Learning Goal: This question reviews the format for writing an element's written symbol. Recall that written symbols have a particular format. Written symbols use a form like this: 35C1 In this form the mass number, 35, is a stacked superscript. The atomic number, 17, is a stacked subscript. "Cl" is the chemical symbol for the element chlorine. A general way to show this form is: mass number Symbol atomic number It is also correct to write symbols by leaving off the atomic number, as in the following form: 35Cl or mass number Symbol This is because if you write the element symbol, such as C1, you know the atomic number is 17 from that symbol. Remember that the atomic number, or number of protons in the nucleus, is what defines the element. Thus, if 17 protons are in the nucleus, the element can only be chlorine. Sometimes you will only see 35 C1, where the atomic number is not written. Watch this video to review the format for written symbols. In the following table each column…
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…
