It is the simplest element, having one electron and one proton and was made in the big bang which means it is by far the mist abundant element in the universe, constituting roughly 75% of the Universe's baryonic mass.

Does Mars have Hytrogen?
I guess you mean "hydrogen". Mars doesn't have any significant hydrogen.
What is the most significant force that attracts water molecules to each other?
Hydrogen bonding.
What is the significant force that attracts water molecules polar molecules to each other?
hydrogen bonding
What would be most significant about hydrogen fluoride?
It eats through glass, so you have to be careful how you store it.
How is hydrogen an alterative energy source?
Since there are no significant amounts of free hydrogen, it should be considered more of an energy storage than an energy source. In other words, it takes energy to separate water into hydrogen and oxygen; you get that energy back when the hydrogen is burned.
Are there any places that have a large amount of hydrogen?
Hydrogen is, by far, the most common element in the universe. Stars are mainly hydrogen. If you're asking where the nearest hydrogen mine is, sorry, but hydrogen in elemental form doesn't naturally occur on Earth in significant quantities. We generally make it by electrolysis of water.
Is hydrogen a part of the air?
No. Any significant amount of hydrogen that may have existed either escaped the planet or else combined with oxygen in the atmosphere to form water molecules.
Why do hydrogen bonds matter?
Hydrogen bonds are the strongest of the intermolecular forces that hold molecules together. They are important because the presence or absence of hydrogen bonds determines many physical and chemical characteristics of the compound in question. For example, a molecule with significant hydrogen bonding will have a much higher boiling point than one with no hydrogen bonding.
What is the most significant force that attract polar molecules?
Depending on the exact nature of the polar molecule, the most significant forces would be hydrogen bonding or dipole-dipole forces.
Why do mixtures of acetone and chloroform exhibit significant negative deviations from Raoult's law?
This is because chloroform can hydrogen bond with acetone
What is the purity difference between hydrogen peroxide AR grade and hydrogen peroxide LR grade?
AR is analytical reagent and LR laboratory reagent; practically differences are not significant and depends on the reagents company.
What is the prercent by mass of hydrogen in NH3?
The formula shows that there are three times as many atoms of hydrogen as of nitrogen in the compound. The gram atomic masses are 1.00794 for hydrogen and 14.0067 for nitrogen. Therefore, the percent by mass of hydrogen in the compound is 100{[3(1.00794)]/[3(1.00794) + 14.0067] or 17.7553 %, to the justified number of significant digits.
