Explanation:
A) particles are close together in random positions with about equal kinetic energy and intermolecular forces.
These points are about liquid state.
B) particles are close together in fixed positions with low kinetic energy
These points satisfy the qualities of Solid state
C)particles are far apart with greater kinetic energy and low intermolecular forces.
The above qualities are for Gaseous state of matter
A) Liquid
B)Solid
C)Gas
It will be Oxygen . And total 8 protons, 8 electrons and 9 neutrons are present in it.
The answer would be periods 6-7 :)
The answer is 39.948 g/mol so rounded to the nearest ones would be 40.00 g/mol.
