Chapter 2, Problem 3MIC

Chlorine is an element with the symbol Cl. Draw and label atomic structure of chlorine indicating the number and locations of protons, neutrons and electrons in one atom of chlorine.

What are differences between covalent bonds (both polar and nonpolar) and ionic bonds. Recognize examples of compounds with each type of bond.

Consider iron (Fe), hydrogen gas (H2), and ammonia (NH3).Which of them is or are atoms? Which of them is or are molecules? Which of them is or are compounds? Explain eachanswer

What is the smallest unit of an element that retains the properties of that element?

Nucleus acids are organic compounds. In addition to hydrogen, what element is an essential component of all organic compounds?

Atoms A and B interact to form a compound, AB2. When measured, atom A has a partial negative charge and atom B has a partial positive charge. From this information, we can conclude what? Select only ONE answer choice. Note: - means "approximately equal to" , A > B means "A is greater than B" , and A B: AB2 is hydrophilic Not enough information to answer the question

Organic molecules contain both carbon and hydrogen atoms (and may have a few other elements as well). There are millions of kinds of organic molecules. They include molecules like: What is the smallest organic molecule?

Knowing the atomic mass of an element allows inferences about which of the following?     the number of protons plus neutrons in the element     the number of protons plus electrons in the element     the number of electrons in the element     the number of protons in the element

For hydrogen bonds, answer these three questions: A) Are they found in polar, non-polar or both types of molecules? B) Are they strong or weak? C) Are they found inside a molecule or between a molecule?
