IV. DIAGRAM REPRESENTATION (26-33)Draw a particle model for the following : ( 2pts each) 1 Sodium 2.Hydrogen 3. Mixture of argon and neon 4.mixture of hydrogen chloride and hydrogen fluoride

What are the first three quantum numbers for the electrons located in subshell 2s?

I'm learning about the periodic tables and what each subject's configuration is. for example, hydrogen is 1s^1, but i don't understand how you get that. can someone me understand how to figure out how to figure this out? sorry if the question makes no sense, but it would really a lot if you could me understand! you so much if you can!

If it is an isoelectronic series select true, if not select false. o2-, s2-, se2-, te2- na+, k+, rb+, cs+ n3-, p3-, as3-, sb3- ag, cd+, sn3+, sb4+ f-, cl-, br-, i- f-, ne, na+, mg2+ s2-, s, s6+
