What do dinosaurs have in common with atoms?
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.
Why are most materials not magnetic?
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.
What is the size of a virus in scientific notation?
The size of a virus can vary, but most viruses range in size from about 20 to 400 nanometers. In scientific notation, this would be written as 2 x 10^-8 to 4 x 10^-7 meters. Viruses are extremely small particles that can only be seen with an electron microscope due to their size.
What things are made up of atoms?
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.
What are the 2 most common elements and compounds?
the most common element is hydrogen and its molecule of two hydrogen atoms is the most common molecule
What is the range of the radii of most atoms in nanometers(nm)?
The atomic radii of most chemical elements are in the range 75-250 pm or 0,075-0,25 nm.
What is the range of the radii of most atoms in nanometers?
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 range in size of most atomic radii is approximately?
The Smaller Atoms [H to Ca] are in the [single] Angstrom range.
In the alkaline earth group atoms with the smallest radii are?
they are most reactive
What is the wave length of an ultraviolet wave?
The wavelength of an ultraviolet wave typically ranges from about 10 nanometers to 400 nanometers. This places ultraviolet waves just outside the visible light spectrum, which generally ranges from 400 to 700 nanometers.
What is a cat scan wavelength?
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.
How do humans see colors in wavelengths?
Most humans eyes are sensitive to wavelengths between about 400 nanometers and 700 nanometers
What is the difference between ionic and covalent and atomic radii?
Ionic Radii:The distance from the center of the nucleus and the outer most shell (valence shell) of an ion.Covalent Radii:It is one half of the distance between two same nucleur atoms. In hetro nucleur di atomic atoms it is equal to the sum of the two atomic radii.Atomic Radii:The distance from the center of the nucleus and the outer most (valence) shell of an atom.
What is the wavelength range of visible light?
400 (violet) to 700 (dark red) nanometers is the standard range stated in most sources.
What units is the most often used to express the size of microbes?
nanometers
What is the wavelength of visible lights?
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
What would the size of an atom be described in?
The size of an atom is typically described in terms of its atomic radius, which is the distance from the nucleus to the outermost electron cloud. This radius is usually on the order of 0.1 nanometers (1 Ångstrom) for most atoms.
