Ionic bond formation

Question 1

How does a sodium atom become a sodium ion (metal)

Answer 1

sodium atom loses an outer electron making its outer shell full a stable ion is formed with a 1+ charge

Question 2

How does a chlorine atom become a chloride ion (non-metal)

Answer 2

chlorine atom gains an outer electron making its outer shell full a stable ion is framed with a 1- charge

Question 3

How oppositely charged ions form an ionic bond

Answer 3

electron transfers from a metal to non-metal atoms and become ions, both ions have complete outer shells with opposing charges so an electrostatic attraction occurs between the ions, called an ionic bond

Question 4

What goes around the electron diagram to show it is an ion

Answer 4

square brackets

Question 5

If an ion loses an electron it will be + or -

Answer 5

+

Question 6

If an ion gains an electron it will be + or -

Answer 6

-

Question 7

If a magnesium atom electron structure is 2,8,2 what will its ion electron structure be

Answer 7

[2,8]²⁺
