The ability to lose electrons increases down a group and right to left in a period. So potassium is more reactive than lithium because the outer electron of a potassium atom is further from its nucleus than the outer electron of a lithium atom. outermost electron is better. sodium can form Na+. shielded from the attractive force. It follows, therefore, that this outermost electron is more easily lost than it is in sodium, so potassium can form K+ more readily than sodium can form Na+. form K+ more readily than.

Similar Questions The effect of a given sound lasts on a human ear for about 0.1 second.Use this fact along with the knowledge of speed of sound to estimate for getting a clear and a distinct echo? sodium. The reactivity of group 1 elements increases as you go down the group because the atoms become larger; the outer electron becomes further from the nucleus; the force of attraction between the nucleus and the outer electron decreases; the outer electron is lost more … It follows, therefore, that this outermost. Log in. electron. Hence, potassium is more reactive than sodium. This is due to increase in atomic size and less nuclear charge.The atomic radius of potassium is bigger than sodium. Thus, in potassium, the outermost electron is better shielded from the attractive force of the nucleus. Metal 's reactivity depends on the ability to lose electrons. So potassium is more reactive than sodium and sodium is more reactive than lithium. Why potassium is more reactive than sodium . Answered Why is sodium is more reactive then potassium 2 See answers Why is sodium is more reactive then potassium - 17275171 1. Join now. Potassium is more reactive than sodium because it is larger in size and thus it is easier for it to remove its electron and react with other elements. Thus, in potassium, the. Hence, potassium is more reactive than. Log in. Therefore potassium is the most reactive … Why pottesium is more reactive than sodium - 21301241 aishwarya6373 is waiting for your help. of the nucleus. 2K(s) + 2H2O(l) → H2(g) + 2KOH(aq) Why is potassium more reactive than sodium? Outer electron of a potassium atom is furthest within these three metals from its nucleus than the outer electron of a sodium and lithium atom. it is in sodium, so potassium can. Like the other alkali metals, potassium reacts violently with water, producing hydrogen. The reaction is notably more violent than that of lithium or sodium with water, and is sufficiently exothermic that the evolved hydrogen gas ignites. 1.
