Unit 1
What's the difference between kinetic and potential energy?
The difference between kinetic and potential energy is that potential energy is stored energy and kinetic energy is moving energy.
What is an atom?
An atom is the smallest particle of an element.
What is a period in the periodic table?
What are cation's and anion's?
Cations are positively charged ions, while anions are negatively charged ions.
What is a compound?
A compound is 2 or more elements bonded together.
What is combustion?
Combustion is a chemical reaction which reacts to oxygen, producing energy in the form of heat and light.
The atomic number is equal to the number of __.
Protons
What's a valence electron?
Valence electrons are electrons found in the outer s/p orbitals, which are used to form chemical bonds.
What is a covalent compound?
A poly-atomic ion is a group of atoms covalently (non-metals) bonded together.
What is the Law of Conservation of Energy?
The Law of Conservation of Energy is the law that energy cannot be created nor destroyed.
What's the charges on protons, neutrons, and electrons?
Protons have a positive charge, neutrons have a neutral charge, and electrons have a negative charge.
What's a Lewis Dot structure?
A Lewis Dot structure is a drawing which the element symbol is written with the number of valence electrons surrounding it.
Octet rule is the rule that an atom can only have 8 valence electrons.
Name this covalent compound: N20
Dinitrogen Oxide
How is heat transferred within the layers of the Earth?
Heat is transferred within the layers of the Earth using geothermal energy.
What's an isotope?
An isotope is an atom that have the same number of protons and different numbers of neutrons.
Where are non-metals located?
Non-metals are located on the right side of the periodic table.
What's the difference between Polar and Non-Polar covalent bonds?
The difference between covalent Polar and Non-Polar bonds is that covalent Polar bonds share valence electrons unevenly while covalent Non-Polar bonds share valence electrons evenly.
Whats is the subscript for in a chemical formula?
The # of that element.
What's the relationship between tectonic movement, earthquakes, geysers, and volcanoes?
What's the difference between the Quantum model and the Bohr model?
Bohr's model states that the electrons to revolve in circular orbits while the Quantum model removes the possibility of a definite electron pathway and finds the electrons in a defined space.
What is electron affinity?
What is solubility and conductivity?
Conductivity is the measure of the ease at which an electric charge or heat can pass through a material. Solubility is a property referring to the ability for a given substance, the solute, to dissolve in a solvent.
What's the difference between a binary and ternary elements?
Ternary ionic compounds contain three elements, at least one metal and one nonmetal. are ternary ionic compounds. Binary molecular compounds contain two elements and both are nonmetals.
