question. why does sodium have 1 valence electron instead of 10? it has an atomic number of 11, meaning it has 11 protons. in order to find how many electrons there are you compare how much it needs to gain or lose to reach the same configuration as the nearest noble gas. of course we know that is is a group one element, and group one elements always need to lose an electron to have 10 electrons like neon. so why does sodium only have one valence electron instead of 10?
You are thinking of Core electrons. Those generally stay with an atom since the ionization energies for those are much higher. But valence electrons are the ones that are shared and leave, so that 1 that is lost for Na to get the electron config of Ne is your VE.
So impressed you mentioned the nominal difference between the North Pole and it’s actually polarity. Rarely high level of accuracy
👍 👍 👍
Great stuff, thanks for sharing
You're welcome
BTW I have heard of the term Lattice enthalpy, is that the same as lattice energy?

You are right!
