Atom

Introduction

Every second we are all seeing Something which we cannot see using our naked eyes but it is there. Do you know What is it? It is atom. Yes, atom are very small that we cannot see it using our naked eye. Today, we are going to learn about atoms.

Atom

    A atom: The smallest particle of an element that still has the properties off the element. Atoms are made out of neutron, protons and electron. Atoms are tiny building blocks. Atoms are surrounded by moving electron. The protons and neutrons are present inside the nucleus A proton is a small, positively charged particle. is a particle that has no charge. The nucleus contains almost all the mass of a atom even though it takes up very little space. The rest of the atom is mostly empty space through which electrons move. Electron are negatively charged particles. To see atom you need to use a Transmission Electron Microscope. Some microscopes, such as those in school, uses lenses and light to make images larger. 

Facts:

• Atomic number = protons , electrons
• Protons and electrons are always same in every atom, neutrons can be different.
• Neutrons = Mass number - Atomic number
• Neutrons = Mass number - protons
• Neutrons = Mass number - electrons

Protons:

• Small Positively charged particle

Neutrons:

• Has no charge

Electrons:

• Small Negatively charged particle

Nucleus:

• The protons and neutrons are present inside the nucelus.
