Which group is more reactive on the periodic table group 1 or 2?
Group 1 elements are more reactive than that of group 2 elements.
The more reactive elements on the periodic table are farther down in the rows. For example, Te, or Tellurium, is in group 16 and row 5. The elements in row 7 are the most reactive, but technically Tellurium, since it is the farthest down nonmetal on the periodic table, would be the most reactive nonmetal, technically making group 16 the most reactive row of the nonmetals.
Is it true that the most chemically reactive metals are in group 1 of the periodic table of elements?
Yes. The most chemically reactive metals are in group 1. To add to that, as you go down the periodic table, in group 1, they become more reactive. Potassium is more reactive than Sodium, and Cesium is more reactive than Rubidium. The same general trend occurs throughout the periodic table. The lower down you go in any given column, the elements are more reactive than the last, and the further left you go in each…
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.
No chromium is more reactive than chromium because it it located farther right on the periodic table than nickel. No chromium is more reactive than nickel because it it located farther right on the periodic table than nickel. No chromium is more reactive than nickel because it it located farther right on the periodic table than nickel. No chromium is more reactive than nickel because it it located farther right on the periodic table than…
As you move left on the periodic table, the elements get more reactive and as you move down the periodic table. Using that thinking the most reactive elements are the Alkali Earth Metals (column 1) and the most reactive element is Francium. The least reactive are the noble gases in the last column- Helium, Neon, Argon etc..
What happens to the reactivity of elements in groups labeled A as atomic numbers increase across a period?
Francium and Flourine are the most reactive elements. Francium is at the bottom, Flourine is at the top. The trend isn't as simple as your question. Elements towards the top of the table "want" electrons more. This means they are less likely to give them up and more likely to "steal." In terms of reactivity, this means that the metals at the top are less reactive and the non-metals at the top are more reactive.
The Group 1 alkali metals are the most reactive from the periodic table. They are the most reactive, because they have only 1 valance (outer shell) electron. Reactivity increases as you go down in the group because as there are more shells as you move down, the proton/nucleus cluster in the centre exert a lesser force of gravity on the more distant valance electron, which causes it to be lost even more easily.
each group of the periodic table consists of elements that resemble each other. for instance Lithium, sodium, potassium, and a few more a grouped together, are called the alkali metals. These are all highly reactive, thus they are in a group. Furthermore group also determines the number of valence electrons are present in some cases. Hope that answered your question.
There is no group named 'you' in the periodic table. the groups in the periodic table are numbered, and have names that identify the general class of elements in that group, e.g. 'halogens'.
