The structure of the atom

The atom

An atom is the smallest particle of a chemical element in which the properties of the element are preserved.

What do you know about the structure of the atom?

The structure of the atom

The atom has Two Parts
Nucleus
Electron Cloud

The structure of the atom

An atom has three particles:

Electrons
Protons
Neutrons

The nucleus

There are two types of particles in the nucleus: protons and neutrons.

Electrons

Moving at very high speed around the nucleus

What is the size of an atom?

Ten billionth of a meter

That means - small. Really really really really really small

0

The difference between the elements

Different elements are made of different atoms

Gold is made of gold atoms
And hydrogen is made of hydrogen atoms

In the number of protons!

The number of protons in the nucleus determines the type of atom and its atomic number

Atomic number - the number of protons in the nucleus

So how many electrons are there?

A neutral atom has an equal number of protons and electrons.
