The original periodic table was organized in order of increasing what?

Atomic Mass

100
The "Main Group Elements" consist of which groups?
1,2, 13-18
100

All elements in this category of elements are considered radioactive. 

Actinides 

100

A predictable change in a particular direction on the periodic table is called a: 

Periodic trend

100

True or False? Identical twins have identical finger prints.

False

200

How many elements were on the periodic table when Dimitri Mendeleev first created it?

63

200

The elements in this group are rarely found in nature in their pure form due to having the highest reactivity.

Group 1: Alkali Metals

200

This element does is in its own category due to having only one proton and one electron.

Hydrogen

200

The energy required to remove an electron from an element; _________ as you move down.

Ionization Energy; decreases

200

Most particles have to flow through a "medium" of some sort, except for light particles--which are called: 

Photons
300

Currently, the elements on the periodic table are organized in order of increasing what?

Atomic number

300
Elements in this group will typically bond with Alkali metals to form salts.

Group 17: Halogens

300

Considered a noble gas despite not having 8 valence electrons.

Helium

300
The "size of an atom"; __________ as you move down.

Atomic radius; increases

300

Mrs. Meusch's middle name

Nicole

400
The law of octaves states that physical and chemical properties of elements (when arranged in order of increasing atomic mass) seem to repeat every _________ elements.

eight

400

These elements are chemically inert due to having a stable electron configuration of 8 valence electrons.

Group 18: Noble Gases

400

The number of elements NOT considered to be metals: 

24

400

The ability of an atom to attract electrons; _______ as you move across.

Electronegativity; increases

400
What happens to your brain when you learn something new?

Changes shape (forms new paths; neuroplasticity) 

500

Elements within the same group have the same number of ___________.

Valence Electrons

500

These metals do not always follow all of the other rules of chemistry due to having only partially filled d-orbitals.

Transition Metals

500

Most common element in the entire universe

Hydrogen

500

The number of the "row" that elements are in indicates the number of ____________________ that atom has.

Energy Levels
