The electron configuratin for tellurium with using the noble gas abbreviation is: [Kr] 5s2 4d10 5p4
[He]2s22p2
The atomic no of Cobalt is 27 which is intermediate of 18 for noble gas Argon and 36 for noble gas Krypton, practically Cobalt can't accept 9 electrons similarly can not donate nine electrons so it tends to reach the electronic configuration of Krypton by forming extra coordinate covalent bond.

No, it is a noble gas
It is a noble gas, which are in group 18 (far right column of the periodic table). It is in period (row) 4. It is element 36. Its abbreviation is Kr.
Radon is a noble gas and is radioactive.
no. it is a molecule, not a noble gas
