Important Atoms & Electrons ?
Electrons are important for several reasons:
- Chemical bonds form when electrons are transferred/shared between atoms.
- When the outermost energy level of an atom is almost empty, the atom tends to give up electrons. When the outermost energy level of an atom is almost full, the atom tends to grab electrons from other atoms.
- Every time a chemical reaction takes place, electrons are transferred or shared between atoms and therefore energy is shared or transferred.
Most important Atoms for human beings:
- H is Hydrogen atom: 1 electron;
- C is Carbon atom: 2 + 4 electrons;
- N is Nitrogen atom: 2 + 5 electrons;
- O is Oxygen atom: 2 + 6 electrons;
- P is Phosphorus atom: 2 + 8 + 5 electrons;
- K is Potassium atom: 2 + 8 + 8 +1 electrons;
- Ca is Calcium atom: 2 + 8 + 8 + 2 electrons.
