Question 3
A)How are reactivity and electronegativity related?(1 point)
Responses

An element will be more reactive if it has a very high or very low electronegativity.
An element will be more reactive if it has a very high or very low electronegativity.

Answer 1

Here are the answers to each question based on periodic table trends:

Question 1: A) Which element would have the lowest electronegativity?

• Answer: an element with a small number of valence electrons and a large atomic radius. (Elements with fewer valence electrons and larger atomic radii tend to lose electrons more easily and have lower electronegativity.)

Question 2: A) Which elements on the periodic table are the least reactive?

• Answer: the group with helium at the top. (Noble gases like helium are the least reactive due to their complete valence electron shells.)

Question 3: A) How are reactivity and electronegativity related?

• Answer: Elements with lower electronegativity are more reactive than elements with higher electronegativity. (Lower electronegativity means an element is more willing to lose electrons, making it more reactive.)

Question 4: A) Which element listed would have the greatest electronegativity?

• Answer: fluorine. (Fluorine is the most electronegative element in the periodic table.)

Question 5: A) Which elements would react most easily with each other?

• Answer: an element with a high electronegativity and an element with a single valence electron. (An element with a single valence electron is likely to lose that electron readily, while a highly electronegative element will attract electrons strongly, promoting reactivity between them.)
