Connect the common names of chemicals to their chemical names. Plus, see the chemical formulas of everyday household chemicals.
Learning Objectives. To describe the composition of a chemical compound. To name covalent compounds that contain up to three elements. As with ionic compounds, the system for naming covalent compounds enables chemists to write the molecular formula from the name and vice versa.
Learn about the Chemical Formula for Nitrogen, List of chemical compounds and their common names and relationship between elements
Chemical Names and Formulas. 9.1. • ELECTRONS AND THE STRUCTURE OF ATOMS. • BONDING AND INTERACTIONS. For students using the Foundation edition, Naming Ions. assign problems 4, 8–15. Essential Understanding Ions are named by determining their charges and applying certain rules. Reading Strategy.
• Write the chemical names and formulas of common chemical compounds. • Describe the colors and textures of common ionic compounds. • Synthesize chemical compounds, and write their names and formulas.
But we can hardly talk about chemistry without mentioning some chemical substances, all of which do have names— and often, more than one! All we will try to do here is cover what you need to know to make sense of first-year chemistry.
Compounds that contain predominantly carbon and hydrogen are called organic compounds, whereas compounds that consist primarily of elements other than carbon and hydrogen are inorganic compounds. Diatomic molecules contain two atoms, and polyatomic molecules contain more than two.
Here are printable chemistry worksheets in pdf format. The first worksheet in each set asks you to name the chemical formula based on the chemical name. The second worksheet asks for the chemical name based on the chemical formula. Answer keys are provided separately.
Here is a look at the most common types of chemical formulas: empirical formulas, molecular formulas, condensed formulas, and structural formulas. Parts of a Chemical Formula. Element Symbols: Write the one- or two-letter symbol for each element. For example, the symbol for hydrogen is H. The symbol for gold is Au.
A molecular formula is an expression of the number and type of atoms that are present in a single molecule of a substance. It represents the actual formula of a molecule. Subscripts after element symbols represent the number of atoms. If there is no subscript, it means one atom is present in the compound.
