Intro to the Periodic Table

What is the Octet Rule?

• Atoms will aim to have 8 neutrons

• Atoms want to have 3 electrons in their inner shell

• Atoms will gain or lose electrons to have 8 in their outer shell

• Atoms of oxygen will stay the same

Elements in the same group have the same...

• number of valence electrons

• atomic number

• number of energy level

• wavelength

Periods are...

• horizontal rows with the same number of valence electrons

• horizontal rows with the same number of energy level

• vertical columns with the same energy level

• horizontal rows with the same number of valence electrons

What does the number of valence dictate?

• The rarity of an element

• An element's atomic number

• How big an element is

• The chemical properties of an element

Metals are

• shiny

• slippery

• good conductors

• malleable and ductile

• mostly solids

What are the different types of elements on the periodic table?

• metals, metalloids, non-metals

• metals, noble gases, metals

• non-metals, gases, halogens

• alkali, non-metals, gases

What are the different groups on the periodic table

• helium, alkali metals, water metals, earth metals, gases, active gases, dormant gases

• halogens, hydrogen, alkali metals, transition metals, gases, metals, helium

• alkali metals, hydrogen, alkaline earth metals, transition metals, halogens, noble gases, actinides, lanthanides

• nitrogen, hydrogen, helium, neon, oxygen, transition metals, alkali metals, earth metals, halogens, actinides

What do groups in he periodic table have in common?

• number of neutrons

• properties

• reactivity

• atomic mass

Non metals are

• good conductors

• gases, liquids, or solids

• dull

• poor conductors

• brittle

Metalloids have properties that are

• chemical

• a combination of non metals and metals

• similar to hydrogen

• out of the ordinary
