100
“happening at regular intervals.”
What is Periodic
100
Has a negative charge
What is an electron
100
is the joining of atoms to form new substances.
What is Chemical Bonding
100
is a process in which one or more substances change to make one or more new substances. The chemical and physical properties of the new substances differ from those of the original substances.
What is a Chemical Reaction
100
____ P4 + ____ O2 → ____ P2O3 (Balance this equation)
1 P4 + 3 O2 → 2 P2O3
200
Represents the number of Protons in an atom
What is the Atomic Number
200
Where the Protons and Neutrons reside
What is the Nucleus
200
An electron in the outermost energy level of an atom
What is a Valence Electron?
200
is a shorthand way to use chemical symbols and numbers to represent a substance.
What is chemical formula
200
____ GaF3 + ____ Cs → ____ CsF + ____ Ga (Balance this)
1 GaF3 + 3 Cs → 3 CsF + 1 Ga
300
The physical and chemical properties of elements in a row follow a repeating, or periodic, pattern as you move across the period.
What is a period
300
are atoms that have the same number of protons but have different numbers of neutrons.
What is an Isotope
300
a bond that forms when electrons are transferred from one atom to another atom.
What is an Ionic Bond
300
CCl4.
What is Carbon TetraChloride
300
____ Pb(OH)2 + ____ HCl → ____ H2O + ____ PbCl2 (Balance this)
1 Pb(OH)2 + 2 HCl → 2 H2O + 1 PbCl2
400
metals have two outer-level electrons.
What is Alkaline Earth metals
400
is the weighted average of the masses of all the naturally occurring isotopes of that element.
What is Atomic Mass
400
are charged particles that form when atoms gain or lose electrons.
What is an Ion?
400
Calcium oxide
What is C2O2
400
____ AlBr3 + ____ K2SO4 → ____ KBr + ____ Al2(SO4)3 (Balance this)
2 AlBr3 + 3 K2SO4 → 6 KBr + 1 Al2(SO4)3
500
found to the right of the zigzag line on the periodic table
What is a non metal
500
The SI unit used to express the masses of particles in atoms
What is Atomic Mass Unit (amu)
500
forms when atoms share one or more pairs of electrons.
What is a Covalent Bond
500
Instead of changing words and sentences into other languages to describe reactions, chemists use these.
What is Chemical equation
500
____ Na3PO4 + ____ CaCl2 → ____ NaCl + ____ Ca3(PO4)2 (Balance this)
2 Na3PO4 + 3 CaCl2 → 6 NaCl + 1 Ca3(PO4)2
