Atomic Theory
These two Greek philosophers theorized that if solid matter was repeatedly cut into smaller pieces, the result would be a particle that could not be cut further.
Who are Democritus and Leucippos?
This term describes a row on the periodic table.
What is a period?
This term refers to the actual region of space occupied by an electron in a particular energy level.
What is an orbital?
The metallic character of elements increases in these directions on the periodic table.
What are from right to left, and from top to bottom?
According to Lewis Theory, these types of bonds are formed when one or more electrons is transferred from one atom to another.
What are ionic bonds?
Medieval chemists discovered many methods of separating pure substances while practicing alchemy, attempting to convert base metals into this substance.
What is gold?
The alkaline earth metals are found in this group of the periodic table.
What is group 2?
This is the electron configuration of C.
What is 1s22s22p2?
Atomic radius, the distance between the nucleus and the outermost electron orbital, increases in these directions on the periodic table.
What are from right to left, and from top to bottom?
This term describes the tendency of atoms to form bonds until they are surrounded by 8 valence electrons.
What is the octet rule?
This is the number of protons, neutrons, and electrons in a Ca2+ ion with an atomic mass of 41 amu.
What are 20 protons, 21 neutrons, and 18 electrons?
Unlike non-metals, metals are often excellent conductors of this.
What are heat and electricity?
This is the electron configuration of Cl.
What is 1s22s22p63s23p5?
This term describes the ability of an atom to attract electrons in a chemical bond.
What is electronegativity?
When looking at electronegativity differences, this term would describe the S-O bond in sulfate.
What is a polar covalent bond?
If the isotope distribution of carbon is C-12 (97.00%) and C-13 (3.00%), the mass of the sample would be this.
What is 12.03 g/mol?
Russian chemist Dimitri Mendeleev organized his periodic table based on this quantitative property of atoms.
What is according to atomic mass?
This is the electron configuration of Sn.
What is 1s22s22p63s23p64s23d104p65s24d105p2?
When looking at B, Li, O, and Ne, this element would have the highest ionization energy.
What is Ne?
This is the Lewis structure of BaCl2.
See whiteboard.
In his scattering experiment, Ernest Rutherford disproved Thomson's "plum pudding" model of the atom, discovering that atoms contain this.
What is empty space and a positively-charged nucleus?
Compounds containing ions belonging to this class of metals are often colourful.
What are transition metals?
This term describes a set of orbitals of the same type.
What is a subshell?
Fluorine is highly electronegative due to these properties of the fluorine atom.
What is having a large number of protons to attract electrons and low levels of inter-electron repulsion?
This is the Lewis structure of a phosphate ion (PO43-).
