- organic compound
- a covalently bonded compound that contains carbon
- covalent bond
- A bond whose electrons are shared between atoms
- bond angle
- the angle formed by two bonds to the same atom
- polyatomic ion
- a group of covalently bonded atoms that carries a charge and acts as a unit
- empirical formula
- a chemical formula showing the ratio of elements in a compound rather than the total number of atoms
- protein
- polymer consisting of long chains of amino acids
- chemical structure
- the arrangement of atoms in a substance
- metallic bond
- bond formed by the attraction between positively charged metal ions and electrons in the metal
- carbohydrate
- an essential structural component of living cells and source of energy for animals
- amino acid
- a small molecule that is linked chemically to other amino acids to form proteins
- ionic bond
- a chemical bond in which one atom loses an electron to form a positive ion and the other atom gains to electron to form a negative ion
- bond length
- Distance between two nuclei in a chemical bond.
- molecular formula
- tells how many atoms are in one molecule of a compound
- chemical bond
- an interaction that holds atoms or ions together
- polymer
- large organic molecule formed by combining many smaller molecules (monomers) in a regular pattern
