What of the following elements would have properties most similar to cesium Cs?
To find elements that are chemically similar, you don't need to look further than the related elements in the same family (columns). The periodic table is formed so elements in the rows have similar chemical properties. Cesium is in the first family, the alkali metals. All metals in this family are similar and will react explosively with water. The reactivity increases as you go down the column, with francium being the most reactive. But since francium is radioactive, I would say rubidium is most similar to cesium.
Why are rubidium and cesium kept in a sealed glass tube?
Because they are extremely reactive to any moisture in the air.See the Related Questions about the reactivity of the alkali metals (rubidium and cesium are the most reactive of the alkali metals).
What is the atomic weight of rubidium?
The atomic weight of rubidium is approximately 85.47 grams per mole.
How are elements compound matter and substance related?
Elements are the building blocks of all matter, and they cannot be broken down into simpler forms by chemical reactions. Compounds are formed when elements combine chemically in specific ratios to create new substances with distinct properties. Substances can refer to elements or compounds, as they both represent forms of matter with specific physical and chemical characteristics.
What is a family or group of elements?
A family or group of elements in chemistry refers to a set of elements classified together based on their similar properties and chemical behaviors. Elements in the same group often share common characteristics such as valence electron configuration and reactivity patterns. Examples include the alkali metals group (Group 1) and the halogens group (Group 17) on the periodic table.

What are the alkali metals?
They are the elements in the first column of the periodic table: lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr).See the Related Questions to the left for more information about the alkali metals and their properties.
Which other elements contain the same number of outer electrons as potassium?
All the elements in the first column of the periodic table have 1 valence electron.They include: lithium (Li), sodium (Na), postassium (K), rubidium (Rb),cesium (Cs), and Francium (Fr).See the Related Questions for more information.

How are matter atoms and elements related?
They are related because atoms are made of matter,elements are made of atoms,and matter is made up of elements.
What is half-life of rubidium and how is it related to and used in conjunction with potassium?
The half-life isn't specified for an element, but for an isotope. Check the Wikipedia article titled "Isotopes of rubidium" for more details.Rubidium-87 occurs naturally; it has a half-life of 4.92×1010 years.
