Protons, Neutrons, oh my!
Protons determine the what of an element?
Identity
What is the distance between two crests called?
Wavelength
Mr. Snyder says he feels like a wave — sometimes up, sometimes down. What’s the highest and lowest part of a wave called?
The crest and the trough
What gives seawater its salty taste?
Dissolved salts, mainly sodium chloride
What does each box on the periodic table represent?
An element
What subatomic particle has no charge?
Neutron
What type of wave needs a medium to travel?
Mechanical wave
Mr. Snyder claims his “drip” is an example of surface tension. Why is that actually correct?
Because surface tension allows water to bead up and “drip” instead of spreading flat.
What happens to the density of seawater when salinity increases?
Density increases
What does the atomic mass mostly come from?
Protons + neutrons
What is the charge of a neutral atom
0
What kind of wave is light?
Electromagnetic
Mr. Snyder said his jokes “sublimate” straight from solid to awesome. What’s sublimation?
When a solid changes directly to a gas without becoming a liquid.
How does temperature affect seawater density?
Colder water is denser than warmer water
What is a molecule?
a group of two or more atoms held together by chemical bonds, representing the smallest unit of a chemical substance that retains its properties
How is the atomic mass of an element calculated?
It’s the weighted average of all the elements’ isotopes, based on their mass and natural abundance.
What is the difference between Mechanical and Electromagnetic waves?
Mechanical waves require a medium (like air, water, or solids) to travel, while electromagnetic waves do not and can travel through a vacuum.
Mr. Snyder said he’s made of “pure awesomenium.” What actually makes up every element in the universe?
Atoms
What process increases salinity in ocean water?
Evaporation
What determines the identity of an element?
The number of Protons
An atom has 11 protons and 10 electrons. What is its overall charge, and what element is it?
+1 charge
What’s the formula to calculate wave speed?
Speed = wavelength × frequency
This teacher is referred to as a wiggly worm, and is less sigma than Mr. Snyder.
Who is Mr. DELANEY AKA DELAMO
DAILY DOUBLE!!!!!
As sunlight travels deeper into seawater, some colors disappear first while others reach farther.
Which colors of light are absorbed quickest, which penetrate deepest, and why does this matter for marine life?
Quickest: Red, Orange
Deepest: Blue Travel deepest
This matters because many photosynthetic organisms and animal pigments depend on the available light — for example, coral symbionts use blue-green light for photosynthesis, and deep-sea animals appear red or black since red light doesn’t reach them.
What are atoms of the same element with different numbers of neutrons called?
Isotopes
