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.
In 1879, Albert Einstein was born in Ulm, Germany. He completed his Ph.D. at the University of Zurich by 1909. His 1905 paper explaining the photoelectric effect, the basis of electronics, earned him the Nobel Prize in 1921. His first paper on Special Relativity Theory, also published in 1905, changed the world.
