Periodic Table

100

What is the periodic table organized by?

What is Atomic number

200

What is a column and a row in the periodic table called?

What is a group and period

300

What does a period represent?

What is the highest energy level an electron can occupy

400

What is the element in group 8 and row 5?

What is Ru

500

Name a element that is part of the lanthanides 

What is La, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, or Lu

Periodic Trends

100

What is the trend for Atomic radius?

What is bigger right to left and top to bottom

200

What is the trend for electronegtivity?

What is higher left to right, down to up, and noble gases have none

300

What is the trend for metallic elements?

What is more metallic up to down, right to left

400

Explain the trend for Atomic radius

What is the protons have a stronger pull so it pulls the electrons closer to the nucleus making it smaller, and adding an energy level greatly increases the size.

500

What is the trend for first ionization energy and explain why.

What is higher to the right and up. This is because the smaller the atom is, the harder it is to take off a valence electron since it would be closer to the nucleus.
