The reactivity increases. Group 1 are the alkali metals so they react by losing their valence electrons. Caesium is more reactive because it gives up its ...

As you move down the group the number of electron shells increases, which as a result increases atomic radius. This is known as the shielding effect and as a ...

All group 1 metals have one electron in its outer shell. As we go down the group, the atom gets bigger. The bigger the atom, the further away the last electron.

Reactivity increases down the group. This is because the outer electron in each atom is further away from the nucleus as you go down the group.

As you go down the group, there are more inner electrons. These repel the outer shell electron (like charges repel) therefore pushing it away. This means that ...

As you go down the group, there is an additional electron shell added each time (1). These electron shells hold negativley charged electrons that shield the ...

The reactivity increases down the group from Mg to Ba. This is because the further away an electron is from the nucleus, the weaker its attraction.

As the number of electron shells increases down the group, and consequently the atomic radii get bigger, the attraction between the nuclei and outer shell ( ... Не найдено: reactivity | Нужно включить: reactivity

As you move down group 7 from fluorine to iodine, the reactivity of the elements decreases. The halogens are non-metals and when non-metals react with metals, ...

Le Chatelier's principle states, that when a system that is in equilibrium is subject to a change of concentration, volume, pressure or temperature, ...
