The document outlines learning objectives for identifying and describing the basic structure of an atom, including the types and characteristics of subatomic particles (protons, neutrons, electrons). It discusses their arrangement within the atom, the concept of atomic number and mass number, and the principle that atoms are electrically neutral due to equal numbers of protons and electrons. Various activities and questions are provided to assess understanding and reinforce the material presented.

1. Learning objective: To be able to Identify

What particles are atoms made of?
Atoms are the building blocks of matter. For some time,
people thought that atoms were the smallest particles and
could not be broken into anything smaller.
Proton- positive Neutron -neutral Electron-negative
Scientists now know that atoms are actually made from
even smaller particles. There are three types:
These particles inside an atom is called as subatomic particles.
How are these particles arranged inside the atom?

How are these particles arranged inside the atom?
Protons, neutrons and electrons are not evenly distributed in
an atom.
The electrons are
spread out around the
edge of the atom. They
orbit the nucleus in
layers called shells.
The protons and neutrons
exist in a dense core at the
centre of the atom. This is
called the nucleus.

● The total number of electrons in an atom is always the same as the number of protons in
the nucleus. This means atoms have no overall electrical charge.
