the transition metals constitute groups 3 through 12 and are sometimes called d-block elements because of their position in the Periodic Table; while they all have the same valance electron orbital 'd'.
The inner layer of electrons that was in transition were between stable groups.
Because of their position in the periodic table, unlike the main-group elements, the transition metals in each group do not have identical outer electron configurations.

Bohr model explain these spectra.
These are elements from the group 17 - halogens; a strong electrostatic attraction exist beween atoms.
spectra of elements with multi-electron atoms
The elements are classified as metals and non metals. Apart from this, there are elements that are metalloids, transition elements, inert in nature.
Apart from metals and non-metals, metalloids are also present. Transition elements are also present in periodic table.
In steels, alloying elements such as silicon, chromium, molybdenum, aluminum, titanium, niobium, etc., stabilize the (body-centered cubic) ferrite phase. These elements are referred to as ferrite stabilizers. Alloying elements such as carbon, nitrogen, manganese, nickel, copper, etc., stabilize the (face-centered cubic) austenite phase. These elements are referred to as austenite stabilizers.

512 subsets
Elements within the same row have the same electron configurations in their valence shell. Elements in the same period show trends in atomic radius, ionization energy, electron affinity, and electronegativity.
Autonomous items in the balance of payments capture transactions that private agents undertake when they maximize profits or welfare. These items are sometimes referred to as above the line items. Accommodating items reflect government actions aimed at altering the size and the composition of the balance of payments, and they are sometimes referred to as below the line items.
