The photo above is not to make you feel insignificant, it is only for reference and scale. Depending on your field of view, you would have to be around 100,000 light years away to see this Galaxy using the naked human eye.
In diamond, each carbon atom bonds to four others in a dense network that makes the material the hardest substance known.
First, we need to understand a few terms concerning the atom.
) carbon atoms would fit inside the period at the end of this sentence. If an atom were the size of a football field, its nucleus—which contains about 99.98% of an atom’s mass—would be the size of a tiny seed ! An electron is to a speck of dust as a speck of dust is to the earth!
Ionization is the process by which an atom or a molecule acquires a negative or positive charge by gaining or losing electrons to form ions, often in conjunction with other chemical changes.
Ion is an Atom or a molecule in which the total number of electrons is not equal to the total number of protons, giving the atom or molecule a net positive or negative electrical charge.
But in graphite, each carbon atom bonds only to three others in a much looser arrangement of layers, each of which is weakly bonded to neighboring layers.
Because individual layers of carbon in graphite are so loosely connected, they are easily scraped away, which is why it is used as pencil "lead" for writing.
For example, all carbon atoms have six protons; isotopes of carbon can have 6, 7, or 8 neutrons (Table 1).
Radioactive isotopes (also called , which is an electron, or negatively charged nuclear particle.
Isotopes of a given element carry different numbers of neutrons, or neutrally charged particles, in their nuclei.
The sum of the number of neutrons and protons in an atom's nucleaus defines its approximate atomic weight.
Symbol C An abundant nonmetallic element that occurs in many inorganic and in all organic compounds, exists freely in amorphous, graphite, and diamond forms and as a constituent of coal, limestone, and petroleum, and is capable of chemical self-bonding to form an enormous number of chemically, biologically, and commercially important molecules.
