Believe it or not you're living in a world of chemistry
Matter
Matter has mass, occupies some volume in space, and exists in different states
Subatomic particles
Subatomic particles make up atoms. There're different types of subatomic particles, and they have different properties
Electron Configuration
Let's understand how electrons are allocated in the atom, as this is essential for chemists to predict the chemical properties of elements
Electron transit in hydrogen atoms
The modern way: quantum mechanical model
Electron configuration: with quantum mechanical model
Periodicity
The periodic table tells us some periodical trends in some properties of elements, and we name these trends as periodicity
Periodicity I: the atomic radius
