The Structure of Matter- Serena Flashcards
(23 cards)
Chemical structure
Arrangement of atoms in something
Chemical bond
Force that holds atoms and ions together
Bond length
Distance between the nuclei and 2 bonded atoms
Bond angle
Formed by 2 bonds at same atom
Hydrogen bond
Oxygen and one hydrogen is stricter to hydrogen
Ionic bond
Formed by the attraction of opposite charged ions
Formula unit
One Na ion and one Cl- ion
Metallic bond
Formed by the attraction of positive charged ions that are metal and electrons around them
Covalent bond
Formed one or more pairs of electrons share an atom
Non polar covalent bond
Electrons are equally shared
Polar covalent bond
Unequal electrons are shared
Polyatomic ion
Ion made up of two or more ions
Empirical formula
Relative numbers and kinds of atoms in a ratio that is simple
Molecular formula
Shows the number and kinds of atoms in a molecule, not the arrangement of atoms.
Organic compound
Compound that contains carbon and excludes carbonates and oxides
Hydrocarbon
Is only made up of carbon and hydrogen atoms
Alkane
When more than three bonded carbon atoms they don’t line up in a row
Alkene
At least one double covalent bond between carbon atoms
Polymers
Large molecule formed by more than five monomers or small units
DNA
Determines the genetic makeup
Carbohydrate
Made up of carbon, hydrogen, and oxygen and provides nutrients to cell
Protein
Made up of one or more chains of amino acids
Amino acid
Contains carboxylate and an amino acid and combines to form proteins
