Wavelength

The distance between two waves

New cards
2

Amplitude

The height of a wave

New cards
3

How often a wave goes up and down

New cards

The speed of light

c = 3.0 x 10^8 m/s

New cards

In order for an electron to move to another level they have to...

...absorb a specific amount of energy

New cards
10

Excited State

When electrons absorbs energy and moves to a higher energy level

New cards
11

Ground State

When electrons "fall" back to their original energy level, they release light

New cards
12

Are excited states stable or unstable?

Unstable

New cards
13

How does the Emission Spectra connect to changing the color of light?

The higher the fall the more energy is released, changing the color of light produced.

New cards
14

What are the 3 rules for Electron Configurations?

• Aufbau principle • Pauli Exclusion Principle • Hund’s Rule

New cards
15

Aufbau

Electrons occupy orbitals of lower energy first.

New cards
16

Pauli Exclusion Principle

An orbital can hold only two electrons and they must have opposite spin.

New cards
17

Hund's Rule

In a set of orbitals, the electrons will fill the orbitals in a way that would give the maximum number of parallel spins (maximum number of unpaired electrons).

New cards
18

In the configuration: 1s^2, what does 1 mean?

The MAIN energy level

New cards
19

In the configuration: 1s^2, what does "s" mean?

Sublevels

New cards
20

In the configuration: 1s^2, what does ^2 mean?

Number of electrons in the sublevel

How to calculate the noble gas abbreviation.

  1. Use the last noble gas that is located in the periodic table right before the element.

  2. Write the symbol of the noble gas in brackets.

  3. Write the remaining configuration after the brackets. Ex: Fluorine: [He] 2s^2 2p^5

New cards
26

A family is a ? on the periodic table

27

Where are the alkali metals?

First column

New cards
28

Where are the alkaline earth metals?

Second column

New cards
29

Where are the transition metals?

Middle section

New cards
30

Where are the metalloids?

Staircase

New cards
31

Where are the halogens?

Second to last column

New cards
32

Where are the noble gases?

Last column

New cards
33

Atomic radius

the size of the atom. PLURAL : Atomic radii

New cards
34

Atomic radius gets (smaller/larger) going down a group and why?

Larger, because we are adding another valence shell.

New cards
35

Atom raduis get (smaller/larger) across a period and why?

Smaller, because the charge in the nucleus is increasing.

New cards
36

Electronegativity

A measure of the attraction an atom has for electrons when bonded.

New cards
37

Electronegativity gets (smaller/larger) going down a group.

Smaller

New cards
38

Electronegativity gets (smaller/larger) going across.

Larger

New cards
39

Which element has the most electronegativity?

F (Fluorine) has the greatest electronegativity at 4.0

New cards
40

Ionization Energy

The energy required to remove an electron from a gaseous atom or ion.

New cards
41

Ionization Energy gets (smaller/larger) going across.

Larger

New cards
42

Ionization Energy gets (smaller/larger) going down.

Smaller

New cards
43

Electron Affinity

Energy released when an electron is added to the atom.

New cards
44

Electron shielding

Atoms with more energy levels can't hold onto their valence electrons as strongly. The pull from the nucleus is partially blocked by each layer of electrons.

New cards
45

(Easier/harder) to remove an electron with more shielding?

Easier

New cards
46

Cation

When atoms lose valence electrons, they become positively charged ions.

New cards
47

Cations are always (smaller/larger) than the original atom.

Smaller

New cards
48

Anions

Atoms that gain electrons become negatively charged ions. Atoms gain electrons in their outermost shell.

New cards
49

Anions are always (smaller/larger) than the original atom.

Larger

New cards
50

Most reactive NON-metal?

Fluorine - F

New cards
51

Most reactive METAL?

Francium - Fr
