In general, is there a relationship between the locations of metals on the Periodic Table and their relative activity? Explain why.Īs you move down a group (column) the elements get less reactive. That being said, I also thought about how calcium did at least something, while tin did absolutely nothing in HCL, meaning it probably won't do anything in water.ģ. I took into account that water is pretty much neutral, and nothing major will happen to any of these elements in water. Use data from your lab to support your answer. List the four metals from most reactive to lease reactive. Because of the difference, they will react differently.Ģ. Magnesium is a solid while calcium is a powder. What might be a reason for the difference in behavior between magnesium and calcium when placed in water? Record data and observations in the table below.ġ. Add enough water to cover the sample (use a disposable pipette).Ĥ. Get your samples from Charlene and put them in the labeled test tubes.ģ. Gather your supplies and label the test tubes.Ģ. Part one - trends in properties within groupsġ. What element is in Group three and Period three?Īluminum is in both group three and period three. Group one are the alkali metals, group two are the alkali earth metals.Ĥ. What are the names of two metal families? The metals are located to the left of the metalloid boundary.ģ. In general, where are the metals located on the periodic table? Families are specific groups on the periodic table.Ģ. What are groups? What are periods? What are families? The elements on the left tend to be more reactive and the elements on the right tend to be less reactive.Ĩ.) Arrange each of the following metals in order from most to least reactive.To explore the reactivity trends of metals in groups and periods of the periodic table.ġ. As you move higher up a column, the elements tend to be more reactive.ħ.) What can you conclude about the reactivity of metals as you move across a period? Some trends I learned from these labs are that, starting from left to right, the elements on the left are more reactive and the elements on the right are less reactive.Ħ.) What can you conclude about the reactivity of metals as you move down a column or group in the periodic table? Describe some of the trends that you learned about from this lab? based on this trend, what do you estimate the density of silicon to be?ĥ.) When elements are organized in the periodic table, various trends appear. The density of tin is about 7.28g/cm ³ and the density of Pb is 11.34 g/cm ³. Elements in the periods near the top of the periodic table tend to react more, while those close to the metalloid boundary and in the bottom left do not react as much.Ĥ.) Silicon, tin, and lead are all in the same group. Use data from your lab to support your answer.ģ.) In general, is there a relationship between the locations of metals on the periodic table and their relative activity? Also, magnesium and calcium are in different periods on the periodic table, which may indicate that they react differently.Ģ.) List the four metals from most reactive to least reactive. The difference in behavior might have been because magnesium was in a solid form and the calcium was dehydrated and powdered, which appeared to mix with the water easily and dissolve. Wash test tubes.ġ.) What might be a reason for the difference in behavior between magnesium and calcium placed in water? Procedure - Part 1: Trends in Properties Within GroupsĤ.) Fill a beaker with tap water and get a disposable pipette.ĥ.) Bring test tubes to Charlene to get a sample of magnesium and a sample of calcium.Ħ.) Use pipette to cover sample with water.ħ.) Observe reaction carefully and enter data in table.Ĩ.) Dump sample into hand in sink, rinse sample, and place in corresponding labeled beaker. Gallium is in Group 3 and the 3rd period. The alkali metals are the first group on the periodic table and the alkali earth metals are the second group.Ĥ.) What element is in Group 3 and the 3rd Period? The metals are located to the left of the metalloid boundary.ģ.) What are the names of two metal families? The groups of the periodic table that share a lot of similarities with all of the other elements in that group are called families.Ģ.) In general, where are the metals located on the periodic table? The periods of the periodic table are the horizontal rows. Groups of the periodic table are the vertical columns. To explore the reactivity trends of metals in groups and periods of the periodic table.ġ.) What are groups? What are periods? What are families?
