Known, but unknown elements?

[Mudalia]

<p>Hi all,</p><p>This is my first post on here and I'd just like to ask wether the properties of elements 113, 115 and 117 have ever been documented anywhere?</p><p>&nbsp;I ask because Im entering my final year at school and Im currently taking Physics and Chemistry, eveytime I look at the peroidic table theres always these three blank spots and I wonder about the properties that they might posses and why they wouldn't be listed.</p><p>&nbsp;The only explaination I can come with is that, the element decays too fast for further study and only exists in small quantities around various labs.</p><p>Thanks!</p>
