Which element in the list is the most reactive? (1 point) Responses S S Cs Cs Ba Ba C
The most reactive element in the list is Cs (Cesium).
To determine which element in the list is the most reactive, we can look at their positions on the periodic table. Reactivity generally increases as you move down a group and from right to left across a period on the periodic table.
In the given list: S, S, Cs, Cs, Ba, Ba, C
Sulfur (S) is in the 3rd position, Cesium (Cs) is in the 5th position, and Barium (Ba) is in the 7th position.
Comparing within the list, we can see that Cs and Ba are repeated twice, suggesting that they are present in higher quantities than S. Considering the periodic trends, Cs and Ba are both in the same group as S, which is Group 16. However, Cs is located below Ba on the periodic table, indicating that it is more reactive than Ba.
Therefore, the most reactive element in the list is Cesium (Cs).
To determine which element in the list is the most reactive, you need to understand the periodic table and the periodic trends. The reactivity of an element depends on factors such as its electron configuration and atomic radius.
One of the main periodic trends that affects reactivity is electronegativity. Electronegativity is the tendency of an atom to attract electrons towards itself in a chemical bond. Generally, the higher the electronegativity value, the more reactive the element.
In the given list, we have the following elements:
Sulfur (S): Electronegativity value = 2.58
Cesium (Cs): Electronegativity value = 0.79
Barium (Ba): Electronegativity value = 0.89
Carbon (C): Electronegativity value = 2.55
Comparing the electronegativity values, we can see that sulfur (S) has the highest value of 2.58. Hence, sulfur is the most reactive element in the list given.
To find the electronegativity values, you can refer to a periodic table or use online resources that provide information on the electronegativity values of elements.
