Iodine
If the temperature is below the melting point then the element is a solid.If the temperature is above the melting point but below the boiling point, then the element is a liquid.If the temperature is above the boiling point, then the element is a gas.
At room temperature it is a pale green gas. When dissolved in water it becomes clear/pale green A diatomic molecule which has a very low Melting and boiling point. It is described as a halogen because it is found in group 7
The correct spelling is discrete molecule instead of discreet molecule. A discrete molecule is a molecule that is covalently bonded that has weak bonds. They have a low boiling and melting point.
Water it can melt in the boiling point and in the boiling point the water (ice) practically turns into a liquid (water) then into a gas
Melting Point 2349 K (2076 °C, 3769 °F) Boiling Point 4200 K (3927 °C, 7101 °F)

Melting and boiling points are different for each compound or element.
If the temperature is below the melting point then the element is a solid.If the temperature is above the melting point but below the boiling point, then the element is a liquid.If the temperature is above the boiling point, then the element is a gas.
kelvin
helium
the melting point is 1668 C
hydrogen bonding increases the intermolecular attractions and therefore increases the boiling point and melting point.
At room temperature it is a pale green gas. When dissolved in water it becomes clear/pale green A diatomic molecule which has a very low Melting and boiling point. It is described as a halogen because it is found in group 7
Boiling point, melting point, and density are all physical properties of an element. They determine the state of the element.
