Simillarities between compound microscope and dissecting microscope

. A compound microscope is a multi-lens, high-magnification, narrow field device designed to focus relatively close to the object/subject observed. The object/subject cannot be easily manipulated other than by mechanical stage.

The dissecting microscope, on the other hand, is a low power, long focal length, wide-field device intended for observing large object/subjects, and; thus, permitting physical manipulation of the object/subject by hand while observing it.

The proton has a positive charge while the neutron has no charge they both make up the nucleus of the atom while the elections have a negative charge and surround the nucleus of the atom. the protons and electrons are used to calculate the atom's mass whereas the neutrons don't affect the mass
