What is the definition of asexual reproduction

Asexual Reproduction refers to a manner in which an offspring is produced by the involvement of a single parent with the offspring produced being genetically identical to the parent.
 
An example of this is binary fission where the parent cell doubles in mass then the organelles is shared in half in the cell and there is a cleaving of the two cells that result in the production of an identical daughter cell.

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
