Atomic Structure

100

Name the subatomic particle(s) that affect the mass of the atom.

protons and neutrons

200

How many electrons would a neutral sodium atom have?

11

300

Which period will have elements with 3 orbitals (shells)?

Period 3

400

What is the charge of an atom that has lost 3 electrons?

+3

Organizing the Periodic Table

100

Which side of the periodic table are metals found?

Left side

200

What are columns (up and down) of the periodic table called?

Groups

300

******* DAILY DOUBLE ************

Which letter does not appear anywhere on the periodic table?

J

400

Which group(s) contain the most reactive elements?

Group I and group VII

500

Which part of the periodic table (top/bottom, right/left) will have the largest atoms (biggest radius)? (bonus if you can tell us why!)

The bottom left corner (francium).

Because there are less protons "pulling" the outer electrons closer to the nucleus. There are more protons in elements on the right side, so they can 'keep' the electrons closer which decreases the radius of the atom.

Ions and Ionic Bonds

100

What is the charge of a cation?

Positive

200

********DAILY DOUBLE *********

What was Dmitri Mendeleev's favorite fish?

Anion

400

How many chlorine atoms bond with calcium to form calcium chloride?

2

500

Why do the atoms in an ionic bond stick together?

Because they have opposite charges.

Isotopes
