Molecular Orbitals and Period 2 Diatomic Molecules (Sections)
(a) What does the term paramagnetism mean? (b) How can one determine experimentally whether a substance is paramagnetic? (c) Which of the following ions would you expect to be paramagnetic: O2 +, N2 2 -, Li2 +, O2 2 - ? For those ions that are paramagnetic, determine the number of unpaired electrons.
The Components of Matter Key Concepts: 1. Difference between elements, compounds, and mixtures. 2. Law of definite proportions. Elements compound and mixtures Definitions for components of matter. 1) What is the difference Elements: simplest type of substance with unique physical and chemical between elements and molecules properties. Molecules: a structure that consist of two or more atoms (of the same element) Ex: O 2
