2. The reactivity of the metal increases with each period it goes down. Magnesium is the least reactive and is in the third period with an atomic number of 12. Calcium is slightly more reactive being in the fourth period and having an atomic number of 20. Barium is the most reactive because it is in the sixth period and it has an atomic number of 56. So the farther down in the group they go the more reactive they are.…
This experiment tested the theory that the elements in the periodic table are arranged in a manner in which the elements of a group share similar chemical properties. The elements we used were the ones from the alkaline earth metal group. These elements tend to form 2+ cations and are very reactive. We also compared these elements to that of lead because lead also forms a 2+ cation. We used the chemical property of solubility to observe the periodic trends of the alkaline earth metals. As a general rule, reactivity increases as you move down a group in the periodic table. This means in regards to solubility that the more you farther you move down the group the more insoluble the element is when combined with hydroxides, chlorides, bromides, iodides, sulfates, carbonates, and oxalates. My results were consistent with this theory in that the mixtures went from no reaction to forming a precipitate or from forming a light precipitate to a heavy one as the elements moved down the periodic…
The main purpose for this experimental lab is to determine the atomic weight of magnesium, as well as an underlying purpose in determining the relationship between moles evolved and consumed.…
What is Magnesium chloride(MgCl2)? What is it used for and why? What does it look like? Magnesium chloride is the name of a chemical formula of MG CL two. This is a salt and they are a typical ion halide. halides are very soluble to water. magnesium chloride is used for deicing on highways in sidewalks and also parking lots it is a good source of de-icing. The color that it appears is white or colorless crystalline solid. What is magnesium or what is chloride? whare are they located?…
INTRODUCTION For this experiment we studied an oxidation-reduction reaction of magnesium and hydrochloric acid solution. We compared the experimental measured amount of a product and the amount predicted by the theoretical calculation of a balanced equation: Mg (s) + 2HCl (aq) → MgCl2 (aq) + H2 (g) PROCEDURE First we obtained a strip of pre-cut magnesium ribbon, cleaned it with steel wool to remove any signs of oxidation from the strip (which would alter our results), and then weighed it (individual masses of the magnesium strips for each trial can be found in Table I below). We filled a large beaker more than half way full with warm tap water. We allowed the water to sit for a while to bring it to room temperature. While the water equalized, we obtained a 100ml-graduated cylinder and filled it with tap water (also at room temperature), and created with a lid of plastic wrap. It was important when creating this lid that no air bubbles formed under the lid. Then we inverted the graduated cylinder in the beaker full of water and carefully removed the lid. We folded up our magnesium ribbon and wrapped it with a short piece of copper wire so the magnesium would react and not break off during the reaction. We put this magnesium piece at the bottom of the beaker underneath the graduated cylinder. Using a thistle tube we gently propped the end of the tube up under the inverted graduated cylinder and then poured 10ml HCl into it. As the magnesium began to react, we slowly pulled the tube out and waited as the gas bubbles began to displace the water in the cylinder. After all the magnesium was consumed, we moved the graduated cylinder up and down in the water to equalize the water levels. Once we had accomplished this we took a reading of the amount of gas collected in the cylinder. We repeated this two more times.…
An elements¡¦ reaction to certain substances may be predicted by its placement on the Periodic Table of Elements. Across a period, an element on the left will react with more vigor than one on the right, of the same period. Vertically, as elements are sectioned into groups, the reaction of each element increases as you move down in the same group. With this in mind, the reactions of the substances involved in this experiment may be hypothesized, observed, and validated.…
An element or compound’s reactivity is its ability or capacity to react, or bond, with another substance. As you continue through this course, you will observe and compare this particular chemical property in a variety of scenarios.…

Abstract: The purpose of this lab was to see how magnesium reacts with oxygen. This reaction must be forced with heat. As magnesium changes to magnesium oxide the mass increased.…
The objective of this experiment was to observe evidence of a reaction and to determine the chemical equation, if there is a reaction. In order for a reaction to occur, a metal strip must have evidence of black or grey deposits on the surface of the metal once dipped into the solution. The reactivity of an element is related to its tendency to lose or gain electrons. Three metal strips that were used are copper, lead and zinc as well as the solutions of silver nitrate, copper(II) nitrate, lead(II) nitrate, magnesium sulfate and dilute(3M) sulfuric acid. The copper metal strip was placed in the silver nitrate and dilute(3M) sulfuric acid, the lead metal strip was placed in the copper(II) nitrate and the zinc metal strip was placed in the lead(II) nitrate, magnesium sulfate and dilute(3M) sulfuric acid. Overall, putting these different strips of metal into different solutions will help determine the reactivity of copper, lead, zinc, magnesium, silver and hydrogen.…

I will say it is easy to Magnesium preciously because Magnesium is containing so many foods that we eat every day. The foods that composed or rich magnesium are Spinach. Chard, Pumpkin Seeds among others. It can be said in terms of the percentage foods that contain magnesium Spinach 1 cup : 157 Milligrams ( 40% DV), Chard 1 cup 154 milligrams(38% DV). And black beans ½ cup : 60 milligrams (15% DV) . The best of my knowledge magniusm is found mainly in the foods we consume daily special…
As you go across each period of the Periodic Table of Elements, the reactivity of elements gradually decreases, as the atomic mass increases. The fewer valence electrons an atom holds, the less stable it becomes and the more likely it is to react, which is why elements in the beginning are more reactive.…
