Sodium And Potassium Reaction Lab
Results and discussion:
I.
a. How would you compare that relative reactivity of Na and k
-Sodium and potassium react somewhat similar when reacting with water however they are slightly different. Sodium moves because of the hydrogen coming off of it and has a low melting point while potassium’s reaction is faster and enough heat is produced to set light to the hydrogen coming off of it. Each leaves a pink color hue in the water.
Discuss the similarities and differences in the behavior of the metals tested with water relative to their positions in the periodic table. Compare behavior within a family and in the same period.
- The similarities and differences between the metals tested with water that are relative to their position in the periodic …show more content…
This in turn depends on how much the negative charge can be spread around the rest of the ion.
Discuss general trends in metallic and non- metallic properties as shown by the experiment.
- Metal ions and elements tend to form positive ions and like charges repel therefore they can migrate and the fluid mosaic allows them to move around the atomic radius is half the distance between the two adjacent nuclei of atoms in a metal lattice. Metallic properties also are very exothermic and vigorously when heated.
Conclusion:
The elements are arranges due to their atomic weight, exhibiting an evident stepwise variation of properties. Chemically analogous elements have similar atomic weights or increase by equal increments. Within the period each elemtens reacts differently with a solution that it could be put in. This is due to either what group or period it is in and periodic trends also affect this. Whether the element is metallic or non metallic the elements differ. Metallic elements have higher atomic weight and radius while non-metallic have high electronegativity and ionization trends. With each being so different we tested each element given and saw what happened when dropped into a certain solution to determine how periodic trends related to this
