100

The attraction between various combinations of atoms will produce these kinds of bonds which form molecules.

What are chemical bonds?
100

Ionic compounds always contain these 2 ions.

What are positive and negative ions?

100

These are made by combining 2 or more metallic elements.

What is an alloy?

100

The dots in a Lewis dot diagram represent these.

What are valence electrons?

100

This is the formula to find formal charge.

# of valence electrons - # of lone and shared electrons

200
This family of elements have the least tendency to form ionic bonds.

What are Noble Gases?

200

An ionic compound can be identified by this in its formula.

What is a metal or nonmetal?

200

They are good conductors of electricity, malleable, and ductile.

What are the properties of metallic bonds?

200

What is the shape of Br2?

Linear.

200

The atoms in a molecule can be assembled differently when drawing a Lewis diagram because of this.

What are formal charges?

300

The reaction of a metal and a nonmetal form this kind of bond.

What is an ionic bond?

300

Why are ionic compounds generally stable?

The attractions between cations and anions within ionic compounds are strong.

300
This type of bond is surrounded by a sea of delocalized electrons.
What are metallic bonds?
300

What is the shape of CH4?

Tetrahedral.

300

This is how you can tell which structure is more likely to form formal structures.

What is the formal charge closest to 0?

400
As this increases, the degree of ionic character increases.

What is electronegativity difference?

400
This formula reflects the smallest whole number ratio of ions.

What is the formula of an ionic compound?

400

This determines the amount of electrons delocalized in the sea of electrons.

What is the number of valence electrons.

400

What is the shape of CH2O?

Trigonal planer.

400

Any molecule that can have double or triple bonds located between different atoms.

What are resonance structures?

500

This bond is a chemical bond between atoms with smaller electronegativities in which valence electrons are shared.

What are covalent bonds?

500

If a ionic compound contains a metal with a charge that differs in other compounds, this is why the charge of the metal needs to be specified in the name of the compound.

What is the metal can form more than 1 kind of cation?

500

The attractions become greater when this happens.

What happens when the charge of the cations and number of electrons increase?

500

Only these types of bonds are allowed in Lewis dot diagrams.

What are covalent bonds?

500

You add an electron to the total number when this happens.

What do you do when there is a negative charge in from of an ion?
