Periodic table trends Study guides, Class notes & Summaries

The mole concept - Answer-A method that allows the relative number of reactant particles involved in a chemical reaction to be known Avogadro's number - Answer-number of representative particles in a mole, 6.02 X 10^23 Basic structures of atoms - Answer-There is a nucleus in the center surrounded by an electron cloud or field Quantum numbers - Answer-Quantum numbers describe values of conserved quantities in the dynamics of a quantum system. In the case of electrons, the quantum numbers ca...

CEM 141 MSU Exam 3 Latest Update Graded A+ Ionization Energy energy required to remove an electron from an atom in the gas phase Left Side Electrons have weaker attractions to remove electrons *easier to remove electrons from the left side of the table than the right side* Does it take MORE or LESS energy to remove an electron from Li than from Na? MORE Why? Because as we move down a group, the orbitals become larger and weaker. While going across the effective nuclear charge in...
