What are the 3 most reactive alkali metals?
Francium, Cesium, Rubidium
What are the 3 least reactive noble gases?
Neon, Helium, and argon
How many transition metals are in period 3?
There are 8 transition metals. Elements from V to Cu belong to this.
What two processes are used to extract metals?
There are 3 means of extracting metals that are used more than any others and they are: Reduction with carbon: An ore of a metal which is less reactive than carbon is heated with carbon and the more reactive carbon will separate the metallic element from its ore e.g extraction of Iron in a blast furnace Electrolysis: An electrical current is passed through a solution of the metal ore and the metal is split from its ore and collects at an electrode, this is done for metals more reactive than carbon Extraction by other metals: As some metals are more reactive than the other this can be used to split up the metallic ore, an example of this is the extraction of Titanium which involves the use of several other more reactive metals.
How does the metallic nature and the nonmetallic nature of elements in period 3 change from left to right?
Metallic character decreases as you go across any single period of the Periodic Table. This is because metals are characterized by their ability to lose electrons to form cations; the easier it is to do so, the more reactive a metal is. Non-metals are characterized by their ability to gain electrons to form anions; the easier to do so, the more reactive a non-metal is. As you go across any single period, elements gain an extra valency electron. This makes it harder and harder for those elements to lose their valency electrons, thus becoming more and more non-metallic.
Out of periods 1-3 out of group 1 which is the most reactive?
The most reactive element of part of Group 1 is the one with the highest atomic number. If hydrogen is considered to be in period 1, then the answer to the question is sodium. If instead hydrogen is considered to be in a 0th period, then the answer to the question is potassium.
What groups are reasonably reactive?
the transitional metals (groups 3-12)
What are the 3 most reactive alkali metals?
Francium, Cesium, Rubidium
How many transition metals are there in period 2 how many in period 3?
In period 2, there are no transition metals.In period 3, there are no transition metals.
What does the groups in the periodic table of elements describe?
it describes what are metals, non-metals and what are metalloids (semi-metals) group 1: Alkali Metals (reactive) group 2: Alkaline earth metals (reactive) group 3-12: transition metals group 13-17: non metals group 17: non metal, BUT ALSO a halogen group 18: Noble gases (inert - non reactive) Hope i helped you out, :) Alana
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.
Are atoms with fewer electrons more reactive?
That isn't necessarily true. The Halogens (group 17) follow what you said, but the Alkali metals (group 1) don't. As you go down the column, the elements get more reactive for group 1; Lithium is the least reactive and Francium (speculated) is the most reactive. On the other hand, as you down the Halogens, they do get less reactive. Astatine (speculated) is the least reactive while Fluorine is the most reactive element of them all. Hope that clears up things!
What are the 3 least reactive noble gases?
Neon, Helium, and argon
How many transitions metals are there in period 2?
none because the transition metals are in period 4-7 and group 3-12
How many transition metals are in period 2?
none because the transition metals are in period 4-7 and group 3-12
Which of the following elements is the least reactive?
Helium is least reactive element.It forms no compounds.Platinum is least reactive metal.
What is the boron family classified as?
The Boron family is classified as Metals andMetalloids. They are Group 13 and have 3 valence electrons. The Boron family are solids at room temperature and they are reactive. But, the most reactive are the Alkali Metals. They have a violent reaction with water. Hope this helps! :)
