0.7. 2. General physical properties of Group 1 elements: Alkali metals are grey solids with shiny silvery surfaces when freshly cut. These surfaces turn dull when exposed to air. This is because alkali metals are very reactive. They react rapidly with oxygen and water vapour in the air when exposed.

These demonstrations show the similarity of the physical and chemical properties of the alkali metals and the trend in reactivity down group 1 of the Periodic Table. The experiments take about 10-20 minutes if everything is prepared in advance. Advance preparation includes cutting pieces of alkali metals to the recommended size, filling water ...

Procedure: Place about 1 cm depth of ammonium chloride in a small tube and add about 1 mL of 3 mol·L -1 sodium hydroxide solution (bench reagent). Stir. Warm the solution in a hot water bath. Report: (a) Note the odor. (b) Test the gas released with damp red and blue litmus paper.

For this part of the experiment you will make a graph of a periodic property vs. atomic number. The property chosen is atomic radius, given in pm (1 pm = 10-12m). The atomic radius, r, is related to the volume of the atom by the formula of a sphere, V = 4/3 r3. In Table 1 below, the atomic radii of the first 54 elements are given.

.All this justifies why the study of hydrogen is separated from the study of other Group 1 elements. 6.8.1. Properties of hydrogen atom. Hydrogen is the first element in the periodic table. It is the simplest and smallest element of the chemical elements.

form of ions, not as the neutral elements. All Group 2A elements react readily to lose two electrons and form ions with a +2 charge. All of the halogens readily gain one extra electron to form ions with a -1 charge. In Part 1 of the experiment, some properties of the Group 2A cations Mg 2+, Ca , Sr , and Ba2+ will be observed and compared. In ...

Key learning points. Group 1 elements are very reactive and their reactivity increases down the group. Moving down Group 1 elements, atomic mass, density and melting points increase. In chemical reactions, atoms of Group 1 elements lose one outer electron leaving full electron shells. Going down Group 1, the outer electron of each element is ...

Experiment 10 will illustrate the periodic table and periodicity. Remember, the lab may change or be modified from semester to semester! Experiment 10 is broken up into five main parts - A. Physical Properties, B. Oxides and Hydroxides of the Elements, C. Reactivity of a Metal Group, D. Reactivity Across a Period, and E. Reactivity of a Non ...

In section D, we observe the chemical properties of halogens such as chlorine, bromine and iodine, and we found the chemical reactivity of those. halogens. In section E, we study the chemical activities of the halides with metal ions. Lastly, we do some experiment to determine the reactivity of different elements in section F.

The properties of elements in each group in the periodic table change gradually down the group. Group 1 metals are all soft metals with lower densities than other metals, and become more reactive down the group. Group 1 metals react with water to form an alkaline solution and hydrogen, which is why they are called alkali metals. Group 2 metals ...

As shown in the diagram on the right, elements in this group are lithium, sodium, potassium, rubidium, caesium and francium. They are the first element of a period, with one valence electron. This similarity (1 valence electron) makes them chemically behave in a similar manner. All alkali metals are very reactive.

e concept of elements.Have students. read the introduction. Write the list of elements they will investigate in the activity on the board (aluminum, carbon, copper, germanium, iron, mercury, nitrogen, and sulfur). Ask students if they know of any other elements, and. add those to the list. If students name compounds, make a separate list to ...

Group 1 Metals + Oxygen Gas → Metal Oxide. Lithium, sodium and potassium form white oxide powders after reacting with oxygen. The white powder is the oxide of lithium, sodium and potassium. When the white powder is dissolved in water, it produces a solution which turned red litmus paper blue. Which means, these oxides dissolve in water to ...
