How many orbits are in the hydrogen atom? As @dextercioby pointed out, the question is at best not correctly formulated. If you are asking how many energy levels, or orbitals, there are in a hydrogen atom, then the answer is infinity. There is no upper bound to the principle quantum...

Assuming that the universe is made up of only hydrogen atoms simplifies the calculation so every atom only has one proton. (Photo Credit : general-fmv/ Shutterstock) The number of atoms in the sun comes to 1.201×1057. We know that there are approximately 1011stars in our galaxy, the Milky...
very low – roughly 9.9 × 10-30grams per cubic centimeter. This mass-energy appears to consist of 68.3% dark energy, 26.8% dark matter and just 4.9% ordinary (luminous) matter. Thus the density of atoms is on the order of a single hydrogen atom for every four cubic meters of volume....
How many \sigma and \pi bonds are in the following molecules? How many double bonds are there in the molecule CH3CHCHC(O)CH3? How many hydrogen atoms are in an unbranched alkene with one double bond and 4 carbon atoms? How many hydrogen atoms are in a cycloalkene wit...

The hydrogen profiles are found to closely follow the N distributions, providing unambiguous evidence for their preferential binding as the dominant mechanism for neutralization of N-induced modifications in the electronic structure of the materials. Though the exact number of H atoms involved in ...
For many years, scientists couldn’t figure out how atoms and molecules combined to make living things. Plants, fish, dinosaurs, and people are made of atoms and molecules, but they are put together in a more complicated way than the molecules in the primitive ocean. What’s more, living ...
