Define velency by taking example of silicon and oxygen?

Question

Answer

Taking or lossing the number of electrons by an element to complete their octen (astak) is called the valency of the elementex- atomic number of oxygen is 8electronic configuration is 2,6here it take 2 electron to complete octenso the valency is 2

Answer

Valency is the capacity of an atom of getting combined to another atom.-Oxygen has atomic number 8 and has valency 2.-Silicon has atomic number 14 and has valency 4.-Silicon can either take 4 ions or give 4 ions to oxygen.

Answer

Silicon valency is 14 oxygen valency is  8

Answer

Valency is the combining capacity of an atom. Valency of silicon is 4 And valency of oxygen is 2.

Answer

The combining capacity of an atom is known as valency and valency of oxygen is 2 and silicon is 4

Answer

Valency of Silicon and Oxygen

The valency of an element refers to its combining capacity with other elements to form compounds. It indicates the number of electrons an atom can gain, lose, or share in order to achieve a stable electron configuration. Silicon and oxygen are two elements that exhibit different valencies.

Valency of Silicon:
Silicon is a chemical element with the symbol Si and atomic number 14. It is a metalloid and is commonly found in the Earth's crust. Silicon has a valency of four, which means it can form covalent bonds by sharing four electrons with other atoms.

Silicon forms stable compounds by sharing its four valence electrons with other elements. For example:

1. Silicon Dioxide (SiO2): In silicon dioxide, silicon shares two of its electrons with each of the two oxygen atoms, forming a covalent bond. This results in the formation of a stable molecule with a tetrahedral structure.

2. Silicon Tetrachloride (SiCl4): In silicon tetrachloride, silicon shares one electron with each of the four chlorine atoms, forming four covalent bonds. The resulting molecule has a tetrahedral shape.

Valency of Oxygen:
Oxygen is a chemical element with the symbol O and atomic number 8. It is a highly reactive nonmetal and is the third-most abundant element in the universe. Oxygen has a valency of two, meaning it can gain or share two electrons to achieve a stable electron configuration.

Oxygen commonly forms stable compounds by gaining two electrons to fill its valence shell. For example:

1. Water (H2O): In water, oxygen shares two electrons with each of the two hydrogen atoms, forming two covalent bonds. The resulting molecule has a bent shape.

2. Carbon Dioxide (CO2): In carbon dioxide, oxygen shares two electrons with the carbon atom, forming two double bonds. This results in a linear molecule.

Summary:
- Silicon has a valency of four, while oxygen has a valency of two.
- Silicon forms stable compounds by sharing its four valence electrons, whereas oxygen gains or shares two electrons.
- Examples of compounds formed by silicon include silicon dioxide (SiO2) and silicon tetrachloride (SiCl4).
- Examples of compounds formed by oxygen include water (H2O) and carbon dioxide (CO2).
- These compounds play essential roles in various natural and industrial processes.
