The number of possible elements is not known. A very early suggestion made by Elliot Adams in 1911, and based on the arrangement of elements in each horizontal periodic table row, was that elements of atomic weight greater than 256Â± (which would equate to between elements 99 and 100 in modern-day terms) did not exist.
IRS debts can only legally be collected for 10 years, but there are many events that may stop that 10 year clock from running. This is known as tolling the statute of limitations. Events that stop or toll the statute of limitations from running include:
One of the most common questions around tax refunds is how far back can a claim be made with HMRC, (formerly Inland Revenue), when making a claim. The time frame around claiming tax back used to be up to 6 years, however HMRC have now changed this to just 4 years. This year (2011) you can make a claim and if eligible receive a tax rebate for tax years 2010/11, 2009/10, 2008/09 and 2006/7. You would not be able to reclaim any overpaid taxes for any period before 5th April 2007. Interestingly HMRC can still go back up to 6 years or even up to 20 years, if you have not paid enough tax!
