Chemistry is a very interesting subject but some students facing difficulties to memorize the periodic table. Here I am going to discuss basic chemistry in my upcoming article.
Atoms are the building blocks of chemistry. They are the smallest component of anything; molecules.
Chemists study the behavior and characteristics of substances. These are called the properties of a substance. All substances are made-ups of tiny particles called atoms. A substance the size of a pinhead contains billions of atoms. If you want to get a high score in chemistry then you can take IP chemistry classes in Singapore.
An atom is the smallest unit of a substance that can exist and retain the properties of that substance. There are over 100 different types of atoms, known as elements. Each element has its own chemical name and a shortened name known as a chemical symbol.
Most symbols are abbreviations of the chemical name, like h for hydrogen. However, some symbols come from other languages. For example, the chemical symbol for gold, Au, comes from its Latin name, aurum.
The states of matter define how things move and how we can differentiate one substance from another.
Substances are divided into solids, liquids, or gases. These are known as the states of matter. It is possible for a substance to move from one state to another.
It is known as a change of state. It normally occurs because of a change in the energy of a substance as a result of heating or cooling.
