All metals are highly reactive because of their properties. As you move left on a period while moving down you move close to Francium (most-metallic).
Since group 1 is the most farthest left group, it is the most metallic, therefore the most reactive.
What else can I help you with?
The most reactive element in group 1?
Francium.
In the periodic table which group of element are the most reactive?
group 1
In group 1 in the periodic table which element is most active?
In terms of reactivity, Potassium(K) is the most reactive element among group 1 elements.
What element is most active in group 1?
Fr or Francium is the most reactive alkali metal (group 1)
The least reactive metal in group 1 of the periodic table?
The least reactive metal in Group 1 of the periodic table is francium. Francium is a highly radioactive and rare element that has very little practical use due to its extreme reactivity with other elements.
Most reactive group in periodic table?
The most reactive goup in the metals is the Alkali metals (Group I) The most reactive non-metal group is Group 17 or VIIA) the Halogens. It is difficult to say which of the two groups is more reactive. Chemists will say that Flourine is the most reactive element. Note that Group 18 is the least reactive, most stable.
Which element would you expect to be the most reactive in group 1 and group 2?
In Group 1, cesium (Cs) is expected to be the most reactive element, as reactivity increases down the group due to the increasing atomic radius and the decreasing ionization energy. In Group 2, barium (Ba) is typically the most reactive, as reactivity also increases down this group for similar reasons—larger atomic size and lower ionization energy. Both cesium and barium readily lose their outermost electrons, making them highly reactive.
The most reactive metal among the following is?
The most reactive metals of the periodic table are those that belong to alkali group. Among this group, the more electrons contain each atom of each element, the more reactive it is. This is why Francium is the most reactive of alkali metals.
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 a reactive element in the periodic table?
Alkali metals (group 1) and the Halogens (group 17)
Which of the following groups contains the most reactive elements?
The group containing the most reactive elements is Group 1, also known as the alkali metals. These elements include lithium, sodium, and potassium, which are highly reactive due to their low ionization energies and tendency to lose electrons to form positive ions.
Which group is the most highly reactive metal group?
Group 1, the Alkali Metals, which are extremely reactive.
