1.
Atom- The atom consists of a central, positively charged core, the nucleus, and negatively charged particles called electrons that are found in orbits around the nucleus.
2.
Electron- A subatomic particle with a negative electric charge.
3.
Proton- A Subatomic particle with the symbol p or p+ and a positive electric charge.
4.
Neutron- A subatomic Hadron particle which has the symbol n or n 0. Has no net electric charge and a mass slightly larger than that of a proton.
5.
Nucleus- A membrane enclosed organelle found in Eukaryotic cells. It contains most of the cell’s genetic material, organized as multiple long linear DNA molecules in complex with a large variety of proteins, such as histones, to form chromosomes.
6.
Random- Made, done happening ,or chosen without method or conscious decision.
7.
Spherical- A coordinate system for three dimensional space where the position of a point is specified by three numbers: the radial difference of that point from a fixed origin.
8.
Ion- An ion is an Atom or molecule in which the total number or electrons is not equal to the total number of protons, giving the atom a net positive or negative electrical charge.
9.
Edible- Able to eat.
