Chemistry Periodic Table Quiz

Ionization Energy

Ionization Energy

The amount of energy needed to remove an electron from an atom; (down a group: decreases, across a period: increases)

Electronegativity

A measure of the ability of an atom's nucleus to attract electrons from a different atom within a covalent bond; (down a group: decreases, across a period: increases)

Atomic Radius

The distance from the nucleus to the outer shell of an atom (down a group: increases, across a period: decreases)

Ionic Radius

The distance between the nucleus of an ion and the outermost shell of the ion; (down a group: increases, across a period: decreases)

Coulombic Attraction

Natural attraction of protons and electrons

Nuclear Charge

The total charge of all the protons in the nucleus

Shielding Effect

When the electron and the nucleus in an atom have a decrease in attraction which changes the nuclear charge

Alkali Metals

Group 1 on the Periodic Table (Not including Hydrogen)

Alkaline Earth Metals

Group 2 on the Periodic Table

Transition Metals

Group 3 (First two) and Groups 4-12 on the Periodic Table

Inner Transition Metals

F-Block (Including bottom 2 of Group 3) on the Periodic Table

Nonmetals

No metallic properties; To the right of the staircase

Metalloids

Some metallic properties; Touching the staircase

Metals

Metallic properties; To the left of the staircase

Halogens

Group 17 on the Periodic Table

Noble Gasses

Group 18 on the Periodic Table

Conductivity

The measure of the ease at which an electric charge or heat can pass through a material

Malleable

Able to be hammered or pressed permanently out of shape without breaking or cracking

Ductile

Able to be drawn out into a thin wire

Luster

The quality of reflecting light from a metal's surface

Semiconductor

Substances that sometimes conduct electicity (Properties between a conductor and a (insulator) non-conductor)

Inert

Having little or no ability to react

Melting Point

The temperature at which a given solid will melt

Boiling Point

The temperature at which a given liquid starts to change into steam or vapor

Staircase

Separates the metals from the non-metals; The metalloids are located on the staircase

Periodic

Relating to the periodic table of the elements or the pattern of chemical properties that underlies it.

Carbon Group

Group 14 on the Periodic Table

Nitrogen Group

Group 15 on the Periodic Table

Oxygen Group

Group 16 on the Periodic Table
