Periodic Law Vocab 5

QuestionAnswer
Periodic table an arrangement of the elements in order of their atomic numbers so that elements with similar properties fall in the same column, or group.
Noble Gas a Group 18 element (helium, neon, argon, krypton, xenon, and radon).
Lanthanides one of the 14 elements with atomic numbers from 58 (cerium, Ce) to 71 (lutetium, Lu).
Actinides one of the 14 elements with atomic numbers from 90 (thorium, Th) to 103 (lawrencium, Lr).
Periodicity regular variations of properties of elements with atomic number (and position in the periodic table).
Period a horizontal row of elements in the periodic table.
Family a vertical column of the periodic table.
Series a horizontal row of the periodic table.
Group a vertical column of the periodic table.
s-block elements elements in Group 1 and 2, excluding H.
p-block elements elements in Group 13 through 18, excluding He.
d-block metals elements in Groups 3 through 12 with atomic numbers 21-30, 39-48, 57-80, and 89-112.
f-block metals elements with atomic numbers 58-71, and 90-103.
Alkali metals one of the elements of Group 1 of the periodic table (lithium, sodium, potassium, rubidium, cesium, and francium).
Alkaline Earth metals one of the elements of Group 2 of the periodic table (beryllium, magnesium, calcium, strontium, barium, and radium).
metal an element that is a good conductor of heat and electricity.
transition metals one of the d-block elements; has typical metallic properties.
main-group or representative elements an element in the s-block or p-block.
halogens one of the elements of Group 17 (fluorine, chlorine, bromine, iodine, and astatine).
atomic radius one-half the distance between the nuclei of identical atoms that are bonded together.
bonding radius the radius of the n=1 orbital in hydrogen.
ionization energy the energy required to remove one electron from a neutral atom of an element.
electron affinity the energy change that occurs when an electron is acquired by a neutral atom.
valance electron an electron that is available to be lost, gained, or shared in the formation of chemical compounds.
cation a positive ion.
anion a negative ion.
ion an atom or group of bonded atoms that has a positive or negative charge.
atomic mass unit a unit of mass that is exactly 1/12 the mass of carbon-12 atom, or 1.660540x10-27 kg
nonmetal an element that is a poor conductor of heat and electricity.
isotope atoms of the same element that have different masses.
shielding effect electrons in filled sets of s, p orbitals between the nucleus and outer shell electrons shield the outer shell electrons somewhat from the effect of protons in the nucleus; also called screening effect.

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.
