How do ions form?
SAMPLE 1: 
Neutral lithium atom → Charged lithium cation
GUIDE QUESTIONS:
  • (a) What is its atomic number or proton number? 
  • (b) What is its electron number?
  • (c) What period is it located in the PT? 
  • (d) So, how many shells does it have? 
  • (e) What is its electronic configuration?
  • (f) So, what group does it belong to? How did you know? 
  • (g) Is it a metal or non-metal? 
  • (h) Will it change to cation or anion? Why? 
  • (i) Will it lose or gain electron/s? How many? 
  • (j) How will you show it in Bohr's model?
  • (k) Why does an atom need to change into ions? 
  • (l) What makes an ion stable? It has a full outer shell.
