Vocabulary
The gathering of information using senses or with the aid of instruments
Observation
A well-tested description of one phenomenon in the natural world that often includes mathematical terms
Scientific Law
Atomic #: 1
Symbol: H
Avg atomic mass: 1.01
Hydrogen
All conversion factors are equal to what number
1
This is a simplified representation (physical, mathematical, or conceptual) of a real-world object, system, or phenomenon, used by scientists to understand, explain, visualize, and predict complex things that are too big, small, fast, slow, or abstract to study directly, acting as essential tools for research, communication, and theory building.
Scientific Model
An atom or a group of atoms that has a positive or negative charge
Ion
theory of matter proposes that all matter is made of tiny particles (atoms/molecules) in constant, random motion, with their energy and spacing determining the state (solid, liquid, gas).
Kinetic Theory of Matter
Atomic #: 8
Symbol: O
Avg atomic mass: 16.0
Oxygen
What is calculated in this equation (s = d/t)
Speed
Also known as the Plum Pudding Model, this model propose that atoms are spheres of uniformly distributed positive charge with negatively charged electrons embedded within them, like plums in a pudding or seeds in a watermelon, making the atom electrically neutral overall.
Thomson's Atomic Model
The change in an object's velocity over time
Acceleration
An object in motion (or at rest)will stay in motion (or at rest) until it is acted upon by an unbalanced force
Newton's First Law of Motion
Atomic #: 11
Symbol: Na
Avg atomic mass: 23.0
Sodium
What is calculated in this equation: a = (Vf - Vi) / t
Acceleration
This Model proposed that atoms have a tiny, dense, positively charged nucleus containing most of the mass, with light, negatively charged electrons orbiting it in vast empty space, much like planets around the sun.
Rutherford's atomic model
The tendency of an object to resist changes in its velocity
Inertia
Theory based on two core principles: the laws of physics are the same for all non-accelerating observers, and the speed of light in a vacuum is constant for everyone, regardless of their motion.
E = mc²
Einstein's Theory of Special Relativity
Atomic #: 33
Symbol: As
Avg atomic mass: 74.9
Arsenic
weight
This model describes the atom as a central nucleus with electrons orbiting in fixed, quantized energy levels (shells), much like planets around the sun, but held by electrostatic force, not gravity.
Bohr's Atomic model
The Product of Force and the distance the object moves
Work
A theory that states all matter is made of particles called atoms, and two or more of these from different elements can join together to form compounds in chemical reaction
Dalton's Atomic Theory
Atomic #: 78
Symbol: Pt
Avg atomic mass: 195.1
Platinum
m x g x h =
Potential Energy
This model describes atoms with a dense nucleus surrounded by fuzzy, probability-based regions (orbitals) where electrons are likely to be, rather than fixed paths.
The electron cloud/ Quantum mechanical model
