Atomic structure and bonding

It's in style: Periodic Trends

100

Which element has a larger atomic radius Carbon or Oxygen?

Carbon

200

This term, which shares its name with a popular pasta shape, increases by one after every period

Shell

300

Families on the periodic table share this trait

Valence electrons

400

Step between these three elements in the third period and you'll transition from a metal, to a metalloid, to a nonmetal   

Aluminum, Silicon, and Phosphorus 

500

Mendeleev was able to predict missing elements in his early version of the periodic table due to proton numbers doing this 

Increasing

The element of surprise

100

67: When adding these notorious numbers together it equals the atomic number of this useful metal

Aluminum

200

Earth is home to this type of lifeform 

Carbon

300

It might feeling boring but this second period metal is on top of the world

Boron

400

I’m not lion about Dorothy's heartless friend being made of this element

Tin

500

You might mistake this reactive dietary mineral for an affirmative

Potassium-K  

Dance of the Valence

100

This noble family refuses to give or take their electrons 

The noble gases, 18th group 

200

I wouldn’t throw sodium into a lake due to this electron configuration

one valence 

300

Seven is the lucky number for this group of elements

Halogens

400

Got milk? Calcium is part of a family who have this many valence electrons

Second/Two

500

It’s not peanut butter jelly time in this family who share what number of electrons

4

Bonding over science...

100

This lonely element commonly creates covalent bonds

Hydrogen

200

Is the following molecule Ionic or covalent: NaCl

Ionic

300

Is the following molecule Ionic or covalent: C2

Covalent

400

Is the following molecule Ionic or covalent: CH4

Covalent

500

Is the following molecule Ionic or covalent: BaS 

Ionic

...One atom at a time

100

I’m positive that these particles live in the nucleus of an atom

Protons

200

I don’t have strong feelings about this particle that when added to protons makes up the majority of the mass of an atom

Neutrons

300

Don’t be so down on this subatomic particle that orbits the nucleus of an atom.

electron

400

This is the term for when two atoms form a bond to make a chemical substance

A molecule

500

I spy with my little eye these one or two letters, such as C or He, that represent the name of an element
