Transcript of All About Krypton
by: Kelli White
Science-Ms. Kittrick The Discovery What does it look like? The Basics Its important because... Facts you didn't know! O-R-B-I-T-A-L-S The Element ~ William Ramsay and Morris Travers two chemists
discovered Krypton in London 1898 color: colorless and odorless gas;
state at room temp.: gas
melting point:-157.3 degrees celsius
boiling point:-153.2 degrees celsius
it is a nonmetal period:4
density: 0.003708 g/cm3
atomic radi:88pm ~ Krypton is commonly used:
photographic flashes used in high speed photography
mixed in some fluorescent light bulbs
mixed with other gases to make luminos signs 1. its used in airports for flashing runway lights
2. can be used by astronauts
3. is good for detecting leaks in closed containers
4. its not as big as the other elements on the periodic table
5. Although it is important enough to be on the periodic table element name: Krypton
atomic number: 36
atomic symbol: Kr
atomic mass: 83.798 ~ Krypton got its name from the greek word 'kryptos' which means 'hidden' atomic number:36
atomic symbol: Kr
atomic mass: 83.798 Its Isotope Time! http://ie.lbl.gov/education/parent/kr_iso.htm (Click the link above... arrow pointing up) Funny Jokes "Physical Chemistry is the study of theories in chemistry.
Chemistry is the study of matter and all its aspects.
Since all science involves matter, and anything interesting in science involves theory,
a physical chemist can study anything interesting in science." "What does a chemist do with a dead body? A: Barium in a Krypton." More funny jokes! Five Fun Facts (F.F.F.) William Ramsay was presented the Nobel Prize in 1904 for the discovery of noble gasses
Krypton-85 can be used to recognize the existence of secret nuclear weapons research
Traces of Krypton are found in meteorites and minerals
Krypton is the lightest of the noble gases
Krypton reacts with Fluorine when combined. In an electrical tube the two elements together create an electrical discharge tube Krypton is Supermans WEAKNESS! Thank you for watching!
