What properties does rubidium have?
The key properties of rubidium are:
- It is the second most electropositive metal.
- It is soft and silvery.
- It is highly inflammable.
- It is mildly radioactive.
- It ignites spontaneously in air.
- It vigorously reacts with water and combines with the halogens.
What ion is rubidium most likely to form?
1+
Rubidium is in group 1, so it is likely to form an ion with a 1+ charge. Nitrogen is in group 15, so it is likely to form an ion with a 3- charge.
Is rubidium an ionic compound?
Rubidium(1+) is a monovalent inorganic cation, a monoatomic monocation, an alkali metal cation and a rubidium molecular entity….4.3Related Element.

Is rubidium a metal or nonmetal?
alkali metal
rubidium (Rb), chemical element of Group 1 (Ia) in the periodic table, the alkali metal group. Rubidium is the second most reactive metal and is very soft, with a silvery-white lustre.
Is rubidium an alkali metal?
Group 1A (or IA) of the periodic table are the alkali metals: hydrogen (H), lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr).
Is rubidium an anion or cation?
Rubidium(1+) is a monovalent inorganic cation, a monoatomic monocation, an alkali metal cation and a rubidium molecular entity.
Is rubidium a compound?
Rubidium is a chemical element with symbol Rb and atomic number 37.
What type of element is rubidium?
alkali metals
Rubidium is one of the alkaline metals, as group one of the periodic table are otherwise known. The alkali metals have a single electron in their outer shell, which makes them highly reactive with oxygen, water and halogens, and also means that their oxidation state never exceeds +1.
Which statement about rubidium is not correct?
Rubidium is a Group I metal. Which statement about rubidium is not correct? It has one electron in its outer shell. It reacts vigorously with water.
Is the charge of rubidium positive or negative?
Does rubidium have a positive or negative charge? Explanation: Rb atom has 37 electrons and 37 protons. when 1 electron is removed number of protons remains 37 but number of electrons is 36.36 negative charges is balanced by 36 positive charges. one extra proton is present so 1 positive charge.
What kind of metal is rubidium 1 +?
Rubidium (1+) is a monovalent inorganic cation, a monoatomic monocation, an alkali metal cation and a rubidium molecular entity. 5.3Related Element.
Is the charge of a Rb atom positive or negative?
Explanation: Rb atom has 37 electrons and 37 protons. when 1 electron is removed number of protons remains 37 but number of electrons is 36.36 negative charges is balanced by 36 positive charges. one extra proton is present so 1 positive charge. Likewise, what would be the charge of a rubidium ion?
What happens when rubidium is dissolved in water?
Rubidium, like sodium and potassium, almost always has +1 oxidation state when dissolved in water, even in biological contexts. The human body tends to treat Rb+ ions as if they were potassium ions, and therefore concentrates rubidium in the body’s intracellular fluid (i.e., inside cells).
