Is CR magnetic?
Chromium is remarkable for its magnetic properties: it is the only elemental solid which shows antiferromagnetic ordering at room temperature (and below). Above 38 °C, it transforms into a paramagnetic state.
What is SN on the periodic table?
tin (Sn), a chemical element belonging to the carbon family, Group 14 (IVa) of the periodic table. It is a soft, silvery white metal with a bluish tinge, known to the ancients in bronze, an alloy with copper. The symbol Sn for tin is an abbreviation of the Latin word for tin, stannum.
Is CR a metal?

What is full form for CR?
The full form of CR is Credit. The word credit has different meanings in the world of financial accounting as sometimes it can be referred to as a journal entry made on the right-hand side of an account representing a rise in assets and records all the income and revenues (in nominal accounts.
Is Cr a metal?
What is the oxidation state of Cr in Cr2O72?
Answer: The sum of the oxidation numbers in Cr2O72-, a polyatomic ion, is -2, the charge of the ion. There are seven oxygen atoms, so the total charge is − 2⋅7 = − 14. So, a chromium atom here has an oxidation number of + 6.
What does the symbol Cu mean on the periodic table?
Those are subtle reminders of the history of the Periodic Table and the process of the discovery of elements over the millennia. Eight of these oddities are Au (gold), Ag (silver), Cu (copper), FE (iron), SN (tin), Pb (lead), Sb (antimony), and Hg (mercury): All were among the elements recognized by the ancient Greeks and Romans, and the abbreviations for those are based on a Latin or Greek term for the element.
What are some interesting facts about the periodic table?
Interesting Facts About Periodic Table. Periodic Table is a table of the chemical elements arranged in order of atomic number, usually in rows, so that elements with similar atomic structure (and hence similar chemical properties) appear in vertical columns.
What are the 5 traditional elements?

What are the families on the periodic table?
Families on the periodic table include, in addition to noble gases and halogens, the alkali metals, alkaline earth metals, transition metals, lanthanides, and actinides. The nonmetals form a loosely defined cross-family grouping, as do the metalloids.
