• Number of neutrons

• Melting point

Element Y is located in Group VII of the Periodic Table. Write the formula of the ion formed by element Y.

• Y⁻

• Y²⁺

• Y³⁻

• Y⁺

Give two physical properties of element Y.

• Any two of the following: Brittle, Poor conductor of heat, Poor conductor of electricity, Low melting/boiling points, Dull

• Shiny, Malleable, Good conductor of heat, High melting/boiling points

• Magnetic, Radioactive, Liquid at room temperature

• Highly reactive with water, Forms colorful compounds, Soft and easily cut

Reactivity decreases going down Group VII because:

• the outer electrons are further from the nucleus and are less easily gained

• the atoms get smaller and attract electrons more strongly

• the number of protons decreases down the group

• the outer shell becomes more stable down the group

Going down the group, the number of electron shells .................. so the outer electron is .................. the nucleus.

• increases, further from

• decreases, closer to

• remains the same, at the same distance from

• increases, closer to

There are .................. electrostatic forces of attraction between the outer electron and nucleus making it harder for the element to .................. an electron.

• weaker, gain

• stronger, lose

• stronger, gain

• weaker, lose
