Question

1. What does chemistry mean?

As an introduction to chemistry, it is the branch of science that studies matter and change. First,

chemistry deals with the study of the composition and the properties of matter (which is basically any

macroscopic substance that we can observe). Then, chemistry deals with change, or how these

substances evolve when submitted to certain conditions, or how one substance changes

or reacts while interacting with a different substance. The definition of chemistry can’t be made shorter,

since it covers basically everything!

2. When was chemistry “discovered”?

Very simple chemical processes were performed even during ancient history, at 1000 BC, much

before any basic chemistry concepts or laws were actually established. Extraction of metals from ore

or getting compounds out of natural sources such as plants, are examples of chemistry that was first

performed thousands of years ago and are still a thing today.

Alchemy tried to explain the nature, properties and transformations of matter. But it was not

science, but rather a set of myths and magic. It is agreed upon that, the transition from alchemy to

modern chemistry as we know it, started on the 17th century, with the publication of The Sceptical

Chymist by Robert Boyle (1661), who is considered the father of modern chemistry. The difference

between chemistry and alchemy is the application of the scientific method.

3. Why is chemistry important?

Everything is chemistry. Everything that you can observe macroscopically is made of chemicals.

You are made of chemicals, your food is chemicals, you breathe chemicals, we live out of and thanks

to chemicals, everything you see under the sun is a mixture of chemicals.
