WebAs you go down group 1 (the alkali metals) in the periodic table, the elements get more reactive. As you go up group 7 (the halogens), again the elements get more reactive. Is as follows: To remember how the reactivity of the alkali metals and halogens increases or decreases, put a pin in the middle of the periodic table and spin it anti-clockwise. WebAug 3, 2024 · As we go down group 1, the outer electrons become easier to lose and so the alkali metals become more reactive. Using trends to predict properties All elements in group 1 are known as the alkali metals. They all have one electron in their outer shell which they need to lose to achieve stability.

WebThe group 1 metals are known as the alkali metals. They form alkaline solutions when they react with water. The group 1 metals are lithium, sodium, potassium, rubidium, caesium and francium and they are found in the first column of the periodic table. The alkali metals share similar characteristic chemical properties because they each have one ... WebFor group 1, they become reactive when they can lose that electron. It is easier to lose it as the electron moves further away from the nucleus as the attraction is weaker. Therefore, … ready mix concrete new braunfels tx

WebJan 30, 2024 · As you go down a group, electronegativity decreases because the bonding pair of electrons is increasingly distant from the attraction of the nucleus. Consider the hydrogen fluoride and hydrogen chloride molecules: The bonding pair is shielded from the fluorine's nucleus only by the 1s 2 electrons. WebThere is no change in their reactivity going down the group.? They become more soluble in water as they go down the group.? They increase in order of reactivity. Why are the elements fluorine, chlorine and iodine placed in the same group of the Periodic Table?? They have the same number of electrons in their outer shell. ...
