These elements are hafnium and zirconium.
which of the group IVB (14) metals is the least active
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
Group IA: +1 charge Group II2: +2 charge Group IIIB: +3 charge Group IVB: +4 charge Group VB: -3 charge Group VIB: -2 charge Group VIIB: -1 charge
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
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.
Group IA: +1 charge Group II2: +2 charge Group IIIB: +3 charge Group IVB: +4 charge Group VB: -3 charge Group VIB: -2 charge Group VIIB: -1 charge
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.
It is the group on the periodic table that starts with Carbon. It contains carbon, silicon, germanium, tin, lead, and ununquadium. All the elements have 4 electrons on the outer energy level.
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.
Colditz Castle. Oflag IVb. Pat Reid, Airey Neave & others proved otherwise !

Apollo 2 was an unmanned flight that tested the effects of weightlessness of the S-IVB tank. Near the end of the flight, the stage of the craft was pressurized to see how much stress it could handle. Even though the stage was destroying in the end, the mission was considered a success, having achieved all the mission objectives.
