class="p_first">Niobium was discovered in 1802 by Anders Gustaf Ekeberg, but many chemists thought niobium and tantalum were one and the same. Some felt that perhaps tantalum was an allotrope of niobium. Later, Rose, in 1844, and Marignac, in 1866, showed that niobic and tantalic acids were two different acids.</p> <p>The first relatively pure tantalum was produced by von Bolton in 1907. </p> </main> <div id="footer"> <footer> <div class="footer"> <div class="pure-g"> <div class="pure-u-1-2 pure-u-sm-1-2 pure-u-lg-1-4 pure-menu custom-restricted-width"> <ul class="pure-menu-list"> <li class="pure-menu-heading footer_h">Key properties</li> <li class="pure-menu-item"><a class="pure-menu-link" href="https://www.webelements.com/periodicity/eneg_pauling/">Electronegativity </a></li> <li class="pure-menu-item"><a class="pure-menu-link" href="https://www.webelements.com/periodicity/melting_point/">Melting point</a></li> <li class="pure-menu-item"><a class="pure-menu-link" href="https://www.webelements.com/periodicity/density/">Density </a></li> <li class="pure-menu-item"><a class="pure-menu-link" href="https://www.webelements.com/periodicity/molar_volume/">Molar volume</a></li> <li class="pure-menu-item"><a class="pure-menu-link" href="https://www.webelements.com/periodicity/ionis_energy_1/">Ionization energy (1st)</a></li> <li class="pure-menu-item"><a class="pure-menu-link" href="https://www.webelements.com/periodicity/covalent_radius/">Covalent radius</a></li> <li class="pure-menu-item"><a class="pure-menu-link" href="https://www.webelements.com/periodicity/metallic_radius/">Metallic radius</a></li> <li class="pure-menu-item"><a class="pure-menu-link" href="https://www.webelements.com/periodicity/abund_crust/">Abundance: earth's crust</a></li> </ul> </div> <div class="pure-u-1-2 pure-u-sm-1-2 pure-u-lg-1-4 pure-menu custom-restricted-width"> <ul class="pure-menu-list"> <li class="pure-menu-heading footer_h">Shop</li> <li class="pure-menu-item">Sorry, shop closed</li> </ul> </div> <div class="pure-u-1-2 pure-u-sm-1-2 pure-u-lg-1-4 pure-menu custom-restricted-width"> <ul class="pure-menu-list"> <li class="pure-menu-heading footer_h">Social</li> <li class="pure-menu-item"><a class="pure-menu-link" href="https://www.facebook.com/webelements.periodic.table">Facebook</a></li> <li class="pure-menu-item"><a class="pure-menu-link" href="https://twitter.com/periodic_table">Twitter</a></li> <li class="pure-menu-item"><a class="pure-menu-link" href="https://www.pinterest.com/periodictable/">Pinterest</a></li> </ul> </div> <div class="pure-u-1-2 pure-u-sm-1-2 pure-u-lg-1-4 pure-menu custom-restricted-width"> <ul class="pure-menu-list"> <li class="pure-menu-heading footer_h">Administration</li> <li class="pure-menu-item"><a class="pure-menu-link" href="https://www.webelements.com/nexus/your-privacy/" title="Your privacy">Privacy</a></li> <li class="pure-menu-item"><a class="pure-menu-link" href="https://www.webelements.com/nexus/about-webelements/" title="About WebElements">About</a></li> <li class="pure-menu-item"><a class="pure-menu-link" href="https://www.webelements.com/nexus/webelements-and-copyright/" title="Copyright information about WebElements">Copyright</a></li> <li class="pure-menu-item"><a class="pure-menu-link" href="https://www.webelements.com/nexus/acknowledgements/" title="Acknowledgements">Thanks...</a></li> </ul> </div> </div> </div> <address> <p> <a href="https://www.webelements.com/"><img class="logo_m" src="../_media/icons/logo_60.png" alt="WebElements home" /></a><br /> <strong>WebElements:</strong> THE periodic table on the WWW [<a href="https://www.webelements.com/">www.webelements.com</a>]<br /> <a href="https://www.webelements.com/nexus/webelements-and-copyright/">Copyright </a> 1993-2024 <a href="https://winter.group.shef.ac.uk/">Mark Winter</a> [ <a href="https://www.sheffield.ac.uk/chemistry/">The University of Sheffield </a> and WebElements Ltd, UK].
