Do you think elephants are pure

The definition of chemical formula indicates the amount of constituent atoms

Its usage is element symbols and numbers

The composition of pure substances is fixed

Neither symbols nor numbers can be changed

The substance it represents is pure

A substance is expressed by only one chemical formula

Just like an elephant has only one name

Whether ionic compounds or covalent compounds

But some chemical formulas are empirical

Represents the proportion of atoms in a substance

Like two elements in sodium chloride

The number ratio of these two elements is one to one

If elephants are chemically pure

Then there is a unique chemical formula

Considering the proportion of material composition

There is a probability that there will be two expressions

There is also to determine the type of compound first

Is to judge ionic compounds or covalent compounds

But also relate to isomers with different arrangement

Just like isotopes have the same elements

The composition of matter is determined by experiments

A substance made up of molecules is called a molecular formula

But if it's a chemical formula on a simple substance

That number means the number of constituent atoms

If it is in the chemical formula of metallic simple substance

There are solid nonmetallic simple substances

It is directly represented by element symbols

The same is true for rare gases

If elephants are chemically pure

Then there is a unique chemical formula

Considering the proportion of material composition

There is a probability that there will be two expressions

There is also to determine the type of compound first

Is to judge ionic compounds or covalent compounds

But also relate to isomers with different arrangement

Just like isotopes have the same elements

Due to that simple metal and solid nonmetallic structure

It is too complicated so to use element symbols as chemical formulas

There are also rare gases that are directly composed of atoms

As well as simple metal and solid nonmetal

In fact elephants have many chemical elements

If elephants are chemically pure

Then there is a unique chemical formula

Considering the proportion of material composition

There is a probability that there will be two expressions

There is also to determine the type of compound first

Is to judge ionic compounds or covalent compounds

But also relate to isomers with different arrangement

Just like isotopes have the same elements
