Why hydrogen is an example for atomic emission spectrum and not a molecular spectrum?

H2 does not have dipole moment so there is no allowed transition in infrared between vibrational levels.

What is molecular composition and give an example?
Methane has the chemical formula CH4; hydrogen is 25 % and carbon 75 %.
What is a line spectrum used for?
The line spectrum is usually used to sort out the atomic fingerprint as the gas emit light at very specific frequencies when exposed to the electromagnetic waves. The electromagnetic waves are usually displayed in form of the spectral lines.
Why is the solar spectrum an absorption spectrum rather than an emission spectrum?
The sun has 3 layers - the photosphere, the chromosphere, the corona. Photosphere is the visible surface and gives the absorption spectrum. Chromosphere is the pinkish discharge encircling the Sun, visible only during a total eclipse. This gives the emission spectrum. Corona is the halo encircling the chromosphere. THis gives the coronal spectrum.
Compound water is an example?
Water is a compound consisting of the elements hydrogen and oxygen. The molecular formula for water is H2O.
Empirical and molecular formulas?
The Empirical formula of Al2Br6 is AlBr3.
How do scientists tell difference between elements?
There are many different tests. For example, if you burn some elements they give of light at very specific wavelengths, called an emission spectrum.
Why line spectrum is called finger print spectrum?
It is unique to a specific atom. The emission spectrum of sodium, for example, has two characteristic lines close together in the yellow part of the spectrum, which cannot be found in any other atom. Each line in a spectrum relates to a change in electron state or level.
Is molecular formula a element?
Technically no, molecular formula tells you how many atoms of each element compose a molecule. For example O: oxygen C: Carbon H: hydrogen Carbon dioxides molecular formula is CO2 Atmospheric oxygen is O2 Glucose's molecular formula is C6H12O6
What are binary acids?
a binary acid is a molecular compound in which hydrogen is combined with a second non-metallic element an example would be Halogens acids.
What is hydrogen gas plus oxygen and carbon dioxide?
Hydrogen plus Oxygen can make many different substances. For example, H2O is water. But H2O2 is hydrogen peroxide.
What is the importance of having a symbol for the name of the element?
Symbols are used when showing the molecular structure of a substance, for example the molecular structure of water is H2O meaning that it has 2 hydrogen atoms (H) and 1 oxygen atoms (O)
What is a semi condensed formula?
Is the molecular formula which indicates the main carbon-carbon bonds, or other type of atoms except the hydrogen-carbon bonds Example:
