There are 92-98 naturally occurring atoms and the rest are synthetic
What is the periodic tale?
The periodic table is a chart that organizes chemical elements into rows and columns
What are the subatomic particles found inn the atom (ad their charge and mass) ?
- Proton: found in the nucleus of the atom, charge of +1 and mass of 1
- Neutron: found in the nucleus of the atom, has a charge of 0 and mass of 1
- Electron: found in the orbital, has a charge -1 and a negligible mass
What is the existence of current due to
The existence of electricity (current) is due to the existing attraction between electrons and protons
Electricity/current is a form of energy exulting from the existence of protons and electrons either statically, which is an accumulation of charge or dynamically as a current/flow of charge
Draw a diagram of static vs. dynamic energy
