∙ 12y agoYes the element is Technetium (Tc)
Kr has 36 protons. Now we have to add 6+1 ie 7 along with 36. Hence the atomic number comes to be 43. The element which has 43 protons is the only one and that one is Technetium. This was first found because of Mosley's law related to the diffraction of Xrays.

'Kr' is the chemical symbol for 'Krypton'.
The word 'Krypton' comes from Classical Greece, and means 'hidden'. because it was the laST NOBLE GAS to be found/isolated.
