Answer:
Emission spectrum
Explanation:
The emmison spectrum is unique to every elements
Light consists of electromagnetic radiation of different wavelengths. Therefore, when the elements or their compounds are heated either on a flame or by an electric arc they emit energy in the form of light.
The color band indicate the amount of energy emitted in form of electromagnetic radiation.
When electrons in an atom gain energy, the become excited, on falling and losing their energy, they return to their ground state releasing the measure of energy they absorbed in transitioning.
A. Molecular solids tend to have lower melting points than Ionic so it would be Ionic if it weren't for Molecular.
I would say that it is Meteors, Meteorites, and comets. (METEORS may be wrong)
Answer:
The ratio is
Explanation:
From the question we are told that
