What are the two characteristics of an atom?
Atoms are the smallest fraction of an element that can exist, and still show the characteristics of the element. Atoms themselves are composed essentially of electrons (1 negative charge), protons (1 positive charge), and neutrons (no charge).
Why does each atom have specific properties?
The difference in the number of protons and neutrons in atoms account for many of the different properties of elements. They are the glue that holds atoms together in chemical bonds. The basic electron number is determined by the number of protons.
Why is atomic number unique for an element?
The number of protons in an atom is called its atomic number. This number is very important because it is unique for atoms of a given element. All atoms of an element have the same number of protons, and every element has a different number of protons in its atoms. In the case of helium, the atomic number is 2.
What is the characteristic of compound?
Characteristics of a compound The properties of a compound are different from the properties of its constituents. Formation of a compound is generally accompanied by evolution of energy in the form of heat or light. A compound has a fixed melting point and boiling point. A compound is always homogeneous in nature.
What are the two main types of compounds?
Chemical compounds can generally be classified into two broad groups: molecular compounds and ionic compounds. Molecular compounds involve atoms joined by covalent bonds and can be represented by a variety of formulas.
What are the 4 major types of organic compounds?
Among the numerous types of organic compounds, four major categories are found in all living things: carbohydrates, lipids, proteins, and nucleic acids.
