Halogens Flashcards
1
Q
Exist naturally as…
A
Diatomic molecules
2
Q
Melting boiling point trend
A
Increases as size increases
3
Q
Reactivity
A
Decreases as size increases
4
Q
Electronegativity
A
Decreases as size increases
5
Q
Are what kind of agent?
A
Oxidizing agents
6
Q
Bond enthalpy?
A
Energy required to break one mole of bonds in gaseous form
7
Q
Bond enthalpy trend?
A
Increase in bond enthalpy as you go up the table, but fluorine is lower as its small atom size means electrons are squished together tightly.
8
Q
What is a halogen halide?
A
Halogen-halogen compound. Thing that is (+) is based on electronegativity. Larger molecules can expand and form octet if needed.
9
