The valency of molybdenum can vary depending on the specific compound it is present in. In most of its compounds, molybdenum exhibits a valency of 6 due to the presence of six valence electrons in its outermost shell. However, in some compounds such as MoO3, MoCl5 and MoF6, molybdenum can exhibit a valency of 4, 5 and 6 respectively.

It should be noted that the term "valency" is used less frequently in modern chemistry, and has been largely replaced by the concept of oxidation state or oxidation number. The oxidation state is a measure of the degree of oxidation of an atom in a compound, and can be calculated by assigning electron charges to each atom based on their electronegativity and bonding arrangements. For example, in molybdenum hexafluoride (MoF6), molybdenum has an oxidation state of +6 because it has lost six electrons and has a net charge of +6.

The valency of niobium refers to the number of electrons that niobium can lose or share when it forms a compound. Niobium has a valency of 5, meaning it can lose or share up to 5 electrons when forming a compound.

The reactivity of niobium with other elements or compounds is dependent on its valency. Niobium with a high valency (e.g. +5) tends to be more reactive than niobium with a lower valency (e.g. +2). This is because higher valencies indicate that niobium has more available electrons to interact with other elements or compounds.

In addition, the type of element or compound that niobium reacts with can also influence its reactivity. For example, niobium tends to react readily with oxygen to form niobium oxide, regardless of its valency.

Overall, the valency of niobium plays an important role in determining its reactivity with other elements and compounds, with higher valencies generally indicating greater reactivity.

Niobium is a transition metal with an atomic number of 41. Its electronic configuration is [Kr]4d^4 5s^1, with four electrons in the d orbital and one electron in the s orbital.

Niobium can exhibit different valencies, including +2, +3, +4, and +5. The valency of niobium depends on its atomic structure and the number of electrons it can lose or gain to form chemical bonds.

In its most common oxidation state of +5, niobium loses its outermost 5s electron and one electron from the 4d subshell, leaving it with a stable 4d^3 electronic configuration. This configuration corresponds to a half-filled d-subshell, which is energetically favorable.

Niobium can also exhibit a valency of +4 by losing two electrons from the 4d subshell, leaving it with a 4d^2 configuration. In this case, the d-subshell is not half-filled, but it is still relatively stable due to the pairing of electrons in the d-orbitals.

In contrast, the +2 and +3 valencies of niobium are less common and involve the loss of more electrons from the 4d subshell. These valencies are less stable because they lead to partially filled or empty d-orbitals, which are energetically unfavorable.

Overall, the valency of niobium is determined by its atomic structure, particularly the number and arrangement of electrons in its d and s orbitals, and the number of electrons it can lose or gain to form chemical bonds.
