100

The three main subatomic particles of an atom.

What are protons, neutrons, and electrons?

100

As you look from left to right on the periodic table, this trend increases.

What is Ionization Energy?

100

An ion has done this with one or more electrons.

What is gained or lost?

100

Electron configuration can be described as an element's ___________. 

What is address?

100

The location of valence electrons

What is the outermost shell?

200

These particles make up the nucleus of an atom.

What are protons and neutrons. 

200

As you look from left to right on the periodic table, this trend increases.

Electronegativity

200

An ion with a positive charge. Some might say a "paws"itive charge.

What is a cation?

200

1s2s2p6  (Name the Element)

What is Neon?

200

The number of electrons the first energy level/shell/ring can hold. 

What is two?

300

Each of the subatomic particles and their charges.

What are positive protons, neutral neutrons, and negative electrons?

300

As you look from top to bottom on the periodic table, this trend increases.

Atomic Radius

300

An ion with a negative charge. 

What is an anion?

300

Describe Hund's Rule of electron orbitals. 

Electrons want to go in their own orbital first, before they pair up with another.

300

How do energy levels relate to the periodic table?

Add an energy level as you move down the group/column.

400

This determines the chemical properties of an element.

What is the number of valence electrons?

400

The tendency of an atom to attract an electron it itself.

What is electronegativity?

400

1. The chemical symbol

2. How many electrons gained or lost.

3. The charge

What is ion notation?

400
  1. 1s orbital: 2 electrons (↑↓)
  2. 2s orbital: 2 electrons (↑↓)
  3. 2p orbitals: 6 electrons (↑↓ in each of the three orbitals)
    • 2p: (↑↓) (↑↓) (↑)
  4. 3s orbital: 2 electrons (↑↓)
  5. 3p orbitals: 1 electron (↑) in one of the three orbitals.

What is the orbital diagram for Aluminum?

400

When electrons move from low energy levels to high energy levels...they "crash" and emit photons of light, they are moving between this state and this state.

What is ground state and excited state. 

500

Identified as the number of protons in an element

What is atomic number?

500

The reason why atomic radius increases as you move down the group.

What are increasing number of electron shells/energy levels?

500

A common cation or anion.

What is flouride? 

500

Electron configuration tells us this about an element

What are chemical properties?

500

How do energy levels relate to the periodic table? Think about periodic trends!

As you move across a period (from left to right), electrons are added to the same energy level, resulting in changes in atomic properties
