Left

200

Nonmetals are located to the ___________ of the staircase.

Right

300

_______________ are located on the staircase, and separates the metals from the non-metals.

Metalloids

400

I am ductile, solid, malleable, and a good conductor of heat and electricity.... What am I?

Metal

500

I share BOTH properties of metals and non-metals.  What am I?

Metalloid

Regions

100

How may Regions can be found on the Periodic Table?

6

200

This region is "pulled" from the middle of the Periodic Table, includes the Actinide and Lanthanide Series

Inner Transition Medals

300

I have ALL metallic properties, and am commonly referred to as the "heavy metals" due to my high density values... What Region am I?

Transition Metals

400

I am the most reactive and typically poisonous.  I can also exist in all three states of matter.  What Region am I?

Halogens

500

I can be found in the earth's crust and known for my variety of colors.  What Region am I?

Trends

100

How many Periodic Trends have we explored this semester?

5

200

Which element has a LARGER atomic radius?

Magnesium or Barium

Barium

300

Ionization Energy will INCREASE or DECREASE as we move left-to-right across the Periodic Table?

Increase

400

This is the ability of an atom to attract an electron.  It increases as we move left-to-right across the table.

Electronegativity

500

Why do atoms tend to get LARGER as we move down a group within the Periodic Table?

This is due to increased # of electrons and therefore more energy levels.

Atomic Structure

100

What is located in the center of an atom?

Nucleus - which holds the protons and neutrons 

200

What is the overall charge of the center of an atom?

Positive - due to the protons being present

300

What element am I?

I have 14 protons, 14 electrons, and 14 neutrons

Silicon

400

Who discovered the electron?

JJ Thomson

500

How many total electrons will you need to fill the 2nd energy level of an atom?

10 (2 in the 1st energy level; and 8 in the 2nd energy level)
