Answer:
Electrons
Explanation:
In an atom there would be three subatomic particles: Neutrons, electrons, protons. The smallest and lightest in terms of mass is electrons. This is because the nucleus is comprised of the protons and the neutrons, these have a greater mass than electrons as electrons has very little mass that can considered to be 0.
In order to obtain the empirical formula, first divide each
element by its molar mass which can be found in the periodic table. The answer
in the first step would be the number of moles of each element. Then divide
each element with the lowest number of moles obtained in the first step in this
case Phosphorus had the lowest number of moles. Then round it up to the nearest
whole number. The empirical formula then is Phosphorus pentafluoride or PF5.
Answer:
that light is on the electromagnetic spectrum
Explanation:
this is because In physics, the term light sometimes refers to electromagnetic radiation of any wavelength, whether visible or not. In this sense, gamma rays, X-rays, microwaves and radio waves are also light. Like all types of EM radiation, visible light propagates as waves. However, the energy imparted by the waves is absorbed at single locations the way particles are absorbed. The absorbed energy of the EM waves is called a photon, and represents the quanta of light.
Answer : 
is the molecule that exhibit dipole-dipole forces as its strongest intermolecular force.
Explanation : The shape or geometry of given molecules of 
, 
, 
, 
and are linear, linear, tetrahedral, trigonal planar and angular respectively.
The given molecules , , , are symmetrical molecules. These symmetric molecules cannot exists as dipole even they contain polar bonds. Thus, these molecules will not exhibit dipole-dipole forces.
molecule has polar bonds and unsymmetrical bonds as shown in attached image. This molecule cannot exhibit H-bonding. It exhibit only dipole-dipole forces.
Therefore, molecule exhibit dipole-dipole forces as strongest intermolecular force.
Radioactivity refers to the natural transmutation, whereas transmutation refers to the change of one chemical element into another
