What defines an element? How many naturally occurring elements exist?

Interpretation Introduction

Interpretation:

The term ‘an element’ is to be defined and the number of naturally occurring elements is to be determined.

Concept Introduction:

Atom is also known as the building block of chemistry.

An atom is made from the particles which are known as electron, proton, and neutron.

The two main parts of an atom are the electron cloud and the nucleus.

Explanation of Solution

An element is a substance which cannot be decomposed into a simpler substance by any chemical methods.

An atom consists of protons, electrons, and neutrons. The electron is a negatively-charged particle of the atom, whereas the proton is a positively-charged particle of the atom. The neutron is a neutral particle which has no charge.

The heaviest naturally occurring element is uranium, which has atomic number 92...
