Everything Flashcards
The mass in grams of one mole of representative particles of a substance
Molar mass
The basic form
Representative particle
Molar concentration
Molarity
A problem-solving strategy that follows unit conversions to arrive at an answer
Dimensional analysis
Deal with how to move lab measurable valve into and out of moles
Mole conversions
Ratios of a substance mass today is volume only depends on type of matter parentheses intensive
Density
Number of protons
Atomic number
Number of protons plus the number of neutrons
Mass number
Adams of the same element with different number of neutrons
Isotopes
Small dents positive region in the center of an Adam
Nucleus
Area outside the nucleus with probability for finding electrons
Electron cloud
Found the neutron
Chadwick
Found that electrons have a negative charge and electrons in their charge our era septa bull and charge to mass ratio is large and plum putting a diagram
JJ Thomson
Discovered alpha and beta radioactivity, discovered the nucleus, discovered the proton, and theory of an empty nucleus experiment gold voile experiment
Rutherford
Oil drop experiment and measure the charge of electrons
Millikan
Force where electrons are kept in orbit
Electromagnetic force
Keeps protons together to form nucleus
Strong forces
Group 1A
Alkali metals
Group 2A
Alkaline earth metals
Group 7A
Halogens (salts)
Group 8A
Noble gases
80% of Adams, solid at room temp, good conductors, give up electrons in reactions
Metals
Properties very but generally are different than metals, usually gain electrons in reactions
Nonmetals
Both properties of metals and nonmetals depending on conditions
Metalloids
Have electrons last added to ādā orbitals
Transition metals
Electrons last added to the F orbital
Inter-transition metals
Made from ions and are typically metal and nonmetal
Ionic compounds
The mass of a substance containing the same number of fundamental units (measurement)
Mole
