Question

use the following image for questions 1 and 2. 1. which element will most likely react in a similar way as boron? explain your answer. 2. how could you use this section of the periodic table to determine the reactivity of an el

Explanation:

Elements in the same group of the periodic table have similar chemical - reactivity because they have the same number of valence electrons. Boron (B) is in group 3A. Aluminum (Al) is also in group 3A. So, aluminum will most likely react in a similar way as boron due to their similar outer - electron configurations.

Answer:

Aluminum. The reason is that elements in the same group of the periodic table have similar chemical properties, and boron and aluminum are in the same group (3A).
