Re: Ligand binding
Ligand bonds to the central atom. For coordination compounds, it forms between the compound and the element that goes in to share

well radicals just end up going on the central atom. I dont think you count that in for formal charge

Re: question
Electron affinity is how likely an atom will take an electron or how much it "wants" an electron. Electronegativity is how strongly an atom will attract shared electrons to itself (more related to bonding). Both electron affinity and electronegativity show similar trends on the periodic t...

Re: question
electron affinity is the energy released when electrons are added
electronegativity is the attraction an atom has in order to get more electrons

Ejection of electrons in metals
Professor Lavelle mentioned that uv lights (high frequency beams) cause the ejection of electrons in metals. So does the sun cause the ejection of electrons of metal buildings on a daily basis? If so what are the consequences?

Re: Module 3: Limiting Reactant Calculations, Question 19
the limiting reactant is the one you have a shortage of to make something. Think of it as a recipe. like if u want to make 1 cake, you need 3 eggs, 1/2 c of milk, and 3/4 c of flour. I have 2 eggs, 3/4 c of milk, and 1 c of flour. Here the limiting reactant is the eggs.
