Answer 1

dec >
inc v

def: 1/2 distance between nuclei of 2 atoms covalently bonded

Question 2

Cationic Radius

Answer 2

dec >
inc v

def: radius of a cation

Question 3

Anionic Radius

Answer 3

dec >
inc v

def: radius of an anion

Question 4

1st Ionization energy

Answer 4

dec v
inc >

def: amt of energy req. to remove the outermost electron from an atom

Question 5

2nd Ionization energy

Answer 5

inc > (starts @ group 2, wraps around; max @ group 1)

def: amt of energy required to remove 2nd electron from an atom after 1st electron alr removed

Question 6

3rd ionization energy

Answer 6

inc > (starts @ group 13; wraps around, max @ group 2)

def: amt of energy rec to remove 3rd electron from an atom after 1st and 2nd electrons alr removed

Question 7

Electron Affinity

Answer 7

similar to electronegativity, but poor trends :c

def: v similar to electronegativity BUT an ACTUAL energy charge associated w/gaining of an electron
