100

This element is the most common in the universe and has one valence electron.

Hydrogen

100

Elements of this family were among the last discovered because they are inert, having a full valence shell.

Noble gases

100

A positively charged ion

Cation

100

This bond forms typically forms between metals and non-metals.

Ionic bond

100

As a general trend, atomic radius increases toward this corner of the periodic table.

Lower left

200

Found in toothpaste, this element is the most reactive of all elements and has 7 valence electrons.

Flourine

200

Elements of this family are used to harden teeth, sanitize drinking and swimming water and have 7 valence electrons.

Halogens

200

A negatively charged ion

Anion

200

Electrons are shared between atoms like a basketball being shared by two players in a game of P I G.

Covalent bond

200

The reactivity of metals increases toward this corner of the periodic table.

Lower left

300

Named after coal, this element has 4 valence electrons and forms millions of compounds that are key to living organisms.

Carbon

300

Elements of this family are the most reactive metals, and form ions with a 1+ charge.

Alkali Metals

300

Metals in Group 2 will form ions having a charge of...

2+

300

The strongest type of bond and is the result of two different types of ions being attracted to each other.

Ionic bond

300

With the exception of the noble gases, the reactivity of non-metals increases toward this corner.

Upper right

400

This element has 5 valence electrons and makes up about 78% of the atmosphere.

Nitrogen

400

Elements of this family are in more than one group, are NOT shiny, and do NOT conduct electricity.

Other non-metals

400

Oxygen, having six valence electrons, will form an oxide ion having a charge of...

2-

400

The valence electrons are delocalized, forming a sea of electrons moving around many positively-charged atoms.

Metallic bond

400

Mendeleev was not the first to make a type of periodic table, but he was the first to...

make predictions from it.

500

This element has 1 valence electron, floats in water, and is used in medicine to treat mental illness.

Lithium

500

Some elements of this family can form up to 4 different cations because of the different kind of electron configuration they have. They are shiny and good conductors of heat and electricity.

Transition Metals

500

If oxygen (group 16) and sodium (group 1) bond, there will be ______ sodium atoms per 1 oxygen atom.

2

500

Valence electrons are shared, but not equally, creating a positive pole and a negative pole in the compound.

Polar covalent bond
