Carbon

In this post , Carbon information & the role of carbon in our life is well-known displayed..

Carbon :- Carbon is an important element which is mostly available & abundant in nature and occurs in combined state .

1) Symbol of Carbon :- C .
2)  Atomic Number (Z) :-  6 .
3)  Atomic mass (A) :-  12 .
4)  Valency :-  4 .
5)  Electronic Configuration :- 2 , 4 
      1s², 2s², 2p².
6)  Carbon is a Non-metallic element.

The name 'Carbon' is derived from the Latin word Carbo means coal.
Carbon is found in nature in free state as well as in compound state.

Carbon is found as diamond , graphite & fullerene .

1)  As carbon-dioxide and in form of carbonates such as calcium carbonate (CaCO³) , marble , calamite (ZnCO³) .

2)  Fossil Fuel - Coal , petroleum , natural gas .

3)  Carbonaceous nutrients - carbohydrates , proteins , fats .

4) Natural Fibres - Cotton , wool , silk .

Properties of carbon 

Allotrope nature of Carbon

Allotropy - Some elements occur in nature in more than one form . The chemical properties of these different forms are the same but their physical properties are different . This property of elements is called allotropy . Like carbon , sulphur , and phosphorous also exhibits allotropy .

⚫ Crystalline forms 

1)  A crystalline form has a regular and definite arrangement of atoms.
2)  They have high melting points and boiling points .
3)  A crystalline form has a definite geometrical shape , sharp edges and plane surfaces.

             ✊    Acupressure Points  👊 Our Body is full of a Complex System in that we have muscles , bones , blood and nerves , tissues . Our internal body parts are involuntary , and our external body parts are voluntary . We can't do exercise of our internal organs like brain , heart , liver , stomach , lungs , throats , hormonal glands and most of the internal organs . So we can do exercise by the connection of the nervous system by acupuncture the hands and legs and many other external parts . See this image for exercising internal organs  :-  By Acupuncturing all of the whole hand our internal exercise will be well done going on . Please do this for healthy health ....👍

Co-ordination in Plants

      🌳    Co-ordination in Plants   🌳 Plants do not have systems like the nervous system or muscular system of animals .  Then , how do plants bring about movements ?  In plants , movements are mainly in the form of responses given to the stimuli . Movement or growth of any part of the plant in response to an external stimulus is called 'tropism' or 'tropic movements' . The shoot system of any plant responds to the light stimulus that is it grows towards the source of the light . The movements shown by plants towards the source of the light is called 'Phototropic Movement' . The root system of plants responds to stimuli like gravitation and water .  These responses are called 'gravitropic movements' and 'hydrotropic movement' resectively . Movement shown by plants in response to specific chemicals is called 'chemotropic movements' .  For example , the growth of the pollen tube towards the ovule . All the above - menti...

Sonography

Sonography   What is Sonography ?  Sonography technology uses ultrasonic sound waves to generate images of internal organs of human body . This is useful in finding out the cause of swelling , infection , pain , etc . The condition of the heart , the state of the heart after a heart a heart attack as well as the growth of foetus inside the womb of a pregnant women are studied using this technique . This technique makes use of a probe and a gel . The gel is used to make proper contact between the skin and the probe so that the full capacity of the ultrasonic sound can be utilized . The gel is perfectly applied to the skin outside the internal organ to be studied . High frequency ultrasonic sound is transmitted inside the body with the help of the probe . The sound reflected from the internal organ is again collected by the probe and fed to a computer which generates the images of the internal organ . As , this method is painless , it is increasingly u...
