Atoms
The modern view of how electrons move around in an atom.
What is the quantum-mechanical model?
This is the female part of an angiosperm flower.
What is the carpel?
These gasses occupy the last column on the period table.
What are noble gasses?
This element's most common isotope has a mass of 28.
What is Si?
A force that acts on an object moving in a circle directed toward the center of the circle.
This instrument measures the mass of individual atoms or molecules.
What is a mass spectrograph?
This is the chemical equation for photosynthesis.
What is 6CO2 + 6H20 ---> C6H12O6 + 6O2
The number of neutrons in the nucleus doesn't affect which element the atom belongs to, but it does affect this.
What is the mass of the element?
This is where a fluorine (F) atom puts its electrons.
These bacteria are designed to aid in a process that convers the nitrogen in the air into ammonia.
What is nitrogen-fixing bacteria?
Atoms are made of clouds, typically represented with these electron shapes.
What is an s and p orbital?
In light, the amount of this determines its color.
What is radiant energy?
The number of this determines the element, and the different numbers of neutrons cause atoms to have different masses.
What are protons?
Elements are very stable when these are filled.
What are their largest s and p orbitals?
This bacteria, found in water, is essential for life and does an estimated 20% of all the photosynthesis that takes place on the planet.
What is cyanobacteria?
Light is energy, and if an electron emits light, it loses this.
What is energy?
This is a kind of mutualism between the roots of a plant and a fungus.
What is mycorrhiza?
An ionic compound must have at least one of these.
What is a metal and a nonmetal.
This is a compound with the same chemical formula but different arrangements of atoms, which leads to different chemical properties.
What is an isomer?
This is a hypothesis that has been tested with a significant amount of data.
What is a theory?
The average mass of atoms that make up an element.
What is the atomic mass?
These prokaryotic cells thrive in hot water.
What are thermophilic bacteria?
These four names are chemicals that form base pairs in DNA. Adenine, Thymine, Guanine, and Cytosine.
What are Adenine, Thymine, Guanine, and Cytosine?
These gases are already in their lowest energy state.
What are noble gases?
This law states that when matter undergoes a change, the total amount of matter cannot change, regardless of what changes occur in the actual substances being studied.
What is the Law of Mass Conservation?
