Atoms
Elements
Molecules & Compounds
Extended Structures
100

The smallest unit of matter.

What is an atom?

100

The number at the bottom of a periodic table square.

What is the atomic mass?

100

When two or more atoms bond together.

What is a molecule?

100
A repeating arrangement of atoms or molecules that extends throughout the entire structure.

What is an extended structure?

200

This particle makes up the atoms nucleus and has a positive charge.

What is a proton?

200

These determine what an elements atomic number is.

What are protons?

200

The attractive force that holds atoms together.

What is a bond?

200

The form extended structures usually take. 

What are crystals?

300

This particle orbits the atoms nucleus and has a negative charge.

What is an electron?

300

Atomic Mass - Atomic Number =

What is the formula for finding neutrons?

300

This occurs when atoms share electrons. Can come in the form of single, double, or triple. 

What is a Covalent Bond?

300

True or False: Extended Structures can only be formed by two distinct elements bonding together.

False: Extended Structures can be formed from atoms of the same element, as well as two different elements.

400

This particle also makes up the atoms nucleus but has no charge.

What is a neutron?

400

Elements that share similar properties and all belong to the same column.  

What is a group?

400

This occurs when atoms steal electrons from each other.

What is an ionic bond?

400

Whereas simple molecules end, extended structures can continue to form indefinitely. 

What is the main difference between simple molecules and extended structures?

500

This is what we call atoms when they have an electric charge.

What is an ion?

500

The horizontal rows on the periodic table. 

What is a period?

500

This forms when two atoms from different elements bond together.

What is a compound and molecule?

500

The defining feature of extended structures.

What is repeating patterns?
