LM15-16 Flashcards
Atomic Radius
Radius of neutral atom, size
As shielding increases, atomic radius
increases
As ENC increases, atomic radius
decreases
From lower left to upper right, atomic radius _____
decreases
Ionic radius
Size of ions
More protons result in ______ ionic radius (smaller/bigger)
smaller
More protons cause an atom’s ENC to ______
increase
Electronegativity
An atom’s interest in an electron
From lower left to upper right, electronegativity _______
increases
From lower left to upper right, metallic character _______
decreases
When shielding is high, IE is _______ (lower/higher)
lower
When ENC is low, IE is _____ (lower/higher)
lower
First ionization energy
Energy required to remove the loosest electron from a neutral atom
Second ionization energy
Energy required to remove a second electron / remove from a 1+ cation
From lower left to upper right, IE _______
increases
From lower left to upper right, electron affinity _____
increases
What happens to IE at p2, p3, and p4
The p4 atom has a lower IE than expected, causing it to switch places with p3 in terms of IE
The exception of IE in p2, p3, and p4 can be explained by
Repulsion of the full orbital in p4 to make removing the p4 electron easier
