Chapter 5 Structure Of Matter Flashcards
Holds ions or atoms together with and attractive force.
chemical bond
What is a chemical structure?The way the atoms in a substance are arranged.
chemical structure
Gives the distance between the two bonded atoms and the nuclei.
bond length
Two bones to the same atom form an angle.
Bond angles
A bond is formed by the attraction between oppositely charged ions.
Ionic bond
The attraction between positively charged metal ions and the electrons around them form a bond.
Metallic bond
Attractions between water molecules
Hydrogen bond
When atoms share one or more pairs of electrons a bond is formed.
Covalent bond
Ion that is made of tow or more atoms
Polyatomic ion
Na+ ion and Cl- make up NaCl- formula unit
Formula unit
In which electrons are shared equally in a covalent bond.
Nonpolar covalent bond
In which electrons are shared unequally in a covalent bond.
Polar covalent bond
The makeup of a compound in terms of the kinds of atoms in simplest ratio and numbers.
Empirical formula
A chemical formula that doesn’t show the arrangement of the molecule, but shows the number of the kind of atom.
Molecular formula
Compound that has a covalent bond that contains carbon.
Organic compound
Formed by more than five monomers and is a big molecule.
Polymer
Gives nutrients to the cells in living things is any organic compound that is made from carbon, hydrogen and oxygen.
Carbohydrate
Also an organic compound made when amino group and a corboxyl combine
Protein
Decides your entire genetic makeup
DNA
Any molecule of of 20 different organic ones that contain an amino group and a carboxyl that form proteins when put together.
Amino acid
Compound made of carbon and hydrogen
Hydrocarbon
Hydrocarbons with one single covalent bond C-C
Alkane
Hydrocarbons with one double covalent bonds C=C
Alkene
