Chem Covalent Bonding (simple and giant)

Question 1

What is Covalent Bonding

Answer 1

A chemical bond that involves the sharing of electrons bw atoms

Question 2

what type of elements are involved in covalent bonds

Answer 2

non metals

Question 3

define a simple covalent structure with an example

Answer 3

A simple covalent structure is a series of molecules held together by covalent bonds but held bw each other with intermolecular forces. eg. h20

Question 4

define a giant covalent structure with an exampe

Answer 4

A giant covalent structure is a series of atoms entirely held together by covalent bonds. eg. Diamond- carbon with 4 bonds

Question 5

define allotropes

Answer 5

different forms of the same element in the same state

Question 6
