Dr. Knowledge’s first fact for you .
What is the structure of an atom ?
It is important to get an
idea of the structure of an atom
to understand how nuclear energy produced .
Contrary to what ancient Greek believed , an atom is not the smallest
particle of matter .The outer part of a cloud – often called shell or orbit –
of particles called electrons , while
insidethis ‘cloud’ is the inner core or nucleus . The nucleus is again made up
of particles called protons and neutrons .
There are even smaller particles moving around in atoms . These super –
small particles can be found inside the protons and neutrons . Scientists have
many names for those particles , but they are usually known as nucleons and
quarks .
Protons are positively charged , while electrons are negatively charged
, and neutrons have no charge at all .
