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:
The good news is that the IRS does not require you to go back 20 years, or even 10 years, on your unfiled tax returns. In most cases, the IRS requires you to go back and file your last six years of tax returns to get in their good graces. And then, to make arrangements on payment of what is owed. Thatâs right, a fairly reasonable and more manageable six years and working with IRS collections on payment options. The six year enforcement period for delinquent returns is found in IRS Policy Statement 5-133 and Internal Revenue Manual 1.2.14.1.18. Part of the reason the IRS requires six years is manpower â the IRS cannot administer and staff the enforcement of unfiled tax returns going back as far as 10 or 20 years. And believe it or not, the IRSâs records rarely, if ever, go back that far.
