Understanding the Periodic Table

Who was responsible for creating the periodic table?

• Albert Einstein

• Dmitri Mendeleev

• Isaac Newton

• Marie Curie

How are elements arranged in the periodic table?

• By increasing atomic mass

• By alphabetical order

• By increasing atomic number

• By date of discovery

What is a key characteristic of elements within the same group?

• They are all metals

• They have the same number of electrons in their outer shell

• They have the same number of protons

• They have the same atomic mass

What is the reactivity trend for group 1 elements as you move down the group?

• Reactivity fluctuates

• Reactivity remains the same

• Reactivity increases

• Reactivity decreases

Which group is known as the halogens?

• Group 7

• Group 1

• Group 2

• Group 0

Which group of elements is known for having full outer electron shells?

• Transition metals

• Noble gases

• Halogens

• Alkali metals

Why are noble gases considered unreactive?

• They have the same number of protons and neutrons

• They have no electrons

• They have full outer shells

• They have incomplete outer shells

What separates metals from nonmetals in the periodic table?

• A vertical line

• A dotted line

• A zig-zag line

• A horizontal line

What is unique about the transition metals?

• They are all gases

• They have variable oxidation states

• They are all nonmetals

• They are all radioactive

What should you remember about different periodic table presentations?

• They are outdated

• They present the same information in different ways

• They all have different information

• They are only for advanced chemists
