Yes, but it is not mandatory.
yes
crystalline
NaCl
No, diamond is a covalent network solid.
Molecule movement is the smallest in a solid. In a solid, the molecules are closely packed and have limited freedom to move and vibrate. In liquids and gases, the molecules have more space and freedom to move, resulting in greater molecular movement.
It all depends on which molecule you have.
a molecule is a gas,solid, or liquid
ice is not a molecule because its not a inorganic solid

they vibrate around fixed points
Liquid
Iodine at room temperature is a solid. At room temperature, it sublimates into a gas that can be detected by smell.
