General Chemistry

Question 1

Atomic Theory

Answer 1

All matter consists of indivisible atoms Atoms of the same element are identical Chemical reactions are the result of atoms recombining

Question 2

Ionic Compounds

Answer 2

Contain a metal and a nonmetal Eg. KCl (Potassium Chloride) List Cation first and Anion second -metal keeps its name followed by the nonmetal with the -ide suffix -no prefixes

Question 3

Molecular Compounds

Answer 3

Contain two nonmetals - named in order of elecronegitivity - Exception C is first - Exception H is after N - Suffix -ide is added to the end of the second element - Prefixes are used (mono, di, tri, tetra, penta)

Question 31

Covalent Bonds

Answer 31

- formed between 2 nonmetals by sharing valence electrons Nonpolar bonds - occur when 2 atoms of similar electronegativity join together Polar Bonds - occur when there is a difference is electronegativity

Question 32

Ionic Bonds

Answer 32

Form when the electronegativity diff is greater than 1.7 - Form between metals and nonmetals - Stronger than covalent bonds - electrons completly transfered from metal to nonmetal

Question 33

Metalic Bonds

Answer 33

Metal atoms joining together

Question 34

Ionic Substances are usually...

Answer 34

solids at room temperature, have high melting points, are water soluable

Question 35

Intermolecular Forces in order from least strength to most strength

Answer 35

London dispursion Dipole Dipole Hydrogen Bonds Ion-dipole forces Ionic interactions

Question 36

London Dispursion Forces

Answer 36

- Weakest intermolecular force - Present between any pair of molecules - Occur when temporary dipoles arise by chance

Question 37

Dipole Dipole Interactions

Answer 37

-Occur between stable dipoles
