Now you see it, Now you don't (Physical vs. Chemical Change)
This type of change alters the form or appearance of a substance but does not create a new substance.
What is Physical change?
Being a heavily modified version of Rutherford's atomic model many find it Bohring.
What is Bohr's Atomic Model?
There's certainly no cons to these positive little guys.
What is a Proton?
This property describes how shiny a material is because some substances just love the spotlight.
What is luster?
This experiment involves a cat and illustrates the peculiar nature of quantum superposition. It also shows how cruel people can be to cats
What is Schrödinger's cat?
Rust forming on a metal surface is an example of this change.
What is a Chemical change?
This scientist’s "plum pudding model" suggested that atoms consisted of a positively charged "soup" with negative electrons embedded inside.
Who is Thomson?
Electrons move around the nucleus in these regions, following quantum rules instead of predictable paths.
What are Orbitals?
Unlike a bad haircut, this property allows a substance to be hammered into thin sheets without breaking.
What is malleability?
Einstein described this invisible "fabric" as being warped by massive objects, causing gravity.
What is space-time?
Dissolving salt in water is considered this type of change
What is a Physical change?
This scientist deserves a gold star for his experiment that helped discover the nucleus and proposed that atoms have a dense, positively charged center.
Who is Rutherford?
The number of protons in an atom’s nucleus determines this, defining its identity on the periodic table.
What is the Atomic Number?
This chemical property measures how well a substance reacts with oxygen it's why iron ends up with a flaky, red-orange makeover.
What is reactivity?
A hypothetical passage through space-time, this concept might allow instantaneous travel between distant points.
What is a wormhole?
Burning wood results in ashes and smoke
What is a chemical change?
This old man is the father of it all, coming up with the term "atomos".
Who is Democritus?
Something plays this important role in the nucleus, preventing protons from repelling each other.
What is a neutron?
If a material snaps easily when stressed, it has this property think of dry spaghetti versus a cooked noodle.
What is brittleness?
Scientists believe most of the universe is made up of this mysterious substance that does not emit or absorb light.
What is Dark Matter?
Ice melting in a glass is an example of this type of change
What is a physical change?
Let's hope the cat doesn't have your tongue, which person helped develop a mathematical equation describing the path of electrons in specific energy levels in terms of probability?
Scientists use this model to predict the likely locations of electrons, acknowledging their unpredictable behavior.
What is the quantum mechanical model?
This type of chemical property is why some substances can set off fireworks literally!
What is flammability?
This theoretical limit, named after a physicist, is the maximum amount of information that can be contained within a given region of space.
What is the Bekenstein bound?
