  • first we need to represent it in electronic configuration
  • for example we take calcium
  • its electronic configuration is 2,8,8,2
  • so elements always try to attain like noble gas state
  • so its nearest noble gas have configuration of 2,8,8
  • so it need to lose two electrons to attain noble gas state
  • this is how you find valency of an element

please mark as brainliest
