Test 3 Flashcards
Who does the screening in terms of electrons?
Core electrons screen valence electrons
Effective nuclear charge=
Total number of electrons - core electrons
The higher the L, the further from the….
Nucleus
Which penetrate better S electrons or P?
S
As L goes up, screening goes….., and penetration goes….
Screening goes up, penetration goes down
The trend of increasing atomic radius is….
From right to left and doen
The trend of ionization energy is….
Increasing from up and to th right
Cations are…. Than their parent atoms
Smalller
A ions are….. Than their parent atoms
Larger
In isolectronic ions, what will have the highest attraction and the lowest radius
The ion with the most protons will be the smallest
Which elements have the most negative electron affinity and why
Elements in the 7th main group are most negative because they really want to fulfill its octet
The blank the ions… And the…. Their ionic charges, the stronger the ionic bonds. What does this reference?
Smaller the ions and higher their ionic charges. Lattice energy
Electronegativity will…. As you go…. And to the…. Of the periodic table
Increase, up, right
The least electronegativity atom serves as the… Atom in a Lewis dot structure
Central
F. Ch (fromal charge) =
Valence electrons–(lone pairs + .5 bonding electrons)
