Explanation:

In the 18th - century, the understanding of atoms was more basic. The concept of electrons orbiting the nucleus in electron - clouds was part of later atomic theories (such as the Bohr model and quantum mechanical models which came much later). Elements are composed of atoms, and atoms can combine to form more complex substances, and all matter is made of atoms, which were more well - understood concepts by the 18th century.

Answer:

Electrons orbit the nucleus in electron clouds
