chemical bonding Flashcards
what is the valence shell
The shell holding the electrons located the furthest from the nucleus is called the valence shell.
what can atoms valence shell comprise of
Atoms’ valence shells can comprise partially filled or fully occupied orbitals.
what are lone pairs
Pairs of electrons occupying the same orbital are called lone pairs.
in hypervalentcompound by how many electrons can the octec be expanded to
In hypervalent compounds, the octect can be expanded to 10, 12 or even 16 electrons.
Define hyper valencey
Hypervalency - also known as expanded octect - describes a phenomenon where main group elements found in the s-and p-block of the periodic table are found to accommodate more than 8 electrons in their external
where are hypervalent atoms commonly found in
biological moleculels like nucleic acid, ATP, and PTMs
what is a covalent bond
According to Lewis’ theory, a covalent bond is formed when two atoms share a pair of electrons.
