The __ elements are in the upper left of the periodic table, while the __ elements are found in the lower right.

• Heaviest, Lightest

• Gas, Solid

• Lightest, Heaviest

• Nonmetal, Metal

The vertical (up and down) columns in the Periodic Table are called:

• Groups

• Periods

• Compounds

• Elements

Sodium (Na) is found in which period?

• 1

• 2

• 3

• 4

The atomic number tells you what?

• The number of electrons

• the number of neutrons

• The number of protons

• The group number

Based on their position on the periodic table, which list correctly orders the elements from heaviest to lightest?

• Sn, Fe, K, P, Na

• Na, P, K, Fe, Sn

• Na, K, Fe, Sn, P

• P, Sn, Fe, K, Na

When a nonmetal is hit with a hammer it will crumble or break (Brittle). Metals on the other hand will bend when it is hit. What physical property is indicated?

Hint: Opposite of brittle

• conductivity

• brittle

• malleability

• ductility

What are electrons on the outer most shell called?

• Valence Electrons

• Neutron

• Electron

• Proton

When are atoms the least reactive?

• when their outer most shell is full

• when their shell is looking for one more electron

• when their shell is trying to lose one last electron

• atoms are not reactive ever

Chemical bonds are formed due to an atoms...

• reactivity

• ability to lose protons

• ability to gain protons

• ability to lose neutrons

How can you tell how many protons an element on the periodic table has?

• By looking at the atomic number (A=P=E)

• You can not

• By the chemical symbol

• the atomic mass
