|
Term
|
|
The number of protons in the nucleus of an atom, which determines the chemical properties of an element and its place in the periodic table.
|
|
Atomic Number
|
|
It is approximately equivalent to the number of protons and neutrons in the atom.
|
|
Atomic Mass
|
|
An atom or molecule with a net electric charge due to the loss or gain of one or more electrons.
|
|
Ion
|
|
The number of times a point on a wave passes a fixed reference point in one second.
|
|
Frequency
|
|
The distance between any given point and the same point in the next wave cycle.
|
|
Wavelength
|
|
Energy that moves from one place to another in a form that can be described as waves or particles.
|
|
Radiation
|
|
The smallest and the fundamental particle of electromagnetic radiation.
|
|
Photons
|
|
This rule states that in the ground state of an atom or ion, electrons first fill sub-shells of the lowest available energy, then fill sub-shells of higher energy
|
|
Afbau Principle
|
|
This principle states that no two electrons in the same atom can have identical values for all four of their quantum numbers.
|
|
Pauli Exclusion Principle
|
|
This rule states that every orbital in a sub-shell is singly occupied with one electron before any one orbital is doubly occupied and all electrons in singly occupied orbitals have the same spin.
|
|
Hund's Rule
|
|
This is a reaction in which the nucleus of an atom splits into two or more smaller nuclei.
|
|
Nuclear Fission
|
|
This is the process by which two light atomic nuclei combine to form a single heavier one while releasing massive amounts of energy.
|
|
Nuclear Fusion
|
|
In this experiment, electrons are accelerated from one end of the tube to the other using an electric field.
|
|
CRT experiment
|
|
This is the property exhibited by certain types of matter of emitting energy and subatomic particles spontaneously.
|
|
Radioactivty
|
|
This is the quantitative property that is transferred to a body or to a physical system, recognizable in the performance of work and in the form of heat and light.
|
|
Energy
|
|
The smallest unit of matter, discovered by Democritus.
|
|
Atom
|
|
A series of colored lines with dark spaces in between.
|
|
Line Spectra
|
|
This is a function describing the location and wave-like behavior of an electron in an atom.
|
|
Orbitals
|
|
Fixed distances from the nucleus of an atom where electrons may be found.
|
|
Energy levels
|
|
Energies associated with electrons
|
|
Energy sublevels
|
|
A weapon with great explosive power that results from the sudden release of energy upon the splitting, or fission, of the nuclei of a heavy element such as plutonium or uranium.
|
|
Atomic Bomb
|
|
The energy that is released through a nuclear reaction or radioactive decay process.
|
|
Atomic Energy
|
|
A fundamental physical constant that is the speed at which electromagnetic radiation travels in a vacuum and that has a value of 299,792,458 meters per second.
|
|
Speed of Light
|
|
A great Greek philosopher that came up with the concept of atoms.
|
|
Democritus
|
|
He devised a concept of particle repulsion that is indirectly related to the hydrophobic effect.
|
|
Benjamin Franklin
|
|
He succeeded in precisely determining the magnitude of the electron's charge.
|
|
Robert Milikan
|
|
He proved the existence of neutrons – elementary particles devoid of any electrical charge.
|
|
James Chadwick
|
|
He introduced the idea that particles, such as electrons, could be described not only as particles but also as waves.
|
|
Louis Debroglie
|
|
He discovered the electron and then went on to propose a model for the structure of the atom.
|
|
J.J. Thomson
|
|
He proposed a theory for the hydrogen atom.
|
|
Neils Bohr
|
|
He developed a powerful model of the atom.
|
|
Erwin Schrodinger
|
|
She discovered radium and polonium, and made huge contribution to finding treatments for cancer.
|
|
Marie Curie
|
|
His atomic theory suggested that all matter was comprised of indivisible and indestructible atoms with distinct masses and properties.
|
|
John Dalton
|
|
He demonstrated that there were at least two distinct types of radiation: alpha radiation and beta radiation.
|
|
Ernest Rutherford
|
|
His work established the concept of atomic number and helped reveal the structure of the atom.
|
|
Henry Moseley
|
|
While studying the molecular theory of liquids, he tried to explain the motion of particles through Brownian motion. This theory explains the random movement of particles in a fluid or gas.
|
|
Albert Einstein
|
|
He formulated a type of quantum mechanics based on matrices.
|
|
Werner Heisenberg
|
|
He is credited with discovering the element thallium, announced in 1861, with the help of spectroscopy.
|
|
William Crooke
|
|
He helped discover the radioactive element protactinium.
|
|
Leis Meitner
|
Some answers are doubled, like 'particles suggested by Democritus - atoms' and 'Person who suggested atoms - Democritus"
Other than that, the name of the quiz suggests it's terminology but there are many scientists' names mixed in. You might change the quiz name or separate it into two quizzes, one for terminology and the other for famous chemists.
