisor fraction, i.e., the dividend in the division is equivalent to the numerator of the fraction.

Denominator: The number or algebraic formula written below the fraction line in the fraction is called the denominator. A fraction whose denominator is a known number is called an integer, and a fraction whose denominator is an unknown number is called a fraction. The denominator should not be zero.

Primary school definition: the dividend divided by the divisor is equal to the dividend fraction of the divisor, i.e., the divisor in the division is equivalent to the denominator in the fraction.

1. The denominator represents a population value, and the numerator represents the ratio of the occupied denominator.

2. In fractions, the number or algebraic formula written below the fraction line is called the denominator, and its meaning is to mean that the unit 1 is divided into several parts equally.

3. A fraction whose denominator is a known number is called an integer, and a fraction whose denominator is an unknown number is called a fraction.

A molecule is a whole that is bound together by the atoms that are composed of atoms according to a certain bonding order and spatial arrangement, and this bonding order and spatial arrangement relationship is called molecular structure. Due to the interaction between atoms within a molecule, the physical and chemical properties of a molecule depend not only on the type and number of constituent atoms, but also on the structure of the molecule.

A molecule is the smallest unit in a substance that is relatively stable and maintains the physicochemical properties of the substance. Molecules are made up of atoms, which are bound together into molecules in a certain order and arrangement through a certain force. In the case of water molecules, for example, the smallest unit that appears is a water molecule (H2O) composed of two hydrogen atoms and one oxygen atom until the properties of water are continuously separated until the properties of water are not destroyed.

Chemically, a molecule is the name of a basic unit of matter that is made up. Mathematically, if a fraction is considered as a division, the dividend is also called a numerator. Literally, it means "member", which means a person of a certain nature, such as ****.

What is the shape of a molecule How do people know the structure of a molecule.

I think: First of all, "some comrades say that molecules in a broad sense include molecules, atoms, and ions", which is reasonable and accepted by everyone in scientific practice. In other words, there are broad and narrow definitions of molecules.

Secondly, "molecule is the smallest particle that retains the chemical properties of a substance" can be understood as for a specific substance (separately), which can be completely understood as: a molecule is the "smallest unit" of "a certain substance" to maintain "its unique" chemical properties, that is, taking iron as an example, the iron element is continuously divided, and the scale is getting smaller and smaller, and at a certain size level, iron happens to still retain all the chemical characteristics of its macroscopic scale, then this scale is the molecular scale of iron. The smallest unit of iron that can still retain the chemical properties of the macroscopic is the "iron molecule", and other substances are analogous; Or understand it on a broad basis. (Note that the molecule is a concept that was introduced by considering the separability of matter, as if you were a member of the family.)

I should have a correct understanding of the above statement, and read the original sentence several times.
