Chemestry Notes: - development of periodic table, organization of elements, atomic structure, and modern periodic table, isotopes, summary of chapter

1.1 The development of the biyearly table nuclear modus operandi: the number of confirmatory charges or protons in the nucleus of an fraction of a devoted broker, and whence in like manner the number of electrons norm completelyy surrounding the nucleus. Atomic Mass: the mint of an isotope of an element measured in units one time base on the can of one hydrogen section taken as a unit or on 1/16 the mass of one oxygen atom, save after 1961 based on 1/12 the mass of the carbon-12 atom. Isotope: either of dickens or more forms of a chemical substance element with the aforesaid(prenominal) nuclear number but different poesy of neutrons. Mass number: the number of protons and neutrons in the nucleus of an atom of a crabbed substance. Radioisotope: a particular form of a chemical element (isotope) that is radioactive Specific intricates we make argon uptakeful not because of what they produce, but because of the properties they produce. and then the reason we use iron oxide (fe2o3) in videotape, floppy disks, and unassailable drives. The properties such compounds as this form depend on their mend in the periodic table. This is not what the best part of chemical science is, as we already know these things, but most kindle is what we have yet to discover, such as a compound that entrust conduct electricity without resistance at live temperature.

This would modify faster computers, better MRIS and levitating mass transit vehicles, all would also have a substantially lower capacity use. The shaping of elements It was realized that from each one element had a grapheme mass in the 18th centur y. Hydrogen was given the atomic mass of 1 b! ecause it was the element with the lowest mass, all another(prenominal) elements thereafter were compared to that of hydrogen, this gave a relative atomic mass for each element.
