The given set of elements has to be classified as metal, non-metal, or metalloid. Concept Introduction: Substance that is a good conductor of electricity and heat, which has a shine or luster, is known as metal. Usually metals are solids at room temperature except for mercury. Metals are ductile and malleable. Non-metals are elements that do not possess the metallic characteristics. Non-metals are not shiny. They do not conduct electricity and heat except grapheme. Metalloids are the one which has both metallic and non-metallic properties. They are semimetals. Elements like Silicon and Germanium conduct electricity when temperature is increased. But at room temperature they are poor conductor of electricity.

The given set of elements has to be classified as metal, non-metal, or metalloid.
Concept Introduction:
Substance that is a good conductor of electricity and heat, which has a shine or luster, is known as metal. Usually metals are solids at room temperature except for mercury. Metals are ductile and malleable.
Non-metals are elements that do not possess the metallic characteristics. Non-metals are not shiny. They do not conduct electricity and heat except grapheme.
Metalloids are the one which has both metallic and non-metallic properties. They are semimetals. Elements like Silicon and Germanium conduct electricity when temperature is increased. But at room temperature they are poor conductor of electricity.
5. A buffer consists of 0.45 M NH, and 0.25 M NH-CI (PK of NH 474) Calculate the pH of the butter. Ans: 9.52
BAS
PH-9.26 +10g (10.95))
14-4.59
PH=4.52
6. To 500 ml of the buffer on #5 a 0.20 g of sample of NaOH was added
