WebOct 6, 2007 · The answer lies in understanding what the atoms are trying to do. Group I metals are aiming to lose an electron from their outside shell. This can happen easiest if the electron is in a shell that is a long ay from the nucleus so that there is less attraction between the nucleus and the electron. WebReactivity increases down group 1 as the outer shell becomes further away from the nucleus so the electron is easily lost have lower melting and boiling points/higher RAM …

WebFor group 1 Alkali metals- this means that the lower down the group the less energy needed to remove an electron so the easier it is to form positive ions/ easier to react. Now what about group 7 - halogens. These atoms will want to gain an electron to form a negative ion with a full outer shell. four theories of dreaming

Why does the group 7 element become more darker as we move down the group?

WebApr 3, 2013 · As you go down any group, there are extra electron shells (for example Lithium has 2 shells, Francium has 7) which cause electron shielding.

They decrease in order of reactivity.? There is no change … WebTrends in atomic radius down a group. It is fairly obvious that the atoms get bigger as you go down groups. The reason is equally obvious - you are adding extra layers of electrons. ... As you add extra layers of electrons as you go down a group, the ions are bound to get bigger. The two tables below show this effect in Groups 1 and 7 ... four theories of aging
