GCSE 1.6 Periodic Table

Name the Russian scientist credited with creating 'The Periodic Table'.

• Marie Curie

• Dmitri Mendeleev

• Albert Einstein

• Niels Bohr

How are the elements ordered in The Modern Periodic Table?

• By increasing atomic number

• By increasing atomic mass

• By alphabetical order

• By date of discovery

What does the atomic number of an element tell us?

• The number of electrons in the outer shell

• The number of neutrons in the nucleus

• The number of protons in the nucleus

• The number of isotopes of the element

What word is used to describe the columns in the Modern Periodic Table?

• Groups

• Periods

• Rows

• Blocks

Can you describe a trend in electronic structure that occurs as you cross a period (row) e.g. from Li to Ne?

• The number of neutrons remains the same

• The number of protons decreases

• The atomic mass decreases

• The number of electrons increases to fill the outer shell

What does the term 'Isotope' mean?

• Atoms of the same element with different numbers of neutrons

• Atoms of different elements with the same number of protons

• Atoms of the same element with different numbers of protons

• Atoms of different elements with the same number of neutrons

What are the two main groupings of elements within The Periodic Table?

• Metals and Non-metals

• Solids and Liquids

• Gases and Liquids

• Alkali metals and Halogens

Can you explain the link between an element’s electronic configuration and its position within The Periodic Table?

• Elements in the same period have the same number of protons

• Elements in the same group have the same number of electrons in the valence shell

• Elements in the same group have the same atomic mass

• Elements in the same period have the same number of neutrons

Give the name of the most unreactive group of elements in The Periodic Table and explain why they are unreactive.

• Noble gases; they have a full outer electron shell

• Alkali metals; they have one electron in their outer shell

• Halogens; they need one electron to complete their outer shell

• Transition metals; they have partially filled d-orbitals

Use your Periodic Table to select the MOST reactive metal. Give a reason for your selection.

• Sodium; it is highly reactive with water

• Lithium; it has the smallest atomic radius

• Francium; it has the largest atomic radius

• Magnesium; it is a strong reducing agent
