What is the definition of electronegativity?
a chemical property that describes the tendency of an atom or a functional group to attract electrons toward itself
Draw the noble gas notation, electron configuration, and orbital box diagram for:
Sr 2+, Z = 38
.
What is the difference between electron and molecular geometry?
Electron geometry refers to the arrangement of all electron groups (both bonding and non-bonding) around a central atom in a molecule, while molecular geometry only considers the arrangement of atoms
