Isotopes, Isobars and Isotones

Isotopes



  • These are elements which have the same atomic number but different atomic mass.
  • They have the same atomic number because the number of protons that are inside their nuclei remains the same.
  • But, they have different atomic mass because the number of neutrons that are also inside their nuclei is different.
  • As the number of protons inside nuclei remains same, therefore the overall charge of the elements also remains same as in isotopes: no of protons = no of electrons.
  • Hence, as isotopes overall charge remains neutral, therefore their chemical properties will also remain identical. 
Therefore, Isotopes are chemically same but physically different.

Examples of isotopes are:
1) Isotopes of hydrogen  
2) Isotopes of carbon 

Isobars 


  • These are elements which have same atomic mass but a different atomic number.
  • Hence, as isobars have different atomic number, therefore, they have a different number of electrons, and their chemical properties are different.
  • The light nuclei have unstable isobars.
  • Heavy nuclei have stable isobars and these occur in pairs.
  • If the number of protons of one isobar matches with that of another, then they are called as mirror-nuclides of each other

Therefore,  Isobars are chemically different but physically same.

examples:

Isotones


These are elements having the same number of neutrons.

Cathode Ray Experiment

This experiment was conducted by J.J. Thomson (Sir Joseph John Thomson) in the year 1897. This experiment proved that atom is made up of fundamental particles which are much smaller than the smallest atom 'hydrogen' This experiment helped to discover electron. According to J.J. Thomson, the cathode rays consisted of very light, small and negatively charged particles. He named the particles "corpuscles" which were later known as electrons

Android Versions Named After Sweet

Have you ever thought why are Android versions always named after sweet names ?? Everytime a new Android version is launched its name is kept after a sweet name. Many people have researched about this topic and many have asked Google also. Have you ever tried to find out the core reason behind this? If not then you would find the answer here . First of all let us first see what Google says about this : In 2008 i.e. the year when Android was launched a reporter asked the reason for the same. At that time Google said “It’s kind of like an internal team thing, and we prefer to be a little bit — how should I say — a bit inscrutable in the matter, I’ll say,” said Randall Sarafa, a Google spokesman. “The obvious thing is that, yeah, the Android platform releases, they go by dessert names and by alphabetical order for the most part."

Anode Ray Experiment

→Anode ray experiment was conducted by E Goldstein. →These rays are also known as canal rays. →This experiment helped in the discovery of the proton. Apparatus Used A discharge tube  was taken in which there were 2 electrodes i.e. Anode(+ve) and the cathode (-ve). The tube was filled with an inert gas. A perforated or porous cathode was used. A layer of zinc sulphide was placed at the back of the cathode. There was a vacuum pump in the tube. High voltage (5000v-10000v) was allowed to flow through the system. It was observed that when the gas was at 1atm(atmospheric pressure ) no change was seen in the tube.  When the   pressure   was decreased inside the tube, a glow could be seen at the back side of the cathode.

Rutherford Alpha Ray Scattering Experiment

Rutherford Alpha Ray Scattering Experiment Hey, Guys, most of you might have heard about the alpha ray scattering experiment and if you want to know in detail about Rutherford's model and the experiment he conducted, this is the right place for you... But first: Things You Must Know Some basic information that will help you understand rutherford experiment properly: Proton is a sub-atomic particle which is positively charged and has a mass of 1u. Alpha particles are helium atom with a charge of +2 as they have lost 2 electrons. Alpha particles have an atomic mass  of 4u. Gold is highly malleable and can be beaten into very thin sheets. Experiment Rutherford conducted his experiment in the following way: Rutherford took a very thin gold foil and bombarded it with high energy alpha particles. He placed a layer of zinc sulphide on the walls where the experiment was taking place because when alpha particles strike zinc sulphide layer, it results i

Animal and Plant Cells

 Cells Cells are the basic functional, biological and structural unit of life. The word cell is a Latin word meaning ‘small room’. Cells are also known as building blocks of life.  The branch of science that deals with the form, structure, and composition of a cell is known as Cytology. All organisms around us are made up of cells. Bacteria, ameba, paramecium, algae, fungi, plants and animals are made up of cells.  Cells together form tissues. And tissue together makes an organ. History Of Cell The cell was discovered by Robert Hooke in 1665. He assembled a simple microscope and observed a very thin slice of cork under his primitive microscope. The cork was obtained from the outer covering of a tree called bark. Robert Hooke observed many little-partitioned boxes or compartments in the cork slice. These boxes appeared like a honey-comb. He termed these boxes as the cell. He also noticed that one box was separated from another by a wall. What Ho

Sectors of Indian Economy

Hey there all the tenthees. You guys must be facing a lot of pressure as it is a board class as quoted by many teachers. You need to take care of each and every stuff including the small stats too. But unfortunately most of the Economics books we got do not have the graph 3 for the chapter Sectors of Indian Economy. No worries guys you came to the right place. We are providing you with the graph of December 2015 edition which is the latest graph which we need. All the best for your board exams and here you go Once again All the very best guys !!!

Doppler Effect

Doppler Effect states that there is a change in the frequency of sound because of the relative motion between the observer or the listener and the source of the object. In simpler words when the source and the listener are in a relative motion there is a change in the frequency of sound and this effect of a change in frequency is known as the Doppler's Effect of sound. When the objects move apart the frequency decreases. When the objects move towards each other the frequency increases. The change in the frequency of the sound is given by the formula:
