Modeling Pt. 2
Activity that is central to scientific inquiry.
Observation
The study of the composition and structure of matter.
Chemistry
The number of protons in atoms of each element.
Atomic Number
These kind of scientists aim to turn low-value materials into high-value materials.
Alchemists
Anything that occupies space and has mass.
Matter
The S.I. fundamental unit of mass.
Kilogram (kg)
Most common state of matter.
Plasma
Subatomic particle with no electrical charge.
Neutrons
Rows on the periodic table.
Periods
This branch of science is good at explaining the motion and energy of things like cars and planets.
Classical Physics
Color and texture are examples of this kind of data.
Qualitative Data
Space enclosed or occupied by an object.
Volume
Describes the total number of protons and neutrons in an isotope; written as a whole number.
Mass Number
This group of elements are mainly used for lighting, optics, and medicine.
Noble Gases
When thinking of the the symbols used to represent different elements: H2O, NaCl, and C6H12O6 are all exmaples of what?
Chemical Formula
The degree of exactness of a measurement.
Precision
Pure substance containing atoms that have the same atomic number.
Element
Ions that have an excess positive charge.
Cations
Elements found in groups 3-12; often used in alloys such as sterling silver or steel.
Transition Metals
Branch of physics that explores the behavior of matter and energy at subatomic levels.
Quantum Mechanics
Model that explains a related set of phenomena.
Scientific Theory
Measure of a fluid's resistance to flowing.
Viscosity
This scientist is credited with creating the first modern atomic model.
John Dalton
The measure of an element's ability to attract and hold electrons when bonded to other atoms.
Electronegativity
The S.I. unit for temperature.
Kelvin (k)
