It is between 1 and 55 Angstroms.
55 Angstroms equates to 5.5 nanometers.
The atomic radii of most chemical elements are in the range 75-250 pm or 0,075-0,25 nm.
The diameter of an average atom is around 20 nm.
Dinosaurs were made up of atoms. Every single object is made up of atoms only. Incidentally most of the animals have same atom in their body. They are there in more or less quantity.
Magnetism is created by the synchronized spins of atoms with unbalanced electron clouds. The lowest energy states for these unbalanced atoms is to align themselves with nearby atoms and spin in unison, creating the magnetic field we are familiar with. Most atoms have balanced electrons, or have electron configurations which do not have low energy states when aligned, thus no inclination to spin together in large groups, and no magnetic field.
Everything! Atoms are in the air, water, and even us ! Atoms are are the elementary chemically indestructible components of any material in the world. Atoms are the bricks of molecules.
the most common element is hydrogen and its molecule of two hydrogen atoms is the most common molecule
the name of the elements are found on most periodic tables and each element is a separate type of atom the number found by an element hereorhere shows the number of atoms of each element the molecule has
The atomic radii of most chemical elements are in the range 75-250 pm or 0,075-0,25 nm.
The diameter of an atom is between .1 and .5 nanometers. A nanometer is one billionth of a meter. The diameter of atoms varies depending on the element.
The Smaller Atoms [H to Ca] are in the [single] Angstrom range.
they are most reactive
From the related links: between about 10 nanometers (most energetic Extreme Ultraviolet) to about 300 nanometers (least energetic Near Ultraviolet). Visible violet light is about 400 nanometers.
large atomic radii and low ionization energies
Since the most common form of CT scan is X-Ray Computerized Tomography, the wavelength is between 0.1 nanometers to 10 nanometers which is the range used to classify x-rays.
Most humans eyes are sensitive to wavelengths between about 400 nanometers and 700 nanometers
The longest wavelengths visible to the average human being are in the range of ~700 nanometers which appears to be red to the human eye. However, I am capable of perceiving the red light that my 2 Logitech cordless laser mice emit at 848 nanometers. I hope I am not damaging my eyesight, but I don't believe the emission spectrum for such a laser would be very wide, so I would bet that 800-820 nm is still in the visible range, at least for younger people. I am 22 years old. the longest wavelengths of visible are red colored
When a compound absorbs light one must think of the mechanism by which the compound absorbs the light. Light is composed of photons. Photons are specific quantums of energy. We measure light by a range of nanometers that correspond with specific color regions of the electromagnetic spectrum. The UV region is 280 to 400 nanometers. Most hetero cyclic compounds absorb radiation in both the UV-A and UV-B regions, particularly in the range of 280 to 350 nanometers, and are highly resistant to photodegradation. The range of photoexcitation (the nm range a molecule absorbs) is associated with both its bond stability and electron configuration.

a Virus is smaller than a bacteria. Viruses are so small that they are measured in nanometers. One nanometer is one billionth of a meter. The smallest viruses are about 20 nanometers in diameter, while the largest viruses are more than 200 nanometers in diameter. The average virus is quite small when compared with even the smallest cells-- those of bacteria CREDITS TO: NORTH CAROLINA 8TH GRADE PRENTICE HALL SCIENCE EXPLORER
