What is the most reactive metal on the periodic table?

Francium, metals are located to the left of the staircase and as you move further left and down, the element more easily loses electrons giving it higher reactivity.

An element is reactive because it is unstable.By reacting with other substances it tries to become stable.\nin case of metals or as u say positively charged elements,say,Li,Na,K...the atomic size is increasing on going down.As the size increases the the nuclear pull for the valence shell decreases,thereby making it easier to lose electrons.Thus,K easily loses electrons as compared to Na or Li and is therefore more reactive.\nin case of negatively charged atoms or non metals,the atomic size is again increasing for eg in case of F,Cl,Br..\nbut the case is opposite here.\nthe atom has to gain one electron in order to become stable.\nthe smaller the atom the more is the nuclear pull for the incoming electron and more readily it is accepted.\nthus in this case,reactivity decreases down the group.

It is the most chemically active nonmetallic element and is the most electronegative of all the elements. Fluorine reacts with most inorganic and organic compounds

Los Alamos national lab has a good periodic table/ elemental factoids.\n\nLanthanum is La.  It is the beginning of the "Lanthanides".

As copper is more reactive than silver it will give up its two electrons to silver ions so when is really happening is:-\n\n2Ag+  + Cu → Cu++ + 2Ag\n\n(The nitrate ions (NO3‾) are passive)

Actually the answer is Tungsten.  Rhenium is close, boiling at 5627c (9,668.93 degrees Fahrenheit), but the king of boiling points is still Tungsten at 5660c (10,220 degrees Fahrenheit)\n\nThere could be others, but many elements don't really stick around long enough for us to test their boiling point.

do the project on electronic configurations of different elements or on the characteristics of each element in the periodic table such as lithium is the metal lighter than water, element with highest affinity is chlorine and things like that. u can do this for each and every element. another thing is that the periodic table has been completed so u can do some project relating to that.

aluminium because its an alkali earh metal and\nfluorine is a halogen

generally gases react differently in changing pressure, they react faster in high pressure and is inhibited by low pressure. the most reactive gas due to pressure and everything elese is FLUORINE (F2), coz its the most electronegative diatomic gas molecule and has smallest bond distance.

depends what the magnesium is for. If this is for a chemical reaction, it's because copper is less reactive than magnesium (it's lower on the activity series list).

All form diatomic molecules, are highly reactive, and as elements are colored.  They can form ionic compounds with electropositive metals, and substitute for hydrogen in hydrocarbons to make a vast array of compounds.  All have stable isotopes except astatine.

oxygen, nitrogen, every fuckin mineral and more on the periodic table...take chemistry

Sodium, Potassium, Barium\n\n As long as the metal is more reactive than magnesium, it will be able to displace magnesium ion.

The element with the largest atomic radius is cesium.  Its electronic configuration is [Xe] 6s1.\n\nFrancium could be larger but I do not believe there is data on its atomic radius yet.

Lithium #3 on the atomic table. has a valence of 1 so it is quite reactive. If this electron is stripped off then by the formula 2n^2 the remaining 2 electrons would be a complete valence and so it is very non-reactive.

Hands down... gallium...\n\nGallium is a silvery metal that melts at 30 degree Celsius... thats 86 degree Fahrenheit... the stuff can be a nice solid chunk sitting on a table, and literally melt through your fingers when you pick it up... its the only substance I am aware of that has a melting point of approximately the temperature of the human body...

You need to look at a Periodic Table. The farther to the left of the table an element is, the more metallic it is.
