In Period 3 of the Periodic Table, the least reactive metals are found towards the right side, specifically in the group of elements that includes aluminum (Al) and silicon (Si). Among these, aluminum is less reactive compared to sodium (Na) and magnesium (Mg), which are located on the left side of the period. However, metals in Period 3 are generally less reactive than alkali metals and alkaline earth metals found in earlier periods.
What else can I help you with?
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 are the 3 most reactive alkali metals?
The three most reactive alkali metals are lithium (Li), sodium (Na), and potassium (K). They are known for their high reactivity due to their low ionization energy and tendency to readily lose an electron to form a positive ion.
What two processes are used to extract metals?
Two processes used to extract metals are pyrometallurgy, which involves high-temperature processes such as smelting, and hydrometallurgy, which involves using aqueous solutions to extract metals from ores.
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.
What groups are reasonably reactive?
the transitional metals (groups 3-12)
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
How many transition metals are there in period 2 how many in period 3?
In period 2, there are 4 transition metals: titanium, vanadium, chromium, and manganese. In period 3, there are 10 transition metals: iron, cobalt, nickel, copper, zinc, yttrium, zirconium, niobium, molybdenum, and technetium.
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.
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.
What are the 3 least reactive noble gases?
Neon, Helium, and argon
How many transition metals are in period 2?
none because the transition metals are in period 4-7 and group 3-12
How many transitions metals are there in period 2?
none because the transition metals are in period 4-7 and group 3-12
What is the 3 most reactive metals?
The three most reactive metals are potassium, sodium, and lithium. They react quickly with other substances, such as water and oxygen, to form compounds. They are stored under oil or inert gases to prevent reaction with moisture in the air.
Difference between s-block metals and d-block metals?
the s-block elements are highly reactive elements, on the other hand, d-block elements are less reactive than the alkai metals and the alkai-earth metals. some are so reactive that they do not easily form compounds.
How many transitions metals are there in period 3?
There are 8 transition metals. Elements from V to Cu belong to this.
