Question

Neon and argon are both in Group 18 of the periodic table. Which property do they most likely share?(1 point) Responses silver color silver color strong odor strong odor metallic texture metallic texture low or no reactivity low or no reactivity

Answer 1

Neon and argon are both noble gases found in Group 18 of the periodic table. The property they most likely share is **low or no reactivity**. This is due to their full valence electron shells, which make them stable and unlikely to form chemical bonds with other elements.

Answer 2

Which two elements most likely have similar properties? (1 point) Responses Cs and Rn Cs and Rn Li and Fr Li and Fr Ca and Sc Ca and Sc F and Ne

Answer 3

The two elements that most likely have similar properties are **Li and Fr**. Both lithium (Li) and francium (Fr) are alkali metals located in Group 1 of the periodic table, which means they share similar chemical properties, such as reactivity and the ability to easily lose one electron.

Answer 4

A scientist studies an element that has seven electrons in its outer shell, is fairly toxic, is a gas at room temperature, and is highly reactive. To which group of the periodic table does this element belong?(1 point) Responses 1 - alkali metals 1 - alkali metals 2 - alkaline earth metals 2 - alkaline earth metals 17 - halogens 17 - halogens 18 - noble gases

Answer 5

The element described has seven electrons in its outer shell, is fairly toxic, is a gas at room temperature, and is highly reactive. This matches the characteristics of elements in **Group 17 - halogens**. Halogens typically have seven valence electrons and are known for their reactivity.
