ATOMS 4U

Why atoms combine ? This is the first questions came to my mind when I started taking interest in Chemistry .  First of all let's understand some basic concept so that it would be more easier for you to understand this . What is atom simply ? Atom is the smallest unit of matter which cannot be broken down further Chemically (but can be broken down into subatomic particles proton, Neutron and electron ).or in more simplified way atom is smallest particle of matter or basic unit of matter . What is Molecule ? Molecule is the smallest repeating unit of a compound (compounds are made up of 2 or more different atoms in fixed proportion).Molecule can be made up of same atoms or different atoms but the only condition is that more than one atoms must be Chemical combined . Why atom combines to form Molecules ? A simple and short answer is that atoms combine to form molecules to attain more stability. How does this happen ? Each atom tries to combine with other atoms , so that n...

Comparison of atom Comparing atom to the real world things will amaze you and  make you more curious towards the Chemistry subject. Let's start with some basic and then move on to the comparison part so that you can easily understand the comparison between Atom with human as well as other things. Basics of Atom   Atom is a basic unit of matter . Atom is made up of three subatomic particles  protons , Neutrons and electrons.  Central core part of  an Atom is called as Nucleus . Nucleus of an atom is made up of protons and neutrons except Hydrogen atom(H1) containing only 1 proton and no Neutron .  Electron revolve around the nucleus in particular orbit . Comparing Atom with Nucleus The size of an atom is about 10^-10 meters and the size of nucleus is about 10^-15 meters . After taking ratio of this two numbers , I  found that atom is  100000  times larger than the nucleus .  Comparing Atom with Earth A simple (not e...
