Chemistry Fundamentals Quiz

Properties of Water

• Ice is the phase of water that is less dense than its liquid form, allowing it to float on water.

Chemical Compounds

• The most important type of compound that lacks carbon and hydrogen is known as inorganic compounds.

Periodic Table Groups

• The group with the most elements in the Periodic Table is the Transition Metals group.
• The two most reactive groups of metals are the Alkali Metals and the Alkaline Earth Metals.
• The most unreactive group of elements is the Noble Gases.
• The group known as the halogens includes Fluorine, Chlorine, Bromine, Iodine, and Astatine.

Structure of the Periodic Table

• There are a total of seven periods in the Periodic Table of Elements.

Reactive Non-Metals

• The two most reactive non-metals are Fluorine and Chlorine.

Atomic Structure

• Atoms are made up of three main particles: protons, neutrons, and electrons.

Chemical Descriptions

• Chemical formulas provide a concise way to describe the composition of a substance, indicating the type and number of atoms present.
• Chemical equations are used to represent chemical reactions, illustrating the transformation of reactants into products.

Types of Compounds

• Ionic compounds are formed between positive and negative ions, typically between metals and nonmetals.
• Covalent compounds usually occur between two nonmetals, involving the sharing of electrons.

pH Ranges

• The pH range of acids typically lies between 0 and 7.
• The pH range of bases is generally from 7 to 14.
