Difference between metal and non metal in both chemical and physical properties |
| Answer» MetalsMajority elements are metals. This includes alkaline earth metals, alkali metals, transition metals, actinides, and lanthanides. Metals are separated by nonmetals on a periodic table through a zigzag line starting from carbon, phosphorus, selenium, iodine, and radon. These elements and elements right to them in the periodic table are nonmetals. Elements present just to the left of the line are termed as semi-metals and metalloids. These will have the combined properties of both metals and nonmetals.Physical properties of metalsShiny (lustrous)Good conductors of electricity and heatHigh densityHigh melting pointMalleableDuctile and so can be drawn into wiresSolid at room temperature except for mercuryOpaque objectsChemical properties of metalsEasily corrodibleCan lose electronsForm basic oxidesHave lower electronegativitiesActs as very good reducing agentsNonmetalsVery few elements in the periodic table are nonmetals. These are present on the right side of the periodic table. Elements that come under nonmetals are hydrogen, carbon, nitrogen, phosphorus, oxygen, sulfur, selenium, all the halogens, and the noble gases.Physical properties of non-metalsPoor conductors of electricity and heatNon-Ductile metalsBrittle solidsMay be solids, liquids or gases at room temperatureThese are not sonorousTransparentChemical properties of non-metalsGenerally, contain 4-8 electrons in the outer shellReadily lose or gain valence electronsForm acidic oxid | |

Why graphite is soft |
| Answer» Graphite: Carbon atoms are arranged in 2D sheets, whereas each carbon atom is bonded to three other carbon atoms to form hexagonal rings in an infinite array. Although the bonding of atoms within each individual layer is covalent and therefore quite strong (as strong as is seen in diamond), the bonding between layers is weak (Van der Waals forces). The result of this is that the layers slide over each and can detach from each other very easily. These weak bonds between the multiple sheets of carbon atoms make the graphite used in pencils flake off on paper, allowing you to write. In addition to being soft and slippery, graphite also has a much lower density than diamond. | |

What is translocation in plants |
| Answer» Translocation is the movement of materials from leaves to other tissues throughout the plant. Plants produce carbohydrates (sugars) in their leaves by photosynthesis, but nonphotosynthetic parts of the plant also require carbohydrates and other organic and nonorganic materials. For this reason, nutrients are translocated from sources (regions of excess carbohydrates, primarily mature leaves) to sinks (regions where the carbohydrate is needed).Some important sinks are roots, flowers, fruits, stems, and developing leaves. Leaves are particularly interesting in this regard because they are sinks when they are young and become sources later, when they are about half grown. | |
