To give you an idea they are measured in Å :
1/10,000,000,000 (one ten billionth) of a meter (1×10−10 m)
yes
yes , you can not see them because they are tiny. they are more tiny than dust
Molecules are very tiny particles.It comes from the word which means "mass".
There are millions of molecules in a tiny dot. Molecules are so tiny that it is not humanly possible to see it with your eyes unless of course you are using a scientific device. There are more molecules in your body then we can count, making it there fore impossible to know how many molecules are in someone's body
Nutrient molecules pass from the small intestine into the through tiny structures called villi.
atoms
Atoms are the tiny particles that make up molecules. Atoms are composed of protons, neutrons, and electrons. Molecules are formed when atoms combine together through chemical bonds.
The latex balloon and to a lesser extent mylar, also, is actually porous and has tiny tiny spaces between the latex molecules. The molecules do not fit together with no space between them, and the helium molecules are so small that they are able to fit between the molecules of the balloon and float out and away.
Lysosomes
molecules
Yes, everything is made of tiny particles - if it is an element then the particles are atoms of that element, if it is a compound then the particles are molecules composed of atoms of the elements which make up the compound.
No, particles and molecules are not the same. Particles refer to any tiny piece of matter, while molecules are specific combinations of atoms bonded together.
