Basic Chemistry
100
Typically atoms are neutrally charges in the elements in the Periodic Table; however, many of the non-metals tend to gain electrons to become what?
What are anions?
100
These are the electrons found in the outermost energy shell of an atom that are involved in chemical reactions.
What are valence electrons?
100
These numbers describe the orbital occupied by an electron.
What are Quantum Numbers?
100
This is how many grams of water are found in one mole of pure water.
What is 18 g/mol water.
100
This is anything that takes up space (with mass and inertia) that is composed of atoms.
What is matter?
200
He is the man credited with organizing the very first intact Period Table (and Periodic Law).
Who is Mendeleev?
200
The elements in Group/Family VIIA have this many valence electrons.
What is 7?
200
This law dictates that no two electrons in the same atom may have the same found Quantum Numbers.
What is the Pauli Exclusion Principle?
200
This type of bond occurs between metals and nonmetals, and involves the donating of valence electrons for bonding.
What is an ionic bond?
200
Substances made up of two or more elements.
What are compounds?
300
In the Periodic Table, the rows are called these and the columns are called these.
What are Periods and Groups/Families, respectively?
300
This type of formula describes the kinds of elements found in a compound and the numbers of their atoms.
What is a Molecular Formula?
300
While Mendeleev's Periodic Law allows for us to predict the properties of elements in the Periodic Table, this theory explains why this is possible.
What is Quantum Mechanics?
300
This type of bond between atoms involves the sharing of valence electrons to satisfy the outermost energy shell octet rule.
What is a covalent bond?
300
This is the type of Chemistry that deals with molecules that have Carbon (C) atoms at the core of their structure.
What is Organic Chemistry?
400
Roughly 75% of elements are of this type.
What are metals?
400
The mass of one mole of atoms is called this.
What is the molar mass?
400
This element has the electron configuration of 1s2, 2s2, 2p6, 3s2, 3p4.
What is Sulfur (S)?
400
This is the most reactive group of nonmetals in the Periodic Table.
What are the halogens.
400
This man proposed the very first theory of the atom.
Who is Democritus?
500
This class of elements are found in Group VIIA.
What are halogens?
500
The name for this constant: 6.022x10^23 1/mol
What is Avogadro's Constant?
500
This rule dictates that orbitals of the same energy subshell/sublevel are each occupied by one electron before any pairing occurs.
What is Hund's Rule?
500
Three lines in a structural formula depict the sharing/donating of this many valence electrons.
What is 6?
500
This is the smallest particle of an element that possesses all of the characteristics of a specific element.
What is the atom?
