Chapter 1 Carbon and Its Compounds CHECKPOINT PROBLEMS Practice Problem 1.1 a) S — 1s2 2s2 2p6 3s2 3p4 b) Cl — 1s2 2s2 2p6 3s2 3p5 c) Na+ — 1s2 2s2 2p6 1-2 Copyright © 2018 Nelson Education Limited Practice Problem 1.2 a) Count valence electrons. Build a basic bonding framework and account for electrons used. Add remaining electrons and check for formal charges. The molecule has a lone pair on the nitrogen. All other electrons are bonding electrons. b) Count valence...

CHEMISTRY A LEVEL WITH SATISFIED SOLUTIONS What are the two elements which are exceptions to the electron configuration? - CORRECT-The two exceptions for this is copper and chromium. In both cases, the 4s subshell contains only one electron, even though there are electrons in the 3d subshell. To explain this, its because the 3d subshell is more stable when it is either half full, or completely full. So in the case of chromium, by having only one electron in the 4s subshell, ...

Aufbau principle - -procedure in which the electron configuration of the elements is determined by "building" them in order of atomic numbers, adding one proton to the nucleus and one electron to the proper subshell at a time core electron - -electron in an atom that occupies the orbitals of the inner shells electron configuration - -electronic structure of an atom in its ground state given as a listing of the orbitals occupied by the electrons Hund's rule - -Every orbital in a subshell...

Protons correct answers defines the element; positive charge; equal to the atomic number Neutrons correct answers equal to mass number-number of protons; neutral charge Electrons correct answers negative charge; dependent on the charge of the atom Cations correct answers Positively charged ions Anions correct answers Negatively charged ions Isotopes correct answers when the number of neutrons varies but it has the same number of protons ex) Ne-20 and Ne-22` What was believed un...
