Aluminium would have similar properties to which of the following chemical elements? Germanium
Gallium
Iron
Copper

Gallium

Explanation:

Elements found in the same group of the periodic table, possess similar chemical properties. Aluminium and Gallium are found in Group 13 of the periodic table,hence, have similar properties.

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.
