How many alkali metals are on the periodic table?
6: lithium(Li) ,sodium(Na) , potassium(K) , rubidium (Rb) , cesium (Cs) and Francium(Fr). Practically,only the first five can be termed alkali metals,because there is not enough Francium in the planet to examine its characteristics. Of course, the electron structure of the atom of Francium "proposes" an alkali metal.
Which group of metals on the periodic table is the least stable and consequently its elements are found in nature only in compounds?
The Alkali metals lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr).
What is the radioactive alkali metal?
Francium name by the Curies after france. Yes it is rare and radioactive.
What Element in group 1 on the periodic table is not a metal?
Hydrogen is the only element in Group 1 that is not a metal. The other heavier metals in group one, Lithium, Sodium, Potassium, Rubidium, Cesium, and Francium are all called alkali metals, which are highly reactive since they do not have a full valence shell.
What 2 metals are liquids?
Mercury (Hg) and Bromine (Br) are the only two elements that are a liquid at standard temperature and pressure. Also Bromine is a halogen, not a metal... mercury is the only liquid metal under these conditions.

Where do you find pure rubidium?
Only in chemical laboratories or small scale units for rubidium production.
What room temperature are most metals are in in?
Most metals are solids at room temperature. They're not liquids, and they're certainly not gases. Mercury is the only metal that is a liquid in this temperature range. There are 5 metals that are liquid at or close to room temperature. Cesium, Francium, Gallium, Rubidium, and Mercury.Almost all metals are solid at Room temperature and Pressure, except for Mercury, which is a liquid.
What is group 1 periodic table?
Group 1 on the Periodic Table is called the Alkali Metals, and has only one electron in its atoms' outer shell
What are the elements in the group 1A on the periodic table?
There are 7 elements in group 1: hydrogen, lithium, sodium, potassium, rubidium, cesium, and francium. All of these (except hydrogen) are considered alkali metals. They react very easily with other elements.
Are any pure elements liquids at room temperature?
Mercury is the only metal that is liquid at room temperature. There are other, non-metals that are also liquid at room temp, but I'm not certain which ones.There are 6 metals that are liquids at or near room temperature: Mercury, Caesium (Cesium), Gallium, Bromine, Francium, and Rubidium.
Why is rubidium reactive?
because it only has one electron on its outer shell
What 2 alkali metals have only 1 valence electron?
There are actually three transition metals with only one ionic charge.The three are...Silver(Ag) plus one chargeCadmium (Cd) plus two chargeZinc (Zn) plus two charge
What is the radioactive alkali metal?
Francium name by the Curies after france. Yes it is rare and radioactive.
What is the 2nd most reactive metals?
Sodium, which closely follows potassium, as the attached link reveals. This is for common metal only. Rubidium and Cesium are far more reactive. Francium is even more so but is radiocative. Strictly speaking the answer is Cesium
What are the three weak alkali?
Lithium, Sodium and Potassium are the 'weaker' alkali metals. Rubidium, Caesium and Francium are the most volatile. Francium is only found in micron-grams and is highly radioactive.
