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'.

No, Rutherford's model of the atom fails to explain the discrete spectral lines of elements. Bohr's model, which incorporates quantized energy levels and electrons moving in well-defined orbits, successfully explains the spectral lines of elements by linking them to the transitions between electron energy levels.
These are elements from the group 17 - halogens; a strong electrostatic attraction exist beween atoms.

An equation written may or may not be balanced. It is balanced if the number of elements on both sides of the arrow, that is before and after the reaction, is equal. Sometimes the number of elements is not the same on both sides of the arrow, then we need to balance the equation. This is done in accordance to the law of conservation of mass which states that the mass of a substance does not get destroyed or created due to a chemical reaction.
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.
Endosymbiosis explains the transition from prokaryotes to eukaryotes.
No, all elements on the periodic table cannot be classified as either metals or nonmetals. Some elements, known as metalloids, have properties that fall between those of metals and nonmetals. These elements are typically found along the zigzag line on the periodic table.

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.
The demographic transition model describes the transition from high birth and death rates to low birth and death rates as a country develops economically. This model helps explain how a country's population growth is influenced by factors such as industrialization, healthcare improvements, and education levels. By understanding which stage of the demographic transition model a country is in, policymakers can anticipate future population trends and plan accordingly.

Element 109 has been discovered and repeatedly generated. It has been named Meitnerium (Mt) and is part of the Cobalt series (which is in the transition metals).
