How many valence electrons are in Tc

Tc is Technetium, and it has an atomic number of 43. Its atomic configuration is [Kr] 5s (1) 4d (5) [I'm on my phone so I can't do numbers on shoulders, pretend that 1 and 5 are on the s and d's shoulder]

The outside most ring is the 4d (5), and the d orbital can hold ten electrons.

Valence electrons are electrons, in you could say the outside ring that isn't filled, the extra ones. In this case, there are 5.
