Lecture 2

Lecture 2

Lecture 2. Shielding and effective nuclear charge Z* In polyelectronic atoms, each electron feels the attraction of the nucleus and the repulsion of the other electrons (both n and l must be taken into account) Each electron acts as a shield

Atomic Structure and Periodicity

Atomic Structure and Periodicity

Atomic Structure and Periodicity. The Puzzle of the Atom. Protons and electrons are attracted to each other because of opposite charges Electrically charged particles moving in a curved path give off energy Despite these facts, atoms don’t collapse. Wave-Particle Duality.
