Why are Helium, Curium and Barium considered healing elements. Because if you cant Curium (cure them) or Helium (heal them) you then must Barium (bury them).
I would say more periodic table jokes but all the good ones argon (are gone).
Researchers at the University of Adelaide have created what was once science fiction, into reality. Tractor beams are these powerful beams of invisible infrared light, despite what you see in movies, that trap atoms to the more intensified areas of light in the beams. This proves useful for optical fibres, as atoms will get sucked into the fibre by the tractor beams (logically anything can become a black hole, just requiring an intense amount of heat energy congregated into one area) and the atoms will stay there for a long time.
Scientists gathered at a symposium question the accuracy of assessing the four new elements that were added to the periodic table, connected to tension in the chemistry and physics communities.
According to this article ionic compounds have a higher melting temperature than covalent because the ionic compounds have a stronger bond due to the fact that negative and positive charges objects (or ions) attract. Covalent ions will share electrons which will still create a bond between atoms/molecules however since the atoms share the electrons it is easier for one electron to steal the electron and therefore takes less energy.
This image is funny because somebody asks if anybody knows any jokes about sodium hypobormite and the person responds with NaBrO. NaBrO is the formula for sodium hypobromite.
This is funny because "Ar (Argon)" sounds like "are gone".
This article introduces Dawn Shaughnessy, a nuclear chemist who recently aided in discovering new elements of the periodic table. These elements include nihonium, moscovium, tennessine and oganesson.
On the side, the article also details how American and Russian scientists have worked together over the past 30 years, despite politics and tensions between the countries.
"First Picture of an Atom's Shadow - Smallest Ever Photographed"
In the article, it talks about the first picture of an atom (element ytterbium) taken in a vacuum chamber, having shot a laser beam at the atom. The atom absorbed an insignificant portion of the light, but resulted in a shadow that was magnified by a lens and then recorded by a digital camera sensor.
Each element responds differently to different wavelengths, and will be continued to be researched, testing with different atoms and different laser systems using this technique.
The article also discusses the potential of this research, such as encrypting certain pieces of information into the DNA of atoms, which techniques currently harm cells of which they've attached special molecules to.
Chapter 6 talks about early atomic models and makes mention of scientists like; J.J Thompson,James Chadwick,Ernest Rutherford etc. It talks about the discovery of electron clouds and neutrons, as well as the atomic theory of matter by John Dalton
This article highlights some of the chemists who added six new elements to the periodic table. When the periodic table was first coming about, some chemists created elements mostly by accident. Today we know that the amount of protons determines the element's identity. In order for new elements to be created scientists have to figure out ways to get more protons in the nucleus. This American team decided on chemical reactions and the more theoretical background. This information is then sent to Russia where they have appropriate labs to test it. The six elements this team discovered were nihonium, (named for Japan), moscovium (Moscow), tennessine (Tennessee) oganesson ( Yuri Oganessian) and flerovium ( Flyorov)
When a metal and a non metal bond, the ions give or take electrons to make the total charge zero. This means that the number of ions on either side to make the bonding happen may vary. E.g. Sodium having a positive charge of 1, and Chlorine having a negative charge of 1, the Sodium ion gives the electron to the Chlorine, and now they have bonded, forming Sodium Chloride. This is ionic bonding. (The metal ends up positive, and the non metal is now negative)
This article talked about a woman alchemist, Dawn Shaughnessy whose team was partially responsible for adding 6 new elements on the periodic table. One of them was created by her team by turning plutonium into flerovium. The article also talked about how she would send very high energy elements such as uranium to Russia where scientists who operated a particle accelerator would hit the target with a beam of lighter elements. This would result in atoms flying out. A detector was used to measure how these elements lose their subatomic particles to radioactivity.
Write something about yourself. No need to be fancy, just an overview.
