Why IVA group elements general electronic configuration is ns2np2 Carbon Group or Tetrels: - Group 14 (IVA) - 4 valence electrons Nitrogen Group or Pnictogens: - Group 15 (VA) - 5 valence electrons Oxygen Group or Chalcogens: - Group 16 (VIA) - 6 valence electrons salient features of group 14 (carbon family) elements * The general outer electronic configuration of group-14 elements is: ns 2 np 2 . * The atomic numbers, electronic configurations, corresponding periods and the chemical nature of these elements are tabulated below. As the valence electrons between IIA (s 2) and IVA (p 2) are similar, the IVA group of elements is settled on the A-site ion position with fixed BB′ combinations as FeM (M = Mo, Re, and W). The p–d hybridization with double exchange is the main course of the ferrimagnetic half-metallic properties. Some properties of the group IVA elements are summarized in the table.
Introduction group IB. Group IB includes following elements: Copper - [Cu], Silver - [Ag], Gold - [Au]. Collectively known as the “coinage metals” because of their former usage, these elements were almost certainly the first three metals known to man.

Click here👆to get an answer to your question ️ The correct statement with respect to the property of IVA group elements is: The wettability of molten aluminum alloys containing 5% of Ti, Zr and Hf in IVa group to SiC was measured by the dipping method at 1273 to 1373K. These elements have an effect to improve the wettability of aluminum to SiC. EPMA analysis shows that these elements are concentrated and form carbides at the SiC-aluminum alloy interface. The wetting process were analysed by an equation derived in The most important compounds of the group VA elements are those of nitrogen and phosphorus. Both elements are essential to all living organisms, and both are progressively removed from soil when plants are cultivated and crops harvested.

GROUP IV ELEMENTS Group IV consists of Carbon – C, Silicon – Si, Germanium – Ge, Tin – Sn and Lead – Pb. This is one of the groups in which the transition from non-metals, C and Si through typical metalloid Ge, to weakly electropositive metals, Sn and Pb can be clearly seen.

The roman numerals used correspond to the last digit of today's naming convention (e.g. the group 4 elements were group IVB, and the group 14 elements were group IVA). In Europe, the lettering was similar, except that "A" was used if the group was before group 10, and "B" was used for groups including and after group 10.

Elements belonging in Group IVA (eg - C, Si) all have electron configuration ending in ns 2 np 2 (the superscripts total to '4' indicates there are 4 valence electrons for elements belonging to Group IVA).
