CHEMISTRY OF CHOLESTEROL AND HEART DISEASES

Image
 CHEMISTRY AND HEART CHOLESTROL- SOURCE- WAVEMAGAZINEONLINE What do we know about cholesterol or what is cholesterol? Cholesterol is a waxy, fat-like substance that are needed to make some useful hormones and is found in our blood. Cholesterol is actually needed to build certain kind of cells, but the it's presence in large quantities can have harmful effects too. It comes from two sources, first, our liver makes cholesterol that we need, the other source is, it can be obtained from food which are derived from other animals. Now, there are two types of cholesterol- 1. LDL Cholesterol- LDL stands for "low-density lipoprotein". This type of parcel protein transports cholesterol from liver to rest of the body, high levels of LDL cholesterol leads to high chances of cardiovascular diseases. It is sometimes referred to as bad cholesterol. 2. HDL Cholesterol- "HDL" stands for "high-density lipoprotein". This type of protein transports cholesterol back to liv

Properties of FIRST FIVE ELEMENTS IN PERIODIC TABLE

FIRST FIVE ELEMENTS

We all are aware or might have heard about the names of 118 elements and the periodic table. We might know the positions of the elements in the periodic table but do we know some of the properties of these elements. Here I have tried to give you some of the properties of first five elements of the periodic table. They are as follows-

1) HYDROGEN

  • LATIN NUMBER- HYDROGENIUM
  • ENGLISH NAME- HYDROGEN
  • YEAR DISCOVERED- 1766
  • DISCOVERED BY- HENRY CAVENDISH
  • NUMBER OF ELECTRON- 1
  • NUMBER OF PROTONS- 1
  • NUMBER OF ELECTRONS- 0
Hydrogen is a chemical element of symbol- 'H' and has atomic number of 1. The atomic weight of hydrogen is 1.00794u, Hydrogen is the lightest element of the periodic table. It is the most abundant element in the universe. It is a monoatomic element.

2) HELIUM

  • LATIN NUMBER-     HELIUM
  • ENGLISH NAME- HELIUM
  • YEAR DISCOVERED- 1895
  • DISCOVERED BY- Pierre Jules Cesar Janssen, Joseph Norman Lockyer
  • NUMBER OF ELECTRON- 2
  • NUMBER OF PROTONS- 2
  • NUMBER OF ELECTRONS- 2
  • MELTING POINT- (-272.2℃)
  • BOILING POINT- (-268.9℃)
  • BLOCK- p-block

Helium is a chemical element of symbol- 'He' and has atomic number of 2. It is a colorless, odorless, tasteless, non-toxic, inert, monoatomic gas that occupies the topmost group of the noble gases. It's boiling and melting points are the lowest among all the elements. It's atomic weight is 4.0026(g/mole).

3) LITHIUM

  • LATIN NUMBER- LITHIUM
  • ENGLISH NAME- LITHIUM
  • YEAR DISCOVERED- 1817
  • DISCOVERED BY- Johan August Arfwedson
  • NUMBER OF ELECTRON- 3
  • NUMBER OF PROTONS- 3
  • NUMBER OF ELECTRONS- 4
  • MELTING POINT- (180.5℃)
  • BOILING POINT- (1342.0℃)
  • BLOCK- s-block

Lithium is a chemical element of symbol- 'Li' and has atomic number of 3. It is a soft silver-white metal belonging to alkali metal group.

4) BERYLLIUM

  • LATIN NUMBER- Beryllium
  • ENGLISH NAME- Beryllium
  • YEAR DISCOVERED- 1798
  • DISCOVERED BY- Louis-Nicolas Vauquelin
  • NUMBER OF ELECTRON- 4
  • NUMBER OF PROTONS- 4
  • NUMBER OF ELECTRONS- 5
  • MELTING POINT- (1278.0℃)
  • BOILING POINT- (2970.0℃)
  • BLOCK- s-block

Beryllium is a chemical element with symbol 'Be' and atomic number 4. It is a relatively rare element in the universe. It is created through stellar nucleosynthesis.

5) BORON

  • LATIN NUMBER- BORUM
  • ENGLISH NAME- BORON
  • YEAR DISCOVERED- 1808
  • DISCOVERED BY- Joseph Louis Gay-Lussac, Louis Jacques Thenard, Humphrey Davy
  • NUMBER OF ELECTRON- 5
  • NUMBER OF PROTONS- 5
  • NUMBER OF ELECTRONS- 6
  • MELTING POINT- (2075.8℃)
  • BOILING POINT- (3926.8℃)
  • BLOCK- p-block
Boron is a metalloid chemical element with symbol 'B' and atomic number 5. It is a low-abundant element both in solar system and earth's crust. It is formed by cosmic ray spallation and supernovae.

THANK YOU for reading. The properties of other elements will be uploaded soon and their will will also be dropped.
STAY TUNED :)

EIFFEL TOWER- POWER OF TRIANGLES

Image
 In this blog, you can learn how architects use mathematics, geometry, other math principles like surface area(might be your favourite), volume, ratios. GEOMETRY is used everywhere in the world. It can be found from artworks to mobiles, laptops and to the large structures, monuments and buildings. Shapes are the building blocks in architecture. Below are some examples of Mathematics being used in constructing the world!!   LETS START- EIFFEL TOWER(The Triangular Structure) PARIS, FRANCE TRIANGLES are the strongest shapes when it comes to building large structures. The triangles are the strongest shapes because of their ability to hold large strength without snapping. If all the three sides of triangle are made equal, then it will be able to distribute the whole weight equally in a large structure.   The tower is 1063 feet(30,000cm) tall and its construction cost 7,799,401 French Gold Francs(10 crores) in 1889.  We know the history of the tower that EIFFEL TOWER is situated in FRANCE

WHAT IS A GOOD FUEL?

Image
 GOOD FUELS WITHOUT AN END TO THE BURNING OF FOSSIL FUELS, COAL ESPECIALLY, MOST OF US WILL LIVE SHORTER LIVES. I AM HOPEFUL BUT VERY, VERY CONCERNED  All your questions like- Write it's properties to find whether it is clean fuel or not and  Some commercial uses of fuel, will be answered here, enjoy reading. Some terms before starting- CALORIFIC VALUE- The amount of heat produced by burning a unit mass of the fuel completely is known as its CALORIFIC VALUE. IGNITION TEMPERATURE- The minimum temperature to which a fuel must be heated so that it may catch fire and start burning, is known as IGNITION TEMPERATURE. The definition of a good fuel cannot be given in one line or sentence. There are various conditions that makes a fuel good. We also need to keep in mind that, by saying the term 'GOOD FUEL' we are comparing one fuel with another. None of the fuel can be the best, but can be better in comparison to another. CHARACTERSTICS OF A GOOD FUEL- HIGH CALORIFIC VALUE- A good f
