- Valence electrons are the electrons located in the outermost shell of an atom. They are crucial for determining how an element will react chemically. - In the second period of the periodic table, we have the elements: Lithium (Li), Beryllium (Be), Boron (B), Carbon (C), Nitrogen (...
If one of the electrons in a pair spins upward, the other spins downward. It's impossible for both of the electrons in a pair to spin in the same direction. This is part of a quantum-mechanical principle known as the Pauli Exclusion Principle. Even though an atom's electrons don't ...
These freed electrons create an electric current. The silicon layers of each solar panel are charged differently—one positively with boron and the other negatively with phosphorous. With this setup, solar panels create an electric field. When photons enter this field, they push the electrons out...

The octet rule says that many elements share an octet (8) of electrons in their valence (outermost) electron shell when they form compounds. A formal definition of the octet rule, from Northwestern University, states that "Atoms will lose, gain or share electrons to achieve the electron config...
In nuclear power plants, the chain reactions are very carefully controlled so they proceed at a relatively slow rate, just enough to sustain themselves, releasing energy very steadily over a period of many years or decades. There is no runaway, uncontrolled chain reaction in a nuclear power ...
If each orbital can hold 2 electrons, how many orbitals are there in an s sublevel? How many 2p atomic orbitals from boron must be mixed with a 2s atomic orbital to yield the bonding hybrid atomic orbitals in BF3? Explain how you got your answer. How many electrons can a 3p ...
Mono cells provide more space for electrons to flow, resulting in a smaller, more efficient panel. The downside is they tend to be more expensive. Polycrystalline cells are constructed of many individual shards of silicon melted together. While not as efficient as mono cells, poly cells have ...
