Question

What is formed when two atoms of bromine bond together?

(1) a monatomic molecule
(2) a diatomic molecule
(3) a heterogeneous mixture
(4) a homogeneous mixture

Gold can be flattened into an extremely thin sheet. The malleability of gold is due to the
(1) radioactive decay mode of the isotope Au-198
(2) proton-to-neutron ratio in an atom of gold
(3) nature of the bonds between gold atoms
(4) reactivity of gold atoms

Answer 1

The answer for question 1 is (2) diatomic molecule.

The answer for question 2 is (3) nature of bonds

Answer 2

Question One:
(2) A diatomic molecule

Question two:
(3) nature of bonds between gold atoms

More on question two:
Gold and metals in general are malleable because of the so called "sea of valence electrons", which is generally unstable allowing it to be malleable and conductive.
