These elements are hafnium and zirconium.
no it is in Group 4 (Old IVA or IVB, depending on which form)
This group 4 in the moden table or group IVb in the older version
The periodic table has a regular repeating pattern based on the arrangement of elements by increasing atomic number. Elements in the same group have similar chemical properties due to their shared number of valence electrons. This pattern helps predict the chemical behavior of elements.

Silicon is part of the Carbon Group, which is referred to as Group IV. In the old IUPAC and CAS systems, it was called Group IVB and Group IVA, respectively.

British Virgin Islands. Not sure why it is not BVI, which makes more sense to me.
any of the set of metallic elements occupying a central block (Groups IVB-VIII, IB, and IIB, or 4-12) in the periodic table, e.g., iron, manganese, chromium, and copper. Chemically they show variable valence and a strong tendency to form coordination compounds, and many of their compounds are colored.

Identify every source of capital financing, including: (a) each type of debt and (b) each class of stock.Determine the market value of each source of capital. If a source of capital has no market value, then estimate its present value. Denote this market value as IVa for the first source of capital and IVb for the second, etc.Determine the return on each source of capital. For debt, this is pretax borrowing rate. For equity, it is the cost of equity capital rate using the capital asset pricing model or a multi-factor model. Denote each rate as ra, rb, etc.Now find the weighted average of the rates, based on the values of the different sources of capital. Here's the formula if you have two sources of capital, "a" and "b."WACC = [ra x IVa/(IVa+IVb)] + [rb x IVb/(IVa+IVb)]
On the older style of periodic table, you will notice that the groups are labelled Group I, Group II, etc with Roman Numerals. There were also A' s and B's assigned - for example above scandium was Group IIIA and above aluminum was IIIB. Therefore, the numbering system going across the table was Groups IA, IIA, IIIB, iVB, VB, VIB AND VIIB, VIII. Group VIIB was known as Group 7 or the Halogens. It is now know as group 17.
During the Saturn V space flight, the first stage (S-IC), second stage (S-II), and third stage (S-IVB) were jettisoned after their respective fuel was expended and they were no longer needed. The S-IVB stage carried the Apollo spacecraft into Earth orbit before separating to continue on its trajectory to the Moon.
Carbon belongs to group 14 on the periodic table, which is also known as the carbon group. This group includes carbon, silicon, germanium, tin, and lead. Carbon is a nonmetal and is known for its ability to form a wide variety of compounds due to its unique bonding properties.
Colditz Castle. Oflag IVb. Pat Reid, Airey Neave & others proved otherwise !
During a Saturn V launch, various stages of the rocket jettison as they are expended. The first stage (S-IC) jettisons about 2 minutes after liftoff, followed by the second stage (S-II) about 8 minutes into the flight. The third stage (S-IVB) separates once the desired orbit is achieved. Finally, the Apollo spacecraft separates from the S-IVB stage before entering lunar orbit.
