Are we made of waves?
Are we made of waves? Radio waves are obviously waves. Only when we come close do we notice that this object is actually a wave. Summary: With quantum theory, we find a beautiful unification: instead of there being two fundamental entities (particles and waves), there is only one fundamental entity: waves. Does Matter diffract? All […]

What function does the nucleolus perform? The nucleolus is a dynamic membrane-less structure whose primary function is ribosomal RNA (rRNA) synthesis and ribosome biogenesis. What […]
What is the relationship between valence electrons and bonding?
What is the relationship between valence electrons and bonding? Valence electrons are outer shell electrons with an atom and can participate in the formation of chemical bonds. In single covalent bonds, typically both atoms in the bond contribute one valence electron in order to form a shared pair. The ground state of an atom is […]
Do elements in a period share chemical properties?
Do elements in a period share chemical properties? All elements in a row have the same number of electron shells. Each next element in a period has one more proton and is less metallic than its predecessor.
