What is an example of an atom that only exists in its molecular form?
An example of an atom that only exists in its molecular form would be oxygen. It is most commonly found as an O2 molecule.
When a partial electrical charge exists across a molecule it is called a?
Ionic compound
Where are the freezing points and melting points of substances?
They are the same thing. Most commonly the term melting point is used to describe the temperature at which a substance first co-exists in both a liquid and solid state. Freezing point is used usually to describe a substance that is usually liquid at room temperature, such as water. Conversely the term 'boiling point' refers to the first temperature at which the substance exists in both liquid and gaseous states.
How do you know that particles in a gas have more energy than particles of same substance as a liquid or a solid?
We know that for any given substance, and at a given pressure, the gas phase exists at a higher temperature than the liquid phase, which exists at a higher temperature than the solid phase. And temperature measures heat energy per molecule or atom, hence, gas particles have more energy than particles of the same substance in their liquid or solid phase.

An example of an atom that only exists in its molecular form would be oxygen. It is most commonly found as an O2 molecule.
Is oxygen mixture or pure substance?
Oxygen is a pure substance. In nature, free oxygen exists as a molecule of two oxygen atoms covalently bonded, O2.
Is elemental oxygen a mixture?
No. By definition an element is not a mixture.
Is bromine an impure substance?
No, bromine is a pure substance. It is a chemical element with the symbol Br and atomic number 35. It is a halogen and exists as a diatomic molecule in its elemental form.
What substance that commonly exists in water?
It's called H20 isn't it? Two parts hydrogen, one part oxygen.
Is chlorine an atom or a or a molecule?
It is a diatomic molecule, i.e. it exists as Cl2
Is phosphorus a atom or molecule?
Phosphorus is an element that exists as individual atoms. It is not a molecule.
Is sulfur a diatomic molecule?
Sulphur exists as a polyatomic molecule which is S8
Which group 15 element exists as a diatomic molecule at room temperature and pressure?
Nitrogen exists as a diatomic molecule (N2) at room temperature and pressure.
What is the physical form in which a substance exists?
matter
Is bromine a formula unit or molecule?
Bromine is a molecule. It exists naturally as a diatomic molecule composed of two bromine atoms bonded together.
