structure of an atom and determine and elements identity.
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 n0. 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.
