The chemical reactivity increases as we go down the group for metals and decreases in the case of non metals

Reactivity generally increases down a group of atoms. This is because as you move down the group, the atomic radius increases and the valence electrons become further from the nucleus. As a result, the valence electrons are less strongly attracted to the nucleus, making them more easily available for bond formation and chemical reactions.

Does the reactivity of elements in group 2 increase going up or down?
The reactivity is increasing goinng down in the group.
What happens to the reactivity of a nonmetal when you move from left to right in a group?
The reactivity of a non metal decreases as you move down a group. This is because the size of the atomic radius increases and when the distance to the nucleus increases, the force of attraction decreases. Electrons are not pulled as strongly to larger atoms, and so larger atoms are not as reactive.
What happens to the reactivity of halogens as you go down the group?
the reactivity of halogens goes on decreasing as we go down the group, because of increasing in atomic size of the respective element.
Does halogens reactivity decreese as you mov down the group?
Nope.
Why does reactivity of the halogens decrease down the group?
As it go down the group, the distance between the nucleus (+ve) and the last electron (-ve) becomes smaller No: BIGGER.Therefore the electrons are held in the atom very tightly more loosely by a strong weakening force from the nucleus.So, it is said as the reactivityDEcreases down the group of NON-metals which gain stronger their electrons andINcreases down the group of metals which loose those electrons.
How does the reactivity of group 1 metals change as you go down group 1?
The reactivity increase down in the group.
How does the reactivity of halogens change as you go down group 7?
dno
Does the reactivity of elements in group 2 increase going up or down?
The reactivity is increasing goinng down in the group.
Alkali metal reactivity?
the reactivity increases as you go down the group
Among the alkali metals how does the tendency to react with other substances change within a group?
The chemical reactivity increase down in the group.
What happens to the reactivity as you move down group 1 in the periodic table?
Reactivity in group 1 of elements increases as we go down the group (to francium) because in the alkali metals as we go down the group number of atomic shells increases so the elements with most shells will easily release their electrons in the outer most shell.
How does reactivity work with the elements when you go down the groups?
Down the group, reactivity decreases for non metals. It increases for metals.
How does reactivity work with the elements going down the groups for metals and non metals?
Reactivity increases down the group for metals. It decreases down the group for non-metals.
What happens to the reactivity of a nonmetal when you move from left to right in a group?
The reactivity of a non metal decreases as you move down a group. This is because the size of the atomic radius increases and when the distance to the nucleus increases, the force of attraction decreases. Electrons are not pulled as strongly to larger atoms, and so larger atoms are not as reactive.
What happens to the reactivity of halogens as you go down the group?
the reactivity of halogens goes on decreasing as we go down the group, because of increasing in atomic size of the respective element.
Does halogens reactivity decreese as you mov down the group?
Nope.
What is the periodic trend for reactivity of metals?
Metals Period - reactivity decreases as you go from left to right across a period.Group - reactivity increases as you go down a group Why? The farther to the left and down the periodic chart you go, the easier it is for electrons to be given or taken away, resulting in higher reactivity.Non-metals Period - reactivity increases as you go from the left to the right across a period.Group - reactivity decreases as you go down the group. Why? The farther right and up you go on the periodic table, the higher the electronegativity, resulting in a more vigorous exchange of electron.
