How does reactivity change from an element in group 1 to an element in the same period in group 2?
Reactivity decreases from group 1 to group 2 within the same period. Group 1 elements, like lithium and sodium, are highly reactive due to their single valence electron, which they readily lose to form positive ions. In contrast, group 2 elements, such as magnesium and calcium, have two valence electrons, making them less reactive since they require more energy to lose both electrons. Consequently, while both groups are reactive, group 1 elements are generally more reactive than their group 2 counterparts in the same period.
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.
Do group 1 metals contain reactive or unreactive elements and why?
Except hydrogen, elements in group 1 are very reactive at they can give away their only electron in their valence shell easily to be ionized.
Are period 1 elements more electronegative than period 2 elements?
No, period 1 elements are not more electronegative than period 2 elements. Electronegativity generally increases across a period from left to right, so elements in period 2 are generally more electronegative than elements in period 1.
How many elements in the first period?
Period 1: 2 elements Period 2: 8 elements Period 3: 8 elements Period 4: 18 elements Period 5: 18 elements Period 6: 32 elements Period 7: 25 elements
What part of the periodic table is the most reactive and least reactive?
The alkali and alkaline earth metals are the least electro negative elements, and the halogens are the most electro negative elements.

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.
Would a metal in Group 13 be more or less reactive that a metal in Group 1?
less reactive.beacuse group-1 elements are the most reactive elements.
What are the two highly reactive elements in period 4?
the metal potassium and the nonmetal bromine
Which of the elements in Group 1 are the most reactive?
it is caesium.
Are groups 1 and 2 more or less reactive in periodic table?
Group 1 elements are the most reactive among metals, followed by group 2 elements.
What common characteristic is generally shared by the elements at the center of a period?
Elements at the center of a period tend to have the highest electronegativity and smallest atomic radii compared to the other elements in the period. Additionally, these elements often possess a stable electron configuration.
What happens to the reactivity of elements in groups as the atomic numbers increase across a period?
they become more reactive since you are moving from left to right on the Periodic Table, the elements in group 17 are the most reactive.
Which periodic table family consists of highly-reactive elements?
S block has the most reactive elements. The groups 1 and 2 belongs to the s block.
What happens to reactivity of elements in groups labeled a as atomic numbers increase across a period?
they become more reactive since you are moving from left to right on the Periodic Table, the elements in group 17 are the most reactive.
Do group 1 metals contain reactive or unreactive elements and why?
Except hydrogen, elements in group 1 are very reactive at they can give away their only electron in their valence shell easily to be ionized.
