Question

Why do these elements have similar chemical properties?
1. H
2. Li
3. Na
4. K
5. Rb
6. Cs
7. Rr

Answer 1

These elements have similar chemical properties because they are all alkali metals in the first column of the periodic table. Alkali metals have similar characteristics such as being soft, highly reactive, and having low melting points. They also have one electron in their outermost shell, which makes them highly reactive and likely to form ionic compounds by losing this electron. These similarities in electron configuration and reactivity contribute to their similar chemical properties.

However, the element "Rr" is not a known element in the periodic table, so its chemical properties cannot be compared to the other alkali metals.
