Alkali metals: Alkali metals are extremely reactive soft metals found in the first column of the periodic table on the left side. Sodium, lithium, potassium, rubidium, francium, and cesium are the six alkali metals. Their outermost subshell contains one electron. Alkaline earth metals: These are...
What state of matter is rubidium? What is nickel's state of matter at room temperature? At room temperature the chemical bromine is in which state? What is aluminum's state of matter at room temperature? What state of matter is molybdenum?
Why can't cesium (Cs) and lithium (Li) be used to cathodically protect rubidium (Rb)? Give reasons why it is important for the percentage atom economy of a reaction to be as high as possible. Why are cast iron and steel used a lot more than pure iron?
Lithium is an element of group 1 having an atomic number is 3. Lithium metal has the lowest mass compared to all the metals and therefore is highly reactive. It is used in pharmaceuticals in mood-stabilizing medicines and batteries as an electrode....
