The simplest formula of a chemical compound is a formula that shows the ratio of elements present in the compound in terms of the simplest positive ratio of atoms. The ratios are denoted by subscripts next to the element symbols. Simplest formula is also known as empirical formula.

Chemical compounds can generally be classified into two broad groups: molecular compounds and ionic compounds. Molecular compounds involve atoms joined by covalent bonds and can be represented by a variety of formulas.

Electrons

The Sun

Experts believe that the naked eye — a normal eye with regular vision and unaided by any other tools — can see objects as small as about 0.1 millimeters. Until recently, standard microscopes would allow you to see things as small as one micrometer, which is equal to 0.001 mm.

The smallest thing that we can see with a ‘light’ microscope is about 500 nanometers. A nanometer is one-billionth (that’s 1,000,000,000th) of a meter. So the smallest thing that you can see with a light microscope is about 200 times smaller than the width of a hair. Bacteria are about 1000 nanometers in size.

Human vision can detect single photons or single particles of light, according to a new study showing it is possible for the naked eye to see a particle that is smaller than an atom.
