Electricity & Its Properties: Exploring Valence Electrons & Lightning

Click For Summary
SUMMARY

This discussion centers on the properties of electricity, particularly the role of valence electrons in conductivity and insulation. It is established that while the number of valence electrons influences conductivity, the configuration of these electrons is crucial for determining an atom's ability to conduct electricity. Atoms are generally neutral, with protons and electrons balancing each other, and the ease of electron loss is more dependent on the arrangement of valence electrons rather than their sheer number. Understanding these concepts requires knowledge of quantum mechanics and atomic structure.

PREREQUISITES
  • Basic understanding of atomic structure, including protons, neutrons, and electrons.
  • Familiarity with valence electrons and their role in conductivity.
  • Knowledge of quantum mechanics principles related to electron configuration.
  • Introduction to materials science, particularly semiconductors and their properties.
NEXT STEPS
  • Study the principles of quantum mechanics and electron configuration in atoms.
  • Research the differences between conductors, insulators, and semiconductors.
  • Explore the concept of ionization energy and its relation to conductivity.
  • Learn about the manipulation of semiconductor materials and their applications in electronics.
USEFUL FOR

Students in middle and high school, educators teaching physics and chemistry, and anyone interested in the fundamentals of electricity and material properties.

I am researching electric and magnetic fields, and so far from my understanding each electron produces its own electric field, negatively charged, and thus the atom has its own electric field, am I right so far? Some atoms have better current than others, this is related to the number of valence electrons in each atom. More valence electrons means that the electric field can move from one atom to the other, making the actual substance conductive. Insulators usually have very little valence electrons in their outermost shell. Am I right so far? If you pass an electric current through...

This is where I get confused, just what is electricity, such as lightning? Whats it made of, and how is one large enough to be seen formed?

Exactly.
The terms you are using and the way you are using them shows you are more than a bit confused. Start 'from the bottom' and work upwards and you can get somewhere.

Sir, I am in 8th grade, feel free to point me to the right direction
 
Wikipedia is probably the most easily accessible reference. The problem is that almost everything that you stated is incorrect in one manner or another.

Atoms are generally, on the whole, neutral. The nucleii are made up of neutral neutrons and positively charged protons. The protons have equal and opposite charge as electrons and thus most atoms are neutral since they will attract as many electrons as they have protons (with a few caveats). The ability for the atoms to lose electrons so that they may easily conduct has less to do with the number of valence electrons but the configuration of these valence electrons. This requires a quantum explanation more suitable for at least high school chemistry. Suffice to say though is that there are specific levels and orbitals (configurations) that the electrons can be in. Atoms generally are happiest when they have a fully filled orbital. How their outer orbitals are filled dictate how easily they may ionize and how. So an atom with a sparsely filled outer shell may be a good conductor because it will easily give up its valence electrons. Another atom with an almost full outer shell could also be a good insulator or at least a poor conductor because it does not want to give up electrons but rather hold on to them. But even more important is the overall bulk material as demonstrated by the fact that we can manipulate these characteristics of semiconductors by adjusting their material constituents.
