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
