This is an introductory course for students with limited background in chemistry; basic concepts such as atomic and molecular structure, solutions, phases of matter, and quantitative problem solving will be emphasized with the goal of preparing students for further study in chemistry.

1Review Videos (I)
<p>Welcome! Over the eight weeks of the Introduction to Chemistry: Structures and Solutions course, we will begin discussions about the electronic structure of the atom, structures of molecules, phases of matter, and solutions. This week, we included some basic concept videos in Chemistry. These come from the partner course called Introduction to Chemistry: Reactions and Ratios. You can technically start with either course, but when these courses were originally designed, the Reactions and Ratios content came first, and you might find it helpful to complete that course before this course. If you are not familiar with the concepts of physical change v.s. chemical change, or significant figure and scientific notations, then please begin by reviewing video “Introduction”. I hope you enjoy this week's materials!</p>

2Quantum Number, Lewis Dot Structure
<p>Welcome to week 2! This week we will introduce quantum numbers, more information about periodicity, chemical bonding concepts including Lewis dot structures, resonance, bond order. Continue using the discussion forum for any questions, concerns, discussions, and suggestions. We value your feedback very much!</p>
<p>I hope you already found out how we captured the course logo from Colored Flames. Wasn't that fun to watch? Kudos to those of you who browsed the course, watched videos, submitted exercises, and/or posted on the discussion forum! Keep the great work going please.</p>

Perguntas Frequentes – FAQ
Quando terei acesso às palestras e às tarefas?
Ao se inscrever para um Certificado, você terá acesso a todos os vídeos, testes e tarefas de programação (se aplicável). Tarefas avaliadas pelos colegas apenas podem ser enviadas e avaliadas após o início da sessão. Caso escolha explorar o curso sem adquiri-lo, talvez você não consiga acessar certas tarefas.
O que recebo ao adquirir o Certificado?
Quando você adquire o Certificado, ganha acesso a todo o material do curso, incluindo avaliações com nota atribuída. Após concluir o curso, seu Certificado eletrônico será adicionado à sua página de Participações e você poderá imprimi-lo ou adicioná-lo ao seu perfil no LinkedIn. Se quiser apenas ler e assistir o conteúdo do curso, você poderá frequentá-lo como ouvinte sem custo.
Qual é a política de reembolso?
Existe algum auxílio financeiro disponível?
Will I receive a transcript from Duke University for completing this course?
No. Completion of a Coursera course does not earn you academic credit from Duke; therefore, Duke is not able to provide you with a university transcript. However, your electronic Certificate will be added to your Accomplishments page - from there, you can print your Certificate or add it to your LinkedIn profile.
