An atom doesn't have a frequency. It can vibrate with many different frequencies. It can absorb radiation of different frequencies under different circumstances. For instance, electrons moving between various energy levels absorb and release characteristic frequencies of visible and ultra-violet light, and in a magnetic field radio frequency energy can be absorbed as the nucleus moves from one spin state to another. Bonds between hydrogen and other atoms absorb energies in the infra red. All these things give spectra of various frequencies, not an individual frequency.
The smallest atom is hydrogen.
hydrogen
The atomic number of an atom is the number of protons in that atom. For example, the atomic number of hydrogen is 1 because one hydrogen atom have one proton.
2 atoms of hydrogen & 1 atom of oxygen, hence the formula H2O
One atom of water and two atoms of hydrogen. One oxygen atom and two hyrdogen atoms.

The smallest atom is hydrogen.
The difference between a hydrogen atom and atomic hydrogen is that the "hydrogen atom" represents one atom of the chemical element hydrogen. Atomic hydrogen are isolated hydrogen atoms.
The hydrogen line or "shine" is the frequency (1420.40575177 MHz) or wavelength (21.10611405413 cm) of electromagnetic energy emitted by an excited hydrogen atom. This is not a "shine" in the sense of visible - it is in the microwave frequency range. It is useful in radio astronomy because it passes through dust clouds that block visible light.
high frequency radiation
There is one atom in a hydrogen atom
yes the smallest atom is hydrogen
Hydrogen atom is neutral.
Hydrogen is an atom but the hydrogen molecule is diatomic.H is a single Hydrogen atom, and H2 is a molecule.
an oxygen and a hydrogen atom do not weight the same
the atom with the least mass is the hydrogen atom
A stable atom of hydrogen (H)
