hydroxide RESEARCH QUESTION How does the heat released during the reaction between distilled water and Group 1 elements (lithium‚ sodium and potassium) vary as one goes down the group? OBJECTIVE The objective of the experiment is to measure the heat change during the reactions with minimal heat loss to the surroundings. MATERIALS The materials to be used in this experiment are: • Lithium‚ sodium‚ and potassium metal are the three Group 1 elements and reactants. • Distilled water is a reactant. • 250ml

Table are those in which the last electron enters the outermost s-orbital. As the s-orbital can accommodate only two electrons‚ two groups (1 & 2) belong to the s-block of the Periodic Table. Group 1 of the Periodic Table consists of the elements: lithium‚ sodium‚ potassium‚ rubidium‚ caesium and francium. They are collectively known as the alkali metals. These are so called because they form hydroxides on reaction with water which are strongly alkaline in nature. The elements of Group 2 include beryllium

Bunsen burner‚ named after "Robert Bunsen"‚ is a lab piece equipment that produces a single flame which is used for heating‚sterilization and combustion. Our instructor‚ Dr. Immel‚ provided us with six heavy metals those metals were: Barium‚ Calcium‚ Lithium‚ Potassium‚ Sodium‚ Strontium. My group got a platinum flame loop‚ and decontaminated it with the water beaker filled half way with water. To light the Bunsen burner my group used a striker‚ which Dr. Immel provided. We started off with Barium‚ when

Yongnuo‚ a lithium-ion flash for Canon Canon warns photographers to never use lithium batteries in its flashes‚ but Yongnuo introduced a flash‚ Canon compatible‚ that uses a lithium-ion battery. The Yongnuo Speedlite YN686EX-RT is compatible with Canon’s RT- series of flashes‚ but contrary to Canon’s units uses a lithium-ion battery said to be faster and offer 750 full-power flashes from a single charge. When lithium batteries became a common thing in the market‚ some photographers managed to fry
