How can we find period no. from the modern periodic table? |
| Answer» The period of an element corresponds to the principal quantum number of the valence shell. The block of an element corresponds to the type of orbital which receive the last electron.Example: Predict the period number atomic number 29.The period of the element = No. of principal quantum number of the valence shell = 4th | |

Series connection and parallel connectin |
| Answer» a series circuit with multiple points of load (like multiple light bulbs) will share the voltage given from the supply evenly (assuming the resistance of each bulb is the same)… however the current will remain the same accross the entire circuit.-a parallel circuit in the same sinareo will split the current evenly across all paths (assuming the resistance accross each path is the same) … however the voltage across the entire circuit and all paths will be same as supply.-measuring resistance total in a series circuit is as simple as adding them all together.-measuring all resistance total in a parallel circuit can be calculated using;1/Rt = 1/R1 + 1/R2…. Etc etc | |

What is mean of geothermal? And Geothermal energy. |
| Answer» Geothermal energy is generated at the geothermal power plants where the heat of earth is used to generate electricity. Due to some geological changes, the molten rocks present in the core of the earth are pushed to the earth’s crust. Steam is generated when the underground water comes in contact with these points forming hot springs. This trapped steam is used to generate electricity in the geothermal power plants. | |

Hydrogen is a non metal why we take it in reactivity series |
| Answer» Though hydrogen is not a metal but even then it has been assigned a place in the activity series. The reason is that like metals, hydrogen also has a tendency to lose electron and forms a positive ion H+. The metals which lose electrons less readily than hydrogen are placed below it and the metals which lose electrons more readily than hydrogen are placed above it in the reactivity series of metals. | |

Give 3 example of compound having ionic bonding? |
| Answer» An ionic bond is a type of chemical bond that has formed as a result of the complete transfer of valence electrons from one molecule to another. Metals will transfer their valence electrons to non-metals forming a positively-charged ions. The atoms that accept the electrons become negatively-charged. The two opposite charges will be attracted towards each other and form an ionic bond. Many compounds in the world are formed by ionic bonds and are therefore ionic compounds. Different types of salts are ionic compounds.Examples of Ionic Bonds:1. Sodium chloride - NaCl - table salt2. Calcium chloride - CaCl2 – rock salt3. Sodium hydroxide - NaOH - Lye used in soap4. Sodium fluoride - NaF – fluoride in toothpaste5. Iron Oxide – Fe2O3 - rust6. Calcium hydroxide – Ca(OH)2 – basic salt in antacid tablets | |

The left kidney is situated slightly lower than right kidney . Give reason |
|
Answer» Yogita ingle it ia situated to accomodate pancreas not liver The right kidney is placed at a slightly lower level than the left kidney in order to accommodate the largest gland/organ of the body, the liver. The liver bulges out on the right side of the body and then, tapers off to the left. Since, the abdominal cavity is limited in space, the body has been designed by nature to accommodate a large part of the liver by placing the right kidney at a slightly lower level as compared to the left kidney.\xa0 |

How magnetism is used in medecines? |
| Answer» In the field of medical science magnet has many uses like in:1. Pain Relief: Increased blood flow in magnetic field delivers more oxygen and natural painkillers called endorphins, which in turn relieves minor pain.2. Anti-Inflammatory: In presence of magnetic field, the increased blood circulation can reduce inflammation. When inflammation decreases, the body can also heal more quickly.3. Detoxification: Magnets can be used to divert the positive charges of various toxins created by the body\'s immune system when fighting infection to the liver for speedy detoxification and eventual elimination from the body through the kidneys. | |
