Atom
Who Discovered Atom?
Atom was first used by the famous Greek philosopher Democritus in 400 B.C.
What is an Atomic Radii?
The atomic radii is defined as the distance between the nucleus and the electrons in the outermost shell of an atom.
Why are Atoms Neutral?
As we know that atoms consist of electrons (negatively charged particles), protons (positively charged particles) and neutrons, and it is electrically neutral because it has an equal number of electrons and protons.
What determines the Mass of an Atom?
The mass of the atom is determined by the nucleons of that atom, i.e. the number of protons and neutrons that the nucleus of the atom has. It is also explained using the mass number of the atom.
Why do Atoms Combine?
Atoms combine to form molecules which are more stable in nature than atoms.
What is the Structure of an Atom?
An Atom is composed of Electrons, Protons and neutrons. The nucleus of the atom consists of protons that are positively charged and neutrons that are neutral. The outer region of atom consists of electrons that are negatively charged.
What is Atom?
Atoms are tiny particles that comprise all the things in the known universe. Atoms of an element are responsible for all chemical reactions occurring in nature. We know that atoms are made up of three fundamental particles namely,
- Electrons
- Protons
- Neutrons
These particles are also called subatomic particles as they are found inside atoms. An atom is the basic building block of matter and all the thing around us is made up of combing atoms in different proportions. Let’s learn more about Atom, its constituents, and its structure in detail in this article.
