[nitin] represents a shiny metal which can be cut with [a] knife But it will be required to exchange sufficient Force to achieve that Little Rapidly oxidize in Air and while that is happening it's been covered [with] a layer of oxides carbonates and little nitrite black coating because this is the only metal [that] can react with atmospheric nitrogen at room temperature Liam can be stored in Kerosene However due to its low density It will float on each surface now shall We look at some of the chemical properties of Liam a piece of little x another commonly with water forming Hydrogen and lithium hydroxide if you ignite the released hydrogen the flames will turn beautiful red due to lithium ions however if we take liam in the shape of [Findlay] Tinfoil Which is used in leitrim biases by the way that will ignite and explode open reaction with water Which is very dangerous? If you set fire to a little piece of [liter] it will melt and then light up with a very bright white flame to then form little oxide during combustion The temperature of burn [a] [liter] in the air is more than 2,000 degrees Celsius little as well as all other Alkali metals is an excellent reducing agent that easily loses electrons is surprising however That when it's melted a temperature above 300 degrees Celsius It impractically doesn't oxidize with the air and each surface remains below C If you ignite liam on sand it will react with a silicon There's a sand country's of forming an amorphous Silicon in addition little eggs perfectly with sulfur This direction of little with sulfur formed so much energy That even our pan melted on which the reaction was scared and yes I have also built through the carpet with this reaction for that. It's all right I have many carpets the [also] [very] dangerous little Property is that when it starts to burn while being on wood it will pick up oxygen from the cellulose Molecules that make up the aforementioned rule as such lithium explodes creating a lot of course parts Don't try to repeat this experiment also [Liam] can [react] with dry copper sulfate recovering copper from each soul These days liam finds many applications in science and [technology] the most common use of it of course Would be lithium-ion batteries and other power sources also liam is used in Nuclear power lasers as well as Metallurgy little compounds are used in medicine for the treatment of Mental disorders Because of its ability to be an antagonist of sodium ions Subscribe to my channel to see many more of new and interesting you
