Classification of Matter

Classification of Matter

Classification of Matter. Elements. Note that an element: consists of only one kind of atom, cannot be broken down into a simpler type of matter by either physical or chemical means, and can exist as either atoms (e.g. argon) or molecules (e.g., nitrogen).

Lecture 4b

Lecture 4b. Mass Spectrometry. History . J. J. Thompson was able to separate two neon isotopes ( Ne-20 and Ne-22 ) in 1913, which was the first evidence that isotopes exist for stable elements (Noble Prize 1906 in Physics, Discovery of the electron in 1897)

The nylon tights process

The nylon tights process

The nylon tights process. They heat it up to a high temperature that makes it a semi liquid. Then it meets air and it dries it up. They put the nylon in a spinneret which spins it into a fine thread then they weave it. There is different types of weaving.
