The Atom Climate Change Periodic Table Chemical Bonds Chemical and Physical changes
100
What is an atom
An incredibly small, fundamental unit of matter consisting of subatomic particles such as protons, neutrons, and electrons.
100
What is climate change
Changes in the earth’s climate system that remain in place for an extended period of time.
100
What is the periodic table
A chart in which all known elements are listed in order of atomic number.
100
What is a chemical bond
The force of attraction between two atoms that holds them together within a compound
100
What is a physical change
A change in a substance's physical properties, but no change in its chemical identity.
200
What is the atomic mass
The mass of an element's atoms; listed on the periodic table as an average value based on the relative abundance of the elements isotopes.
200
What are some of Earth’s vital signs of climate change?
Sea level rise, global surface temperature, forest coverage, and ice sheet coverage.
200
What is an atomic symbol
An abbreviation for an element or atom.
200
What is an ionic bond
A chemical bond in which atoms are not shared equally and one atom takes an electron or electrons from the other atom(s) in the compound.
200
What is a chemical change
The formation of a new substance by the rearrangement of the atoms of the original materials.
300
What is the shell model
A physical model of the atom in which the atom is a series of shells, each of which can hold a certain amount of electrons. The atom always wants to be full.
300
What is the definition of Earth’s vital signs?
Anything that alters Earth’s energy budget in a huge way
300
What is a group
A vertical column in the periodic table.
300
What is a covalent bond
A chemical bond in which electrons are shared equally by the atoms in the compound.
300
What is the signs of a chemical change
Color change, generation of gas, precipitation forms, and temperature change.
400
What is ionization
The process of removing an electron from the electron cloud or add one, giving the atom a positive or negative charge.
400
What is Earth's energy budget
The balance between the energy that the Earth absorbs and the energy that is released from Earth
400
What is a period
A horizontal row in the periodic table
400
What is electronegativity
The ability of a bonded atom to pull shared atoms
400
What is sublimation
The transformation of a solid to a gas.
500
What is quantum hypothesis
Max Planck’s hypothesis that warm bodies emit radiant energy in discrete bundles called quanta
500
What is why CO2 concentration is considered one of Earth’s vital signs
An overabundance of CO2 has been released into the air, causing it to become trapped in the atmosphere, which blocks energy from escaping the Earth and has resulted in warmer temperatures and acidic oceans.
500
What is the noble gases
The final column in the periodic table.
500
What is determines the bond type?
The difference in electronegativity between the atoms in the compound
500
What is deposition
The transformation of a gas to a solid.
