2 draw the formation of the compound

A carbon (iv) oxide Co2

B methane​

Answer 1

Step-by-step explanation:

A. Tabular form of the formation of the compound formed between X and Y (carbon and oxygen):

| Element | Electronic Configuration |

|---------|-------------------------|

| X | 1s² 2s² 2p⁶ 3s² |

| Y | 1s² 2s² 2p⁶ 3s² 3p⁵ |

B. Formation of the compound:

The compound formed between X and Y is carbon dioxide (CO2). Carbon (X) has an electronic configuration of 1s² 2s² 2p⁶ 3s², and oxygen (Y) has an electronic configuration of 1s² 2s² 2p⁶ 3s² 3p⁵.

Carbon has 4 valence electrons in its outermost energy level, while oxygen has 6 valence electrons in its outermost energy level. In order to achieve stability, carbon needs to gain 4 electrons, while oxygen needs to gain 2 electrons.

To form the compound CO2, carbon will share electrons with two oxygen atoms. Carbon will share 2 electrons with each oxygen atom, resulting in a double bond between carbon and each oxygen atom.

The formation of the compound can be represented as follows:

O = C = O

2. Drawing the formation of the compound:

In text format, the formation of the compound CO2 can be represented as:

Here, the central carbon atom (C) is bonded to two oxygen atoms (O) through double bonds. The structure of carbon dioxide is linear, with the carbon atom in the center and the oxygen atoms on either side.
