Bonding

Question 1

How is an ionic bond formed?

Answer 1

through the transfer of electrons between metals and non metals

Question 2

How is a covalent bond formed?

Answer 2

When non metals share their electrons in order to become stable

Question 3

What are the 3 types of covalent bonds?

Answer 3

single bond
double bond
triple bond

Question 4

What are the similarities between covalent and ionic bonds?

Answer 4

They both use their valence elctrons
They both bond to become stab;e

Question 5

What is metallic bonding?

Answer 5

It occurs in metals. The atoms are packed tightly in rows to form a metal lattice and their valence electrons become delocalised.

Question 6

What does it mean by delocalised electrons?

Answer 6

They are no longer assiciated with a specific atom and are free. This forms cations and a sea of mobile electrons.

Question 7

How is an ionic compound formed?

Answer 7

When ions of opposite charges attract each other to form an ionic bond

Question 8

What is the metal lattice held together by?

Answer 8

The electrostatic force between the delocalizedn electrons and the cations
Also called the metallic bond
