What group in the periodic table are the alkali metals?
Alkali metals are found in Group 1 of the periodic table. This group includes elements such as lithium, sodium, potassium, rubidium, cesium, and francium. Alkali metals are characterized by having a single electron in their outermost shell, which makes them highly reactive, especially with water. They are typically soft, shiny, and have low densities compared to other metals.
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
Which one is the most reactive metal potassium lithium or sodium?
Potassium is the most reactive of the three metals (potassium, lithium, and sodium). It reacts vigorously with water, producing hydrogen gas and heat. Sodium is less reactive than potassium, while lithium is the least reactive among the three.
Which one of the alkali metals is the most reactive?
cesium and francium ! lithium is the least reactive
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.
Name an alkali metal that is more reactive than K Na or Li Name an alkali metal that is less reactive?
Hydrogen (H) is more reactive. Francium (Fr) is less reactive.
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.
Which elements are designated as the alkali metals?
The elements designated as alkali metals are lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr). They are all located in Group 1 of the periodic table. Alkali metals are highly reactive and tend to form ionic compounds with nonmetals.
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
What metals are in alkali?
Alkali metals include lithium, sodium, potassium, rubidium, cesium, and francium. These metals are located in group 1 of the periodic table and are highly reactive due to their tendency to lose a single electron to achieve stability.
List all the alkali metals?
Lithium Sodium Potassium Rubidium Cesium Francium
What elementare in the alkali metal family?
Lithium (Li), Sodium (Na), Potassium (K), Rubidium (Rb), Cesium (Cs), and Francium (Fr) are elements in the alkali metal family. They are highly reactive, soft metals that readily lose their outer electron to become positively charged ions.
What are sodium lithium and rubidium collectively known as?
Lithium, sodium, potassium, rubidium and cesium are collectively known as the alkali metals.
