Question

An analogy with the oxoanions of sulfur, ${H_2}Te{O_3}$would be named?

Answer 1

In chemistry, periodic tables play a vital role. Now we are using a modern periodic table. This modern periodic table consists of totally $118$ elements. In the periodic table there are totally $18$ columns and $7$ rows. The columns are called groups. Hence, $18$ groups in the periodic table. The rows are called periods. Hence, totally $7$ period in the table. Among these elements salt will form depending on the cation and anion.

Complete Answer:
Generally salt will form when acids and bases react and are a side product of water.
The naming of salt is very important in chemical sciences. The naming salt is dependent on the nature of the anion and cation in the salt.
For example, the names of the three salts given below,
Sodium carbonate, the chemical formula of sodium carbonate is$N{a_2}C{O_3}$.
Sodium bicarbonate, the chemical formula of sodium carbonate is$NaHC{O_3}$.
Sodium sulfate, the chemical formula of sodium carbonate is $N{a_2}S{O_3}$.
According to the analogy, once sulfur is formed anion in salt, two names are possible. There is sulfate and sulfite.
The given chemical formula is ${H_2}Te{O_3}$, here we consider as tellurium as sulfur. Hence, the name of the given salt is tellurite. If we go through the acid and base concept, the name of the given chemical substance is tellurous acid.
According to the above discussion, we conclude an analogy with the oxoanions of sulfur, ${H_2}Te{O_3}$would be named as tellurous acid or tellurite.

Note:
In general, modern periodic table ordering is based on the atomic number of the atoms. The lowest atomic number starting from the first and followed by a higher atomic number.
Depending on the energy level of the outermost shell in the atoms, periods are classified and place the atom in respect period. Depending on the electrons shielding and size and physical behaviour of the atom, groups are coming.
In the modern periodic table, metallic atoms are placed on the left side of the table and non-metallic atoms are placed on the right side of the table. Metalloids and transition elements are placed in between metal and non-metal elements. Below the two rows are there. There are nothing but lanthanides and actinides. These are f-block elements. The salt will form depending on the metallic properties of cation and anion.
