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.
The oxidation number for H is almost always 1+.
The oxidation number of hydrogen is almost always 1 and should be so in AsH3.
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.
Silver almost always has an oxidation state of 1+ and Chlorine an oxidation state of 1-. Therefore, silver chloride has a simple formula of AgCl.
almost all are metals they react with other elements almost all are soft
The oxidation number for H is almost always 1+.
since the volt amphere turns in secondary neautralises the primary voltamphere turns making the magnetic flux in the core remain constant
The oxidation number of hydrogen is almost always 1 and should be so in AsH3.

its almost as the oxidation number rules you need to follow certain rules to determine the bond
unlike other capillaries glomerulus is connected to arterioles on both sides.It's pressure is higher than that of other capillaries and remains almost constant throughout the length of the capillaries.
Almost all of the elements in the periodic table are solids.
rust or oxidation can form on almost any metal surface
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)
Science is dependent on periodic table. It makes the study of elements easier.
Silver almost always has an oxidation state of 1+ and Chlorine an oxidation state of 1-. Therefore, silver chloride has a simple formula of AgCl.
Signals are aperiodic because they are not repetitive.
