Chemistry Vocab01

Atoms

TermDefinition
Electronegativity A property of an atom which increases with its tendency to attract the electrons of a bond.
Atomic Radius the distance from the atomic nucleus to the outermost stable electron orbital in a atom at equilibrium
Metal A solid material that is typically hard, shiny, malleable, fusible, and ductile, with good electrical and thermal conductivity.
Nonmetal One of the elements which do not exhibit metallic properties, generally located in the upper righthand corner of the Periodic Table.
Metalloid an element with properties intermediate between those of a metal and nonmetal
Halogen Halogens are reactive nonmetals having seven valence electrons.
Alkali Metals are very reactive chemical species which readily lose their one valence electron to form ionic compounds with nonmetals.
Alkaline Earth Metals any of the divalent electropositive metals beryllium, magnesium, calcium, strontium, barium, and radium
Groups A section is which elements share similar chemical properties
Period Rows of elements
First Ionization Energy the energy required to remove an electron from a gaseous atom or ion
Re activity responsive to stimulation
Bohr Model the structure of the atom, according to which electrons move in orbits around the nucleus
Shell A set of electron orbitals with the same principal quantum number.
Orbital An energy state in the atomic model which describes where an electron will likely be.
Primary Quantum Number A number used when describing the energy levels available to atoms and molecules.
Angular Momentum Quantum Number the quantum number associated with the angular momentum of an atomic electron.
Magnetic Quantum Number the quantum number that identifies different orbitals within a subshell
Electron Spin A property of an electron that is loosely related to its spin about an axis
Hunds Rule every orbital in a subshell is singly occupied with one electron before any one orbital is doubly occupied
Pauli Exclusion Principle no two electrons can have the identical quantum mechanical state in the same atom.

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
