Beginning of the Nuclear Energy

Nuclear Energy from Atoms

The beginning of the 20 century, nobody would have believed that atoms could produce massive amounts of energy. The atom was the tiniest particle ever known then. Later, JJ Thomson found electrons and Rutherford showed that iotas which are nothing but atoms can split apart. The search for something new called atomic energy started then. The necessity for energy was increasing day by day. The shortage of fossil fuels and therefore the pollution from their burning were already becoming huge concerns.

In such a situation, scientists found out that atom weapons can produce immense energy that would generate electricity.

By the 1990s, atomic energy had become the second largest important source of power. The creation of electricity isn’t the sole use of atomic energy .

It has various other industrial and medical uses. It can even be used to make deadly weapons.

Where did the thought of nuclear energy emerge from?

The term nuclear energy is familiar to most of the people. We all know a few atomic power plant as well. None of this would be possible if man didn’t determine the secrets within the atoms. Ranging from the 19th century, many scientists worked hard to find out more about atoms. Initially, it had been believed that an atom was the tiniest particle that can’t be divided further. 

Nuclear Energy

Democritus, the traditional Greek philosopher was the primary person to define the atom as the smallest particle. This concept was challenged within the 19th century when scientists discovered charged particles inside the atoms. This led to the detailed study of the structure and nature of atoms and eventually the discovery of nuclear energy

What did J J Thomson discover?

J. J Thomson was an English physicist popular for his précised observations about the nuclear construction. He’s the one who discovered electrons, the negatively charged particles inside the atom. In 1897 Thomson was experimenting with cathode rays. During the experiment, Thomson acknowledged charged particles that were previously not known of.

He observed that these bodies were much smaller than atoms and had a better charge compared to their mass. These particles came to be referred to as electrons later.

Electrons are found around the nucleus of an atom. The electrons orbit the nucleus, similar to the Moon as it orbits the Earth.

 His work was one among the initial studies that aimed toward understanding the composition of the atom. Thomson additionally mentioned other observable facts in regards to isotopes, canal rays, etc.

What are subatomic particles?

Sub Atomic Particles

Atoms are the structure squares of everything around us. Though an atom is extremely small, there are particles that are smaller than an atom.

These smaller particles are referred to as subatomic particles. They can’t be seen with our naked eyes, a bit like atoms and nucleus. 

Electrons, protons and neutrons are the foremost known subatomic particles.. These particles are super-small and are found inside the atoms. A few powers hold together these particles inside a molecule. Among these, electron is that the smallest particle..

An electron features a charge while a proton holds it . Protons and neutrons are made from something referred to as quarks.

Who discovered protons?

When J J Thomson discovered electrons, scientists thought that there must be a positively charged particles inside an atom so as to balance the electrons.

Years later, Rutherford , a British physicist came up with another concept. It contained a replacement feature- a core which occupied a smaller volume than the remainder of the atom.

This core was called the nucleus. Rutherford discovered tiny particles inside the nucleus that gave charge to the nucleus. He called them ‘positive electrons’. The positive electrons were later called protons.

What is the structure of an atom?

To understand how atomic energy works, we first got to understand the structure of an atom.

An atom are often imagined as a cloud with a core and an outer shell. The outer shell or the orbit round the core contains electrons. The inner core of an atom is additionally referred to as nucleus. Protons and neutrons form the nucleus. 

Atoms and Molecules

What are radiations?

We as a whole have found out about radiations in certain structures. you would possibly have even seen cautionary signboards warning against harmful radiations in several places like hospitals and power plants. But what exactly are radiations? 

Let’s make it simple. All objects around us emit heat and energy. Our body also gives out some warmth and energy. The energy that leaves a body within the sort of a wave is understood as radiation.

Radiations are of two kinds ionizing and non-ionizing radiations.

The ionizing radiations are stronger. they will ionize atoms. This suggests that they’re capable of freeing an electron from its orbit. On the opposite hand, non-ionizing radiations are weaker. they’re unable of freeing electrons.
