| Hint | Answer | % Correct |
|---|---|---|
| Colorless, odorless and almost completely nonreactive gases | Noble Gases | 79%
|
| Mostly dense, hard, and brittle metals that conduct heat and electricity well and have high melting points | Transition metals | 57%
|
| Very reactive, low melting points, excellent conductors of heat and electricity | Alkali metals | 50%
|
| More brittle metals with a poorer mechanical strength compared to transition metals | Post-transition metals | 50%
|
| Quite reactive and tend to bond with alkali metals | Halogens | 29%
|
| Poor conductors, brittle and non-malleable, typically gain electrons | Nonmetals | 29%
|
| Few occur naturally and all are radioactive | Actinides | 21%
|
| React readily, form numerous compounds, not found free in nature | Alkaline earth metals | 21%
|
| Intermediate conductivity, used in semiconductor technologies in electronic devices | Metalloids | 14%
|
| Shiny, silvery metals, typically ductile and malleable | Lanthanides | 0%
