Sodium chloride (NaCl) is an ionic compound that we consume everyday as a table salt, what is the reason that the structure of the ionic compound causes the compound to be hard
and shiny? *

See Explanation

Explanation:

Ionic compounds are composed of crystals. The crystal structure of an ionic compound is responsible for its hardness.

A crystalline solid contains a well organized structure which enables it to be hard and have a particular geometric shape as well defined melting point.

Hence, all the observed characteristics of NaCl are the result of its crystalline structure.

no, the red giant is the hottest with 2.00.000.000 degrees celsius. while the white dwarf only 25,000 degrees celsius.

they it depends on if one believes about radioactivity, they make a geiger counter beep but maybe it was going to beep anyway electronics do wierd things all the time or it was programmed to beep near certain metals.
