First of all: telerium is not a correct name of an element.Most probably is meant:Tellurium, Te, a chemical element that has the symbol Te and atomic number 52 rather than:Terbium, Tb, a chemical element with the symbol Tb and atomic number 65.Occupied (sub)levels are:Te: [Kr] 4d10 5s2 5p4(or Tb: [Xe] 4f9 6s2 )

How many electrons are present in the 3d subshell?

On the periodic chart, the element with 5 electrons in its 3d orbital can be quickly identified. Elements with partially filled d-orbitals are located in the middle section, the "transitional metals." 3d is the first d-orbital, so we look in the first row of the middle section. This section fills the orbital by one more electron per element, so the one with 5 electrons is the fifth from the left.... Manganese! Atomic number 25.

The element Mn has how many valence electrons?

In actuality Mn has SEVEN valence electrons, not really 2 as might be predicted. The reason for this is that Mn is [Ar]3d5 4s2, and as a transition element, not only are the 4s electrons available for bonding, but so are those in the d orbital. So, the 5 electrons in 3d and the 2 electrons in 4s are all considered as valence electrons.
