a scientist is trying to determine the identity of an element. it highly reactive in water and forms an ionic bond with chlorine. its very shinny. the element is likely?
A) from Group 17
B) from group 1
C) from group 15
D) a noble gas
Cant anyone just give a simple answer
What is the answer to this?
To determine the identity of the element, we need to analyze the given information.
First, we know that the element is highly reactive in water. Group 17 elements, known as halogens, are highly reactive in water. They include fluorine, chlorine, bromine, iodine, and astatine.
Second, we are informed that the element forms an ionic bond with chlorine. Chlorine is a halogen from Group 17, and since the element forms an ionic bond with chlorine, it suggests that the element is a metal.
Lastly, the element is described as being very shiny. Group 1 elements, also known as alkali metals, are typically very shiny in their pure forms. Alkali metals include lithium, sodium, potassium, rubidium, cesium, and francium.
Based on the given information, the element is highly reactive in water, forms an ionic bond with chlorine, and is very shiny. Taking all of this into consideration, it is most likely that the element belongs to Group 1, which makes the correct answer:
B) from group 1
Well, it is certainly not from over on the right there where the Halogens live.
Since Cl is a halogen, group 7 which is missing an electron in the outer shell and wants to grab one to become a Cl-1 ion,
we really want something with an extra electron easily removed. That means way over on the left, like lithium or Sodium or Potassium. Those are the group 1 column. If it is shiny it might be Lithium
