Question YES NO
Real atoms are not too tiny.    
You can only see atoms under a very special microscope.    
Atoms can be cut.    
Atom means indivisible, which means it can't be divided further or can't be cut further.    
Everything you see around you is made up of atoms.    
Everything is made up of molecules, but all molecules are not made up of atoms.    
Atoms are the smallest units of everything.    
Water is made up of water molecules, but it is also made up of atoms.    
There are two atoms of hydrogen and two atoms of oxygen in each water molecule.    
When molecules join together, they form an atom and when atoms join together, they form a thing.    
In the center of an atom there is the nucleus and it's made up of even smaller parts.    
The smaller parts of the nucleus are called electrons and neutrons.    
Each proton of the nucleus carries a negative electrical charge.    
The neutrons don't carry any electrical charge, like protons.    
The nucleus of an atom has a positive charge due to the protons.    
Electrons are outside the nucleus; they are orbiting around the nucleus.    
Electrons carry a positive charge.    
The total negative charge of electrons is equal to the positive charge of the nucleus.    
An atom is neutral: the positive charge of the protons is neutralized by the negative charge of the electrons.    
The electrons are moving outside the nucleus at a very slow speed.    
Electrons can run away from the nucleus.    
Every atom has the same number of protons, electrons and neutrons.    
Electrons keep moving in shells outside the nucleus.    
Each shell contains an unfixed number of electrons.    
The first shell can have two electrons and the third can have eight electrons.    
The third shell can hold eighteen eletrons.    
The fourth shell can hold up to thirty-two eletrons.    
The outermost shell is called the valence electron.    
Atoms bond with other atoms to form a molecule with the valence electrons in the valence shell.    
Atoms always keep trying to fill their shells.    
An oxygen atom has eight electrons in its second shell.    
A hydrogen atom has only one electron in its outer shell.
