The d-metals iron, copper, and manganese form cations with different oxidation states. For this reason, they are found in many o
choli [55]

Answer:

They have electrons in their 3d- and 4s-orbital for bond formation.

Explanation:

d- metals or transition metal are metal which form ion with partially filled d-orbital. Examples are iron and manganese.

The metals have 2 electrons in their 4s orbital. If only this is used for bonding, they will form compounds where they have oxidation State of +2 as seen in MnO.

If two 4s and one of 3d electrons are used, oxidation state of +3 is formed as seen in FeCl3.

If two 2s electron I used with two 3d electrons, compound with oxidation state of +4 is formed as seen in MnO2

Polyatomic ions: CH_3COO^-, NO_3^-, NH^+, CN^-, Li^+, and OH^-

Monatomic ions: Ca^{2+, O^{2-, and Fe^{3+

<h3>Monoatomic vs Polyatomic Ions</h3>

In chemistry, monoatomic ions are ions that consist of only a single type of atom. They are usually positive or negatively charged and are otherwise known as simple ions. Examples include  Ca^{2+, O^{2-, and Fe^{3+

Polyatomic ions, on the other hand, are ions that consist of more than one atom, unlike monoatomic ions. The two or more atoms are covalently bonded and the entire structure behaves like a single chemical entity in reactions. Polyatomic ions are otherwise known as molecular ions.

Examples of polyatomic ions are  CH_3COO^-, NO_3^-, NH^+, CN^-, Li^+, and OH^-

Thus, from the diagram:

  • Polyatomic ions: CH_3COO^-, NO_3^-, NH^+, CN^-, Li^+, and OH^-
  • Monatomic ions: Ca^{2+, O^{2-, and Fe^{3+
