a model of atoms and molecules

Consider a glass jar containing 118 different sorts of construction blocks. Each kind has a distinct color, size, and form. And each symbolizes an atom from a different periodic table element. If you have enough jars, you can utilize the bricks to create anything following a few easy principles. A compound is a collection of blocks. Weaker forms of bonding can also draw one chemical to another. 

Chemical Compounds

These ties are essential. It’s critical. Simply put, they keep our universe together. They also determine the structure of all substances and hence their characteristics. To determine if a substance dissolves in water, for example, we examine its linkages. These bonds will also influence whether or not a material conducts electricity. Is it possible to utilize a substance as a lubricant? Examine its ties once again. 

Chemical bonds are typically classified into two types. Intra bonds are those that connect one building block to another within a molecule. (Intra implies “from within.”) Inter bonds are those that draw one chemical to another. (The term “inter” refers to the space between two things.) 

There are many forms of intra- and inter-bonding. However, electrons govern all bonds, regardless of their kind. 

Electrons are one of the three fundamental subatomic particles that make up an atom. The others are positive protons and electrically neutral neutrons. Electrons are negative. The characteristics of a bond are determined by how they behave. Atoms can exchange electrons with their neighbors. Other times, they may share electrons with that neighbor. Or electrons can move around within a molecule. When electrons migrate or shift, electrically positive and negative regions are created. Positive regions attract hostile areas and vice versa. 

How Bonds Work

Bonds are the attractions that exist between negative and positive places. 

Electrons may be transferred between atoms so that money can be transferred from one person to another. Metallic element atoms are prone to electron loss. They get positively charged as a result of this. Nonmetal atoms tend to pick up the electrons that metal atoms lose. Nonmetals get negatively charged as a result of this. These charged particles are referred to as ions. The attraction of a positive ion and a negative ion results in forming an ionic (Eye-ON-ik) bond. An ionic compound is the outcome of this process. 

Sodium chloride, also known as table salt, is an example of an ionic chemical. It contains positive sodium ions as well as negative chloride ions. The ions’ attractions to one another are all quite strong. It takes too much energy to separate these ions. This property indicates that sodium chloride has a high melting and boiling point. These charges also imply that when salt is dissolved in water or melted, it becomes an excellent electrical conductor. 

A small grain of salt contains billions and billions of these tiny ions attracted to one another in a massive, three-dimensional structure known as a lattice. A few grams of salt can contain over septillion sodium and chloride ions. What is the magnitude of the figure? It is a quadrillion billion times a billion (or 1,000,000,000,000,000,000,000,000).
