What are the reactive groups of fatty acids?
Group 1 the Alkali Metals and Group 2 the Alkaline Metals. Group 1 is more reactive than Group 2.The three major reactive groups of elements are the alkali metals, Alkaline Earth and halogens (these groups are labeled 1 or IA, 2 or IIA, and 17 or VIIIB respectively)
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.
What part of the periodic table is the most reactive and least reactive?
The alkali and alkaline earth metals are the least electro negative elements, and the halogens are the most electro negative elements.
Which 2 groups are the most reactive on the periodic table?
Alkali metals, on the far left side, with 1 valence electron.Halogens, next to the far right side, with 7 valence electrons.These are particularly reactive because they only need to lose or gain one electron to balance their valence band.
Which element in group 2 is the most active?
The ist group elements Alkali metals are most active elements.
Which groups of metals are most reactive therefore never being found free in nature?
Group 1 and group 2 metals
Are groups 1 and 2 more or less reactive in periodic table?
Group 1 elements are the most reactive among metals, followed by group 2 elements.
What is more reactive then silver?
Pretty much every element, apart from platinum and Gold. Elements in groups 1 (alkali metals) and 2 (alkaline earth metals) are usually the most reactive.
What are the reactive groups of fatty acids?
Group 1 the Alkali Metals and Group 2 the Alkaline Metals. Group 1 is more reactive than Group 2.The three major reactive groups of elements are the alkali metals, Alkaline Earth and halogens (these groups are labeled 1 or IA, 2 or IIA, and 17 or VIIIB respectively)
What are two most reactive groups in the periodic table?

Where are less reactive metals nonmetals and metalloids on the periodic table?
in groups 1 and 2 :D
Most of the chemical elements can be divided into 2 groups what are these 2 groups?
metals & non-metals
Why are alkali metals more reactive than transitional metals?
Groups 3-12 do not have individual names. Instead, all of these groups are called transition metals. The atoms of transition metals do not give away their electrons as easily as atoms of the Group 1 and Group 2 metals do. So, transition metals are less reactive than alkali metals and alkaline-earth metals are.
Which 2 groups are the most reactive on the periodic table why?
they
Are the 2 most reactive metals with hydrochloric acid?
Hydrogen and chlorine.
What is the groupe name and number of the second most reactive metals?
Group 2, or the alkaline earth metals.
Which group in the periodic table have extremely reactive metals?
The group I metals (Lithium, Sodium, Potassium, etc.) are very well known for their extreme reactivity. These metals will tarnish quickly in air and can cause small detonations when thrown into water via a highly exothermic reaction that produces flammable hydrogen gas.
