Explanation:
All elements in group 3 have 3 levels of energy.
Na (sodium) has 3 valences the inner has 2 electrons, the middle has 8 electrons and the outer has 1 electron.
This will continue across the group 3 adding one more electron to the outer valence until Ar (argon).

Explanation:
1. Establish routines. Young children thrive on them, and they make perfect fodder for enhancing your child's memory.
2. Play memory games. Ask questions when you're out and about. For example, if you're passing a friend's house, ask, "Who lives there?" Games like this give children experience in recalling information.
3. Demonstrate how to perform tasks. Babies model their parents' actions. If you want your child to learn how to do something, such as stack one block on another, show him how and then give him a turn.
4. Talk with your child about her experiences. Focus on events that resonated strongly with her, such as a trip to the zoo. As she gets a little older, help her make stories out of her recollections.
