Document Summary
All atoms contain a positively charged nucleus neutrons surrounding it are electrons in orbitals that has protons t freely charged) . And orbitals energy about and atoms are arranged in in two the first s orbital orbital p. Ions . atoms that have lost or gained electrons . Electronegativity : how much an atom wants an electron . En increases an atom to attract e- "s . to e- 5 . up and to the right. And count count if an octet is fulfilled the formal charge. Add up total valence electrons of all atoms . Step 4 : pair electrons . charge of with valence valence electrons . electrons around it. "s) - f # of e "s lone pairs) - f # of bonds ) # of e- "s : bone pair = 2 e "s bond de "s. Charge is bad ! charge makes things unstable more reactive electron missing an extra electron t ve.
