Science of Chemistry
This branch of chemistry studies compounds that contain carbon.
What is organic chemistry?
What is an element?
Positive particle in the nucleus of an atom.
What is a proton?
Name given to elements in Group 1.
What are alkali metals?
Bonding that results from electrical attraction between cations and anions.
What is ionic bonding?
This branch of chemistry studies properties and changes of matter.
What is physical chemistry?
Substance that can be broken down into more simple substances.
What is a compound?
This physicist conducted the famous gold-foil experiment.
Who is Rutherford?
Most unreactive group of elements, due to their filled up valence shell.
What are noble gases?
Sharing of electron pairs between atoms in a molecule.
What is covalent bonding?
This branch of chemistry studies substances and processes in living things.
What is biochemistry?
Property that depends on amount of matter present.
What is an extensive property?
Represents the number of protons in an atom of a specific element.
What is the atomic number?
Letter given to orbital shells for which l = 2.
What is d?
Covalent bond in which electrons are more attracted to one atom than the other.
What is polar-covalent?
This branch of chemistry tries to identify components and compositions of materials.
What is analytical chemistry?
Property that can be observed or measured without changing the identity of the substance.
What is a physical property?
Atoms of the same element that differ in their number of neutrons.
What are isotopes?
Energy needed to remove an electron from an atom.
What is ionization energy?
A covalent bond in which two pairs of electrons are shared.
What is a double bond?
This branch of chemistry uses mathematics and computers to observe and predict chemical behavior.
What is theoretical chemistry?
State of matter that has definite volume but indefinite shape.
What is liquid?
Number of particles in a mole of matter, corresponding to 6.022 X 1023 particles.
What is Avogadro's number?
Tendency of an element to attract electrons from other atoms in a molecule. Fluorine has the highest one.
What is electronegativity?
What is Lewis notation?
