Why must scientists use special intruments to study atoms?

Answer 1

Atomic radius of an atom cannot be measured directly. The reason is that atoms are not found in isolation or a single atom is always in unstable form and it wants to make bonds with the other atoms. There are electrons which are present in the outer most shells of the atoms. Therefore, when an atom reacts with the other atom then it can gain electrons (which increases its size of shell) or loses its electrons (decreases the radius of the shell). The atomic radius of the atom is usually considered as the distance of nucleus from the outer most shell and hence if an electron reacts then the atomic radius can be changed therefore, atomic radius is considered as the half of the distance between the nuclei of two atoms forming bond with each other.

or

the uncertainty principal means any measurement made on a system will, in fact, change the system itself and introduce a fundamental uncertainty into measurements of all other Why_the_radius_of_an_atom_cannot_be_measured_directlyof that system. the product of the uncertainty in the position and momentum is greater than, or at best equal to , h/4pi. this uncertainty is, in fact, about 100 times the diameter of a hydrogen atom, so this principal will not even allow us to determine if the electron is within the atom!

Answer 2

Scientists use special instruments to study atoms because atoms are extremely small, at the nanometer scale. Regular optical microscopes are not capable of resolving objects at this scale, so scientists use tools like electron microscopes, atomic force microscopes, and particle accelerators to observe and study atoms. These specialized instruments provide the necessary resolution and sensitivity to investigate the structure and behavior of atoms.

Answer 3

we can not see atoms because they are so small that the electrons can crcle around the atom many tmes. the protons and neutrons in the neucleus are so small there can be lke 300 klograms of oqygen radon or even hydrogyn n your house and not even know it. that just proves that you cant see atoms

Answer 4

-- The nucleus of the atom compared to the size of the whole atom is similar to

a bunch of grapes compared to the size of Texas.

-- If you want to SEE an atom, you would need to shine light on it and then magnify

the image formed by the light that reflects from it ... exactly what you have to do

if you want to see your hand or your car. Unfortunately, the wavelength of your

visible light is something like 70,000,000,000 times bigger than the atom, so it's like

trying to feel the shape of a mosquito with a feeler that's 40,000 miles wide.

-- You could use light with shorter wavelengths, but then the photons of light would

carry enough energy to strip the electrons away from the atom, and the act of

looking at it would change what it looks like.

-- And finally, you'd need a microscope with a magnification of something like

100,000,000,000,000 to make an atom look the size of a mosquito.

Answer 5

It is because the alpha particles are so small, even the best telescope (microscope) could not even see them.
Yes.

Answer 6

Because they are to small to be looked inside of. They are much smaller than a period

Answer 7

Atoms are very small. An atomic Microscope is powerful enough to almost see an atom, but cannot.

Answer 8

Because atoms may be to small to study directly so they do the best with the information and technology they have.
