scientists described light as a wave because the results of many experiments with light demonstrated that light behaves as a
wave. light is now described as having properties of both a wave and a particl
what is the most likely reason why this change was made?
enough scientists voted to accept the change,
data collected from many experiments could not be explained using waves
a well-known scientist published a paper that described light as a particle.
a single experiment's results demonstrated both wave and particle properties

if the temperature drops and becomes cool

then the atmosphere can be freezing as the water vapor in the air is at maximum (100%) and can be severely cold

also can be snowing lightly as the moisture in the air will start to solidify

and btw this is not chemistry but

the term hydride is commonly named after binary compounds that hydrogen forms with other elements of the periodic table. hydride compounds in general form with almost any element, except a few noble gases. the trends and properties vary according to the type of intermolecular force that bonds the elements together, the temperature, its molecular masses, and other components. hydrides are classified into three major groups, depending on what elements the hydrogen bonds to. the three major groups are covalent, ionic, and metallic hydrides. formally, hydride is known as the negative ion of a hydrogen, h-, also called a hydride ion. because of this negative charge, hydrides have reducing, or basic properties. its special characteristics will be further discussed.
