Because within a group, the elements all have the same number of valence electrons, so their "combining power" (oxidation number) is relatively the same. In a period, the number of valence electrons increases going left to right, so the "combining power" changes.

What is saturation region in general?

Saturation region is one in which the output current is independent of the input and remains almost constant. Hence, MOSFETs in saturation are modeled as current sources( whose current is independent of voltage across it)


Which example describes constant acceration due only to a change in direction?

Centrepetal force-orbits E.G. Earth orbits the sun at a constant speed but also changes its direction, thus its velocity. This means that the almost constant change in velocity causes there to be a constant acceleration because of the change on direction.


The oxidation no of c in HCN and HNC IS?

In both HCN and HNC molecules, the oxidation number of carbon (C) is -3. This is because hydrogen (H) is almost always assigned an oxidation number of +1, and nitrogen (N) is usually assigned an oxidation number of -3. By assigning the oxidation numbers of H and N, we can then determine the oxidation number of C that makes the overall charge of the molecule neutral.


Oxidation numbers for H2PO4-?

In H2PO4-, oxygen has the formal oxidation number -2, phosphorus has the formal oxidation number +5, and hydrogen has the formal oxidation number +1. The formal oxidation numbers for oxygen in almost all oxyanions and for hydrogen in almost all acid anions have these values, so that the remaining element can be assigned a formal oxidation number by the requirement of satisfying the total electrical charge if any shown in the formula.
