Periodic Table Virtual Lab Questions

To which of the three main chemical classes does Mercury (Hg) belong to? Don't forget you can read the theory page, look at the periodic table wall, or look at the periodic table in the Media tab if you are in doubt.

• Metals

• Non-metals

• Metalloids

• It's not an element in the periodic table

What kind of experiment would help you categorize some of the elements?

• All of the options are correct

• Observe their shininess

• Measure their electrical conductivity

• Test their ductility

Based on their phase of matter and what you already learned, which of the elements is clearly not a metal?

• Neon

• Sodium

• Copper

• Calcium

Which of the elements you tested doesn't have a characteristic metallic appearance?

• Phosphorus

• Sodium

• Calcium

• Copper

What are the different colors caused by that we can see in the flame test?

• Electrons falling back into their original shell

• Electrons being excited

• Metal atoms reacting with oxygen in the air

• Metal ions reacting with chlorine

Based on what you know about their location in the periodic table, what do Cs (cesium) and Cl (chlorine) react to?

• CsCl

• Cs2Cl

• CsCl2

• Cs2Cl2

Chlorine is part of the element family Halogens, which are also known as salt formers. How many valence electrons does Sodium have when forming an ionic bond with Chlorine?

• 0

• 1

• 2

• 3

Which group of elements have a full octet of electrons?

• Noble gases

• Transition metals

• Halogens

• Alkali metals

Applying the trends of oxidation states in the periodic table, what is a likely oxidation state of Chlorine? A simple rule to remember is the oxidation state is for unmixed atoms the same as their charge. Click 'View Image' to look at the periodic table.

• 7

• -7

• +1

What do you think is the reason for an increasing atomic radius within one group?

• Increasing number of electron shells

• Increasing number of electrons

• Decreasing number of protons

• Decreasing number of neutrons
