Lithium‚Sodium‚Potassium‚Rubidium‚Caesium and Francium are all part of group 1.They are metals that can be easily cut.After being cut‚it is shiny but it quickly tarnishes due to the fact that the metal reacts quickly with oxygen or water.The shiny surfaces of Sodium quickly tarnishes more quickly than Lithium and Potassium more tarnishes more quickly than Lithium.This shows that the reactivity increases as we move down the group.

interconnects. The graphene nanoribbons have a current-carrying capacity two orders of magnitude higher than copper at these size scales‚ according to Raghunath Murali‚ a senior research engineer at Georgia Tech. {draw:frame} Composed of thin layers of graphite‚ graphene has been studied by the Georgia Tech team as a potential replacement for copper in on-chip interconnects wires. The graphene nanoribbons have a current-carrying capacity of more than 108 A/cm2‚ which makes them very robust in resisting

What can make the world go boom‚ nuclear fission? While nuclear fission has been used as a bomb in the events of Hiroshima it has been used now to produce 40 million kilowatts of energy per day for every ton of uranium. Nuclear fission is when a heavy nucleus disintegrates into two nuclei approximately equal sizes. In the beginning of our understanding of nuclear fission‚ fission was first used and discovered by two German physicists Lise Meitner and Otto Frisch‚ in 1939. However‚ they were not

Lithium Man 7 looks like a AAA battery and weighs 7 amu. He is silver colored with a red and yellow cape that has the number 3 on it. His best friend is Lithium Man 6‚ who looks exactly like him but a little bit thinner. They both live on 152nd street in Lithos City. Lithium Man 7 lives in house 2‚447. Lithium Man 6 lives in house 1‚817. Lithium Man 6 and 7 are both .534 meters tall. Lithium Man 6 and 7 are 199 years old. They can’t be in the water very long or they will dissolve into lithium hydroxide
