An element is a main constituent of paper, diamond and clothes etc. It forms covalent bonds with itself and other elements:- (1) identify the element (2) write the electron dot structure of its oxide. (3) draw the electron dot structure of methane and ethene.

Respuesta :

PBCHEM

Answer 1) Carbon - It is the element which is the main constituent of the paper in the form of cellulose, diamond is made of completely carbon and clothes are mostly made from carbon based fibers. Also, it forms covalent bonds with itself and other elements too because it has 4 valence electrons in its valence shell so, it can either donate or accept electrons to attain a stable octet state.


Answer 2) The electron dot structure of the oxides of carbon are of two types;

i) CO and ii) [tex] CO_{2} [/tex]


The images are attached for the electron dot structures.


Answer 3) The structure of methane and ethene is attached in the image.

Explanation:

1) The main constituting element in paper , diamond  and cloths is carbon atom.This because carbon atom has unique property of creating strong covalent bonds with other carbon atoms which give rises to complex organic  structures.

2) There two oxides formed by carbon which are : carbon-dioxide [tex]CO_2[/tex]and carbon monoxide CO.

Structure are given in an image.

3) In molecule of methane there is a 1 mol of carbon.

Methane = [tex]CH_4[/tex]

In 1 molecule of ethene there are two carbon atom double bonded to each other.

Ethene = [tex] C_2H_4[/tex]

Electron dot structure of methane and ethene are given in an image
