Answer:

Well, how many electrons does a sodium atom have?

Explanation:

It has #11# electrons. How did I know this? How will you know this if it is asked in your exam? And we write the electronic configuration in the usual #"aufbau"# way...

#Na:1s^(2)2s^(2)2p^(6)3s^1#

The #3s# electron is READILY LOST, and this sodium metal is a very capable REDUCTANT....
