The discoverers named it moscovium after the Moscow oblast where the Joint Institute for Nuclear Research is located. The name moscovium was approved by IUPAC in November 2016. Encyclopædia Britannica, Inc. Moscovium is highly radioactive and has no known biological or industrial use beyond that of research.

Element 119 is expected to be a typical alkali metal with a +1 oxidation state.

The p-block elements are found on the right side of the periodic table. They include the boron, carbon, nitrogen, oxygen and flourine families in addition to the noble gases. The noble gases have full p-orbital’s and are nonreactive.

The elements in groups 1B through 8B (also known as 3 through 12) are called the transition metals. They are called d block elements because the electrons being added in this block of elements are being added to the d orbitals.

The f block elements are the lanthanides and actinides and are called the inner transition elements because of their placement in the periodic table due to their electron configurations. The f orbitals of the electron shell are filled with “n-2.” There is a maximum of fourteen electrons that can occupy the f orbitals.

When visible light falls on a transition metal compound or ion, the unpaired electrons present in the lower energe d-orbital get promoted to high energy d-orbitals, called d-d transition, due to the absorption of visible light. Therefore, transmitted light shows some colour complementary to the absorbed colour.

Those metals which have partially filled d-orbitals are transition metals. Zinc has completely filled d-orbital and should thus not be a metal for transition. This causes several different states of oxidation to form transition metals. …

Transition metals have partially filled d- orbitals so they can easily withdraw the electrons from the reagents or give electrons to them depending on the nature of the reaction. They also have a tendency to show large no. of oxidation states and the ability to form complexes which makes them a good catalyst.

Transition elements form coloured compounds because they have unfilled d orbitals.

Organic compounds tend to be colored when there is extensive conjugation, causing the energy gap between the HOMO and LUMO to decrease, bringing the absorption band from the UV to the visible region. Similarly, color is due to the energy absorbed by the compound, when an electron transitions from the HOMO to the LUMO.

Ion Color

The d-And-f-Block Elements. Iron is transition element but sodium is not because of the differentiating electron i.e. last incoming electron in iron acquires 3d orbitals to give [Ar] 3d6, 4s2 configuration with incomplete d-sub-shell, the characteristic of transition.

Copper

The 38 elements in groups 3 through 12 of the periodic table are called “transition metals”. These elements are iron, cobalt, and nickel, and they are the only elements known to produce a magnetic field.
