does reactivity increase down a group for metals

#DOES REACTIVITY INCREASE DOWN A GROUP FOR METALS FULL#

To show that this is the case, I have drawn the shells for lithium and rubidium. This weaker force of attraction means that less energy is required to remove the electron on the outmost shell of a further down group 1 element, which results in the reactivities increasing as we go down the group 1 column. This means that there is a weaker force of attraction between the positively charged nucleus and the electron that further down group 1 elements are trying to lose. The reactivity increases as we go down the group 1 column because the single electron that a lower down group 1 element wants to lose is on an electron shell that is further away from the positively charged nucleus. For example, lithium is the least reactive, then sodium, potassium, rubidium, caesium and francium is the most reactive. The reactivity of the group 1 elements increases as we go down the group 1 column.

Group 1 elements are very reactive because they only have to lose one electron to obtain a full outer shell of electrons and become stable. The group 1 elements will become 1+ ions (Li +, Na +, K + etc). This results in the group 1 metal becoming positively charged as it has given/ lost an electron, and the non-metal becoming negatively charged as it has gained an electron. The reaction between a group 1 metal and a non-metal works by the group 1 metal giving one electron to the non-metal. The ionic compounds that are formed are usually white and they dissolve in water to form a colourless solution. They lose this single electron by reacting with a non-metal to form ionic compounds. Group 1 elements have one electron in their outermost electron shell, which they will want to lose so that they have a full outer shell of electrons. They have low melting and boiling points for metals, a low density and are very soft (they can be cut with a knife).

The elements in group 1 all have similar properties.
