Metals that are less reactive than alkaline metals and alkaline earth metals are called what?
The periodic table goes from left to right if your looking for re-activity (with the exception of hydrogen). Lithium, Sodium, Potassium, Rubidium, Cesium, and Francium are the most reactive elements. The Noble gases are the least reactive elements which include Argon, Neon, Helium, Krypton, Xenon, Radon, and (arguably) Ununoctium. Hope that helps!
Early uses of cesium?
The most common early use of Cesium was to evacuate oxygen from vacuum tubes. It is currently used for many things, including subjects from density measurements to cancer treatments.
What is the pronunciation rebus of Cesium?
The pronuciation is cal-ci-um. For "cal" you can use somebody shouting to another person. For "ci" you can use sea. For "um" you can use a person with a thinking puzzle.
How many elements start with letter C?
There are twelve from the periodic table of elements: Californium Cesium Curium Carbon Calcium Chlorine Chromium Cobalt Copper Copernicium Cadmium Cerium
What are the chemical properties of gold?
Gold is called a noble metal because it resists reacting with stuff. But it can be "convinced" to react, and it forms numerous compounds. It's oxidation states range from -1 to +5, with +1 and +3, Au(I) and Au(III), far and away the most common. Gold will dissolve in Mercury, but creates an amalgam rather than react with it to create a compound. Aurum (gold) resists most acids, though aqua regia (a 3:1 mix of concentrated hydrochloric and nitric acids) will attack gold, as will cyanide. In the unusual -1 state, gold will form compounds like CsAu (cesium auride). It will hook up with the most reactive of the Group 1 and Group 2 elements, the Alkali and Alkaline Earth elements. Remember that the activity of these elements increases as you go down the column. That's just the opposite of the Group 17 elements, the halogens (fluorine, chlorine, etc.), whose reactivity increases as you go up the column. Speaking of the halogens, the Group 17 elements, will react with gold (Au), and auric fluoride (gold fluoride, AuFl) and auric chloride (gold chloride, AuCl) would be examples. Gold will form compounds in its +1 oxidation state with other ions, and it will also similarily form a number of compounds in the +3 oxidation state. There are also compounds (cluster compounds) where gold will form a compound that includes both the +1 and +3 oxidation states of the metal. It has "dual" (fractional) oxidation states in a single compound. Links are provided for more information.
Which one is the most reactive metal potassium lithium or sodium?
Cesium. Cesium is the bad boy of the alkali metals, a period that's just jam-packed with seriously nasty elements. Cesium is reactive enough that if you were to put some water into dry ice, and wait till the ice got that cold itself before putting some cesium on it, the cesium would still react with it! Here's a remembrance: the higher an alkali metal's atomic number, the more reactive it is.
Which one of the alkali metals is the most reactive?
cesium and francium ! lithium is the least reactive
What Group 1A elements is the most reactive cesium potassium lithium or sodium?
cesium
What are the metal in group I on the periodic table?
Lithium(Li), Sodium(Na), Potassium(K), Rubidium(Rb), Cesium(Cs) and Francium(Fr) These are the group one metals known as alkali metals and are highly reactive with water.
What are the very reactive metals that are in the first group of the periodic table?
The first group of the periodic table contains the reactive alkali metals: lithium, sodium, potassium, rubidium, cesium, and francium.
Example of an alkali metal?
lithium, sodium, potassium, rubidium, cesium and francium
Is an lithium an metal?
Yes, along with Sodium, Potassium, Rubidium, Cesium and Francium, Lithium is an alkali metal.
What represents the most reactive metals?
Cesium is the most chemically reactive metal
List all the alkali metals?
Lithium Sodium Potassium Rubidium Cesium Francium
Which elements are designated as the alkali metals?
lithium, sodium, potassium, rubidium, cesium, and francium
What are sodium lithium and rubidium collectively known as?
Lithium, sodium, potassium, rubidium and cesium are collectively known as the alkali metals.
Which is more reactive lithium or carbon?
Reactivity of any metal depends on its capacity to loose electrons as quickly as possible. Among Lithium, Copper and tungsten, lithium is the most reactive since it looses electrons very quickly and forms its cation. In fact, it is among the most reactive metals.
