Periodic Table

Which table below correctly lists the properties of metals and nonmetals?

• A

• B

• C

• D

Answer explanation

Choice D accurately lists the properties of metals and nonmetals, highlighting key differences such as conductivity, malleability, and reactivity, making it the correct answer.

Where are the non-metallic elements found in the periodic table?

• In the middle

• In the top rows

• On the left-hand side

• On the right-hand side

Answer explanation

Non-metallic elements are primarily located on the right-hand side of the periodic table. This area includes elements like oxygen, nitrogen, and carbon, which are essential for life and exhibit non-metallic properties.

How would this element be classified?

• Metal

• Nonmetal

• Metalloid

• Metamorphic

Answer explanation

The element is classified as a metal because metals are typically shiny, good conductors of heat and electricity, and malleable. Nonmetals and metalloids have different properties, while metamorphic refers to a rock type, not an element.

Match the type of elements

• lose or share electrons

• Non-metals

• share electrons

• metalloids

• lose electrons

• metals

• share or gain electrons

• Hydrogen

Elements were organized to make a periodic table in the following order

• properties

• atomic number

• atomic mass

Match the following number of valence electrons with their group

• 8

• 8A (18)

• 2

• 1A

• can vary

• 3-12 Group B

• 7

• 7A (17)

• 1

• 2A

How many periods are on the periodic table?

• 5

• 6

• 7

• 8

Which elements have the most similar chemical properties?

• K and Na

• K and Ca

• K and Cl

• K and S

Match the following elements to the group they belong to.

• alkaline earth metal

• sodium

• noble gas

• argon

• halogen

• calcium

• alkali metal

• chlorine

Anytime you see the word SEMICONDUCTOR - what substance do you have?

• Metal

• Nonmetal

• Metalloid

Answer explanation

Semiconductors are materials that have properties between metals and nonmetals. They are typically classified as metalloids, which can conduct electricity under certain conditions, making 'Metalloid' the correct choice.
