Family of elements that includes helium and neon is the Noble Gases family. These elements are also known as Group 18 elements on the periodic table. The Noble Gases family consists of elements that are typically inert or non-reactive due to their full outer electron shells. This stability makes them unique compared to other elements.
1. **Helium (He)** is the second lightest and second most abundant element in the observable universe. It is colorless, odorless, tasteless, and non-toxic. Helium is often used in balloons, airships, and as a cooling medium in cryogenics.
2. **Neon (Ne)** is a noble gas that gives off a distinct reddish-orange glow in a vacuum discharge tube. It is commonly used in neon lights, advertising signs, and television tubes.
In summary, helium and neon belong to the Noble Gases family, which are characterized by their stable and unreactive nature due to having a full outer electron shell.
