Best Answer: An ionic radius, is the radius of an ion, either by gaining electrons or losing an electrons is considered to be an ion.n nonmetals, the ionic radii is larger than atomic radii, because non metals tend to gain electrons in the o uter shell. The electrons that it gained repel each other(because of same charge) so require more space, creating a greater radii. tmlfan Â· 9 years ago. Thumbs up.
Dynamite is an explosive made of nitroglycerin, sorbents (such as powdered shells or clay) and stabilizers. It was invented by the Swedish chemist and engineer Alfred Nobel in Geesthacht, and patented in 1867. It rapidly gained wide-scale use as a safer alternative to gun powder and nitroglycerin.
Wilhelm Conrad RÃ¶ntgen was a German mechanical engineer and physicist, who, on 8 November 1895, produced and detected electromagnetic radiation in a wavelength range known as X-rays or RÃ¶ntgen rays, an achievement that earned him the first Nobel Prize in Physics in 1901. In honour of his accomplishments, in 2004 the International Union of Pure and Applied Chemistry named element 111, roentgenium, a radioactive element with multiple unstable isotopes, after him.
