A scientist is trying to determine the identity of an element. It is highly reactive in water and forms an ionic bond with chlorine. It is also very shiny. The element is most likely
A)from group 17
B)from group 1
C)from group 15
D)a noble gas
Mrs. Sue Is it C?
Definitely it isn't a noble gas since noble gas are stable and unreactive. They can still form compounds with other elements though.
Group 15 is also group 5A (Nitrogen, Phosphorus, etc.), and Group 17 is also group 7A (Fluorine, chlorine, etc.). Elements in these groups do not usually form ionic bonds; they are more on forming covalent bonds since they're non-metals.
Thus, that leaves us with B. from Group 1 (Hydrogen, Lithium, etc.). They are metals (except Hydrogen) which react violently with water, and they form ionic bonds, for they lose outer electrons easily.
Hope this helps~ `u`

To determine the identity of the element described, we need to consider its properties and compare them to the properties of elements in the periodic table.
First, the element described is highly reactive in water. This suggests that it is a metal since metals are known for their reactivity with water.
Next, the element forms an ionic bond with chlorine. This further supports the idea that it is a metal since metals tend to lose electrons to form positively charged ions in ionic bonds.
Lastly, the element is described as very shiny. This characteristic is known as metallic luster, which is a property commonly associated with metals.
Now, let's examine the answer choices:
A) Group 17 elements in the periodic table are known as the halogens, which include chlorine. However, halogens are nonmetals and not known for being highly reactive in water or having metallic luster.
B) Group 1 elements, also known as alkali metals, are highly reactive with water, and they do have metallic luster. This makes them a possible choice.
C) Group 15 elements in the periodic table are known as the pnictogens, which include nitrogen. These elements are typically nonmetals and do not generally have metallic luster or react strongly with water.
D) Noble gases are known for being unreactive and do not typically form bonds with other elements. They do not exhibit metallic luster.
Based on the given information, the element described is most likely from Group 1 (B) – the alkali metals.
