Properties and models of bonding

Question 1

What type of chemical bond is formed through the transfer of one or more electrons from one atom or group of atoms to another atom or group of atoms?

Answer 1

Ionic bond

Typically involves metals from Groups 1 & 2 combining with nonmentals from Group 16 & 17.

Question 2

What compound is formed when ionic bonds are present?

Answer 2

Ionic compound

Ionic compounds are composed of cations and anions that have strong attraction to each other.

Question 3

What chemical bond is formed through sharing of one or more pairs of electrons between 2 atoms?

Answer 3

Covalent bonding

Commonly occurs between non metal groups 13-17.

Question 4

What is metallic bonding?

Answer 4

Metallic bonding is the strong, electrostatic attraction between positive ion and negative electron cloud.

This can not be represented by Lewis structure.

Question 5

What determines the degree of ionic character in a covalent bond?

Answer 5

Electronegativity

It is an ability of an atom to attract electrons to itself
