Chapter One Concepts Flashcards
What does the structural theory of matter state?
That elements form a predictable amount of bonds. For example, Carbon forms 4. Nitrogen forms 3, Oxygen forms 2, and Hydrogen and Halogens form one bond. Becoming Tertravalent, Trivalent, Divalent, etc.
What is it called form atoms to share a pair of electrons?
Covalent Bond
The classification of bonds to covalent, polar, and ionic emerges from what of the atoms?
Emerge from the electromagnetically of the atoms sharing the bonds.
Wave equation emerged when they came up with quantum mechanics. This wave equation is utilized to describe the total energy of an atom. Because we can solve this wave equation, we’re given multiple solutions, helping us understand that atoms exhibit a particular energy level, leading o its energy being quantized.
What 3 principles are used to determine which orbitals are filled by electrons?
- Aufbau Principle
- Pauli Exclusion Principle
- Hund’s rule
What theory tells us that a bond is simply 2 atoms sharing an electron density as a result of the constructive interference of their atomic orbitals? What does that overall produce?
This comes from the valence bond theory, producing a stigma bond.
According to what theory does the atomic orbitals considered mathematically combined to produce new orbitals? And what does it produce?
It comes from the molecular orbital theory and it produces new orbitals called molecular orbitals.
For every molecule, what are the two important molecular orbitals that we pay attention to?
- High Occupied Molecular Orbital (HOMO)
- Low Unoccupied Molecular Orbital (LUMO)
What happens when p orbitals overlap with one another?
They produce a pi bond.
What theory assumes that all electron pairs repeal each other and In doing so, arrange themselves in 3-D space so that it achieves maximal distance from each other?
The Valence Shell Electron Pair Repulsion (VSEPR)
