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 element?

Explanation:

Question 1

Elements in the same group (vertical column) of the periodic table have similar chemical properties. 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.

In general, for non - metals (like those in groups 5A - 7A), reactivity increases as you move up a group. For example, fluorine (F) is more reactive than chlorine (Cl). Also, elements in the same group have similar reactivity trends.

Answer:

Aluminum (Al). Because elements in the same group (group 3A) have similar chemical properties.
