As we go down the group, nuclear charge deceases and atomic radii increases. So the element can easily lose electron and hence react.
What else can I help you with?
Alkali metal reactivity?
the reactivity increases as you go down 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.
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.
How do you tell the reactiveness of a non metal on the periodic table?
The periodicity of nonmetals is that reactivity increases from left to right across a period, through group 17, the halogens. As you move down a group, reactivity decreases. Fluorine is the most reactive element.
How does the chemical reactivity to alkali metal vary?
As you move down the alkali metal group on the periodic table, chemical reactivity increases. This is because the outermost electron in alkali metals is easier to lose as you go down the group, resulting in more reactive behavior with water and air. Lithium is the least reactive alkali metal, while cesium is the most reactive.
How does reactivity change down the group of atoms?
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.
How do elements change going down the periodic table?
Down a group, the atomic number generally increases, size increases, ionization energy decreases, reactivity increases.
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.
Is lithium or cesium more vigorous in water?
Cesium is more reactive. Down the group reactivity increases.
What happens as you move down the family on a periodic table the reactivity?
the reactivity of metals increases as you go down a group in the periodic table. also elements in the same group have similar chemical properties because they have the same electronic configuration,i.e.they have the same arrangement of 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 reactivity work with the elements when you go down the groups?
Reactivity tends to decrease as you go down a group in the periodic table. This is because as you move down a group, the valence electrons are further from the nucleus and are shielded by more inner electron shells, making it harder for the outer electrons to participate in chemical reactions.
