The periodic table of elements arranges all of the known chemical elements in an informative array. Elements are arranged from left to right and top to bottom in order of increasing atomic number. Order generally coincides with increasing atomic mass. The rows are called periods.
Chromium is a metal in nature. So when one chromium is
bonded to another chromium, there is a weak intermolecular forces which helds
them together which we call as “metallic bonding”.
Metallic bonding is the intermolecular force of attraction which
exist between valence electrons and the metal atoms. It is considered as the
sharing of various detached electrons between many positive ions, whereby the
electrons serve as a "glue" which gives the substance a definite
structure.
Answer: Polar Easterlies
Explanation: Winds flow from high pressure areas to low pressure areas. They originate in the north and south pole creating high pressure zones which generates an outflow. This outflow is then directed from east to west and hence the term used to describe these winds is Polar Easterlies.
The answer would be the third one listed, Refraction
