Researchers from Lund University in Sweden created it by slamming atoms of one element, calcium, into atoms Scientists confirm new element 115 after atoms collide By Ben Brumfield (1) As though it wasn't hard enough to memorize the names and atomic weights of 117 elements in the periodic number of 115 on the periodic table, the list of all elements known to humanity. table, scientists have now confirmed a new one. of another called americium. . Use paragraph 1 and 2 to describe how the element with 115 protons was createc. (3)The Swedes were the second groun of scientists to create the element. A group of Russian scientists put together the same type of atom in 2004. (4)But the new experiment corroborated their work and confirmed 115's existence. Still, this doesn't mean that you'll see element 115 on the next periodic table poster that gets published. The discovery still has to be approved by a committee composed of members of the International Union of Pure and Applied Chemistry and…

Finding atomic mass from isotope mass and natural abundance A robot spacecraft returned samples from the planetesimal 98765 ALEKS, located in the outer Solar System. Mass-spectroscopic analysis produced the following data on the isotopes of tin in these samples: isotope 119 S Sn 118 Sn Sn mass relative (amu) abundance 118.9 93.3% Explanation 117.9 Use these measurements to complete the entry for tin in the Periodic Table that would be used on 98765 ALEKS. Be sure your answers have the correct number of significant digits. Caution: your correct answer will have the same format but not necessarily the same numbers as the entry for tin in the Periodic Table we use here on Earth. 6.7% X Check 3 ? O ol Ar ve Graw Hill LLC.
