Sodium is under water metal?
No sodium is an extremely reactive metal that reacts violently with water. Sodium is in fact one of only two metals that is less dense than water, meaning that it can float on water. Whether a metal is underwater or not does not change its identity.
Two metals that will float on water and react very quikly to form an alkalis?
Such metals are Sodium and Potassium (and all the alkali metals).
The two most reactive groups of elements in the periodic table are the alkali metals and the what?
The two most reactive groups of elements in the periodic table are the alkali metals and halogens.
Which column contains the most reactive elements?
The first two groups--alkali metals and the alkali earth metals--are the most reactive.
What are the two very reactive non metals?
They are: fluorine and oxygen.
Is it true that transition metals are less reactive than the metals in group one and two of the periodic table?
True
What is the similarities between alkali metals and alkaline earth metals?
AM are in group one and are very reactive, unstable, and has one electron in the outer shell, where as in AEM they are in group two and have 2 electrons in the outer shell.
What two groups are less reactive?
Inert gasses are completely non reactive. The next least reactive would be some where in the middle of the periodic table (probably precious metals).
What element is to be more reactive lithium or neon?
Lithium by far, it is an alkali metal. Alkali metals are known to explode when they are placed in water (hydrogen gas is released). Nitrogen has two electrons to fill, and alkali metals have one electron to give off. Think of it as 2>1. Just know that lithium is more reactive than nitrogen.
Name two most reactive elements in the group alkali metals?
These elements are francium and lithium.
What are two most reactive groups in the periodic table?
The two columns of elements in the periodic table that contain the most reactive elements are columns 1 and 17, the alkali metals and halogens respectively.
Is the alkali metal more reactive than an alkaline-earth metal?
Yes, alkali metals are more reactive than alkaline-earth metals. All atoms want to have 8 electrons in their outer shells. Alkali metals have to give one electron away, where as alkaline-earth metals need to give two away which is less energetically favorable.
