Which groups of elements on the periodic table are very reactive?
The alkali metals (Group 1) and the halogens (Group 17) are very reactive on the periodic table. Alkali metals readily lose their outer electron to form a +1 ion, while halogens readily gain an electron to form a -1 ion, making them reactive in chemical reactions.
Why are alkali metals more reactive than transition 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 differences between alkali metals and transition metals?
1.Both are differ in valency shell electrons 2.I-A are monovalent and II-A are divalent 3.I-A is more reactive then the II-A group . 4.I-A have more electro positive character and II-A have less electro positive character than the I-A group . 5.I-A have less ionization energy and II-A have high ionization energy than the I-A . 6.I-A have very less electro negativity than the II-A group elements. 7.I-A is soluble in water and II-A is insoluble in water . 8.I-A metals are does not react directly with nitrogen but II-A react with nitrogen directly. 9.I-A group elements are strong reducing agents than the II-A group elements. 10.The oxidation values are differ. 11.I-A obtained in solid state but II-A group in solution state 12.Decomposes on heating I-A give only oxygen but II-A group liberates both oxygen and nitrogen .

What are 3 facts about akali metals?
Alkali metals, found in Group 1 of the periodic table, are highly reactive and readily lose one electron to form positive ions. They have low melting and boiling points compared to other metals, with these points decreasing as you move down the group. Additionally, alkali metals are soft and can be cut with a knife, and they react vigorously with water, producing hydrogen gas and alkaline solutions.
What are the elements in group 1 of the periodic table are what metal?
The group one metals or alkalis metals are found in group 1 of the periodic table are very reactive metals. These metals have only one electron in their outer shell. Therefore, they are ready to lose that one electron in ionic bonding with other elements. As with all metals, the alkali metals are shiny and easy to cut and are good conductors of heat and electricity. The alkali metals are softer than most other metals. Caesium and francium are the most reactive elements in this group.
3. Where are the most active metals (alkali &alkaline earth) located?
The most active metals, including alkali metals and alkaline earth metals, are located in groups 1 and 2 of the periodic table, respectively. Alkali metals are in group 1, while alkaline earth metals are in group 2. These metals are highly reactive due to their tendency to lose electrons and form positive ions.
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.

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
Elements of Group 1 Are Called what?
Elements in group 1 are called Alkali Metals, after that group 2 elements are called Alkali Earth Metals, group 3-12 elements are called Transition Elements.
How do you classify a metal as alkali alkaline earth or transition metal?
I'm assuming you're thinking of metals like Stainless Steel, Iron, Copper Wiring. These are compound metals made up of several elements. They aren't Transition, Alkali, or Alkaline Earth, they're just metals. Alkali, Alkaline-Earth, and Transition metals are elements, like Sodium or Cobalt. Alkali metal: These are members of group 1 on the periodic table. They are bases (as opposed to acids) and are extremely reactive. They include Sodium and Potassium Alkaline-Earth metals: These are members of group 2 on the periodic table. The are related to the Alkali metals, but are less reactive. They are also alkalines and found in the earth, as the name suggests. Transition metals: These are the most common metals. They are groups 3-I believe 15. They tend to lack acidic or basic properties. They are also the best at carrying electric currents. Hope I helped!

So, transition metals are less reactive than alkali metals and alkaline-earth metals are.
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 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.
