Classification of Elements and the Periodic Table

Practice flashcards covering the basics of subatomic particles, element classifications, and the horizontal and vertical structures of the periodic table.

Proton

The subatomic particle that determines the identity of an element.

Neutron

The subatomic particle that has no electricad charge.

Electron

The subatomic particle that, in a neutral atom, exists in a quantity equal to the number of proton.

Metals

A classification of elements that are shiny, malleable, ductile, and good conductors of heat / electric current, such as $Cu$, $Al$, $Ag$, and $Au$.

Non-Metals

A classification of elements that are dull, unmalleable, and poor conductors of heat / electric current, such as Carbon, Chlorine, and Hydrogen.

Metalloids

Elements with properties of both metal and nonmetals, which can be shiny/dull, malleable/ductile, and good/poor conductors.

Period

Each of the $7$ horizontal rows of the table; they represent the number of energy levels or electron shells present in an atom.

Family or Group

Each of the $18$ vertical columns of the table; elements in the same group have the same number of valence electrons and similar chemical properties.

Calcium ($Ca$)

The specific element located at Group $2$, Period $4$.

Tin ($Sn$)

The specific element located at Group $14$, Period $5$.

Cesium ($Cs$)

The specific element located at Group $1$, Period $6$.

Darmstadtium ($Ds$)

The specific element located at Group $10$, Period $7$.

Argon ($Ar$)

The specific element located at Group $18$, Period $3$.

Chemical Symbol Word Challenge

An activity where chemical symbols from the Periodic Table are used to create words or phrases, such as using Barium ($Ba$), Cobalt ($Co$), and Nitrogen ($N$) to spell "BaCoN".
