What group is Na K and RB in?
What group or period number is Na K and Rb in? Sodium, potassium and rubidium are in the first group of the periodic table. Sodium is in the period 3. Potassium is in the period 4. Rubidium is in the period 5. What atomic radius is larger Rb or Sr?
How many electrons does rubidium (Rb) have?
Here is the table showing the capacity of orbits to hold electrons. Number of electrons in shells. 1st shell can hold 2 electrons. 2nd shell can hold 8 electrons. 3rd shell can hold 18 electrons. 4th shell can hold 32 electrons. Now the atomic number of Rubidium (Rb) is 37. Hence, the rubidium element has the electrons arrangement 2, 8, 18, 8, 1.

What group is RB in on the periodic table?
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 RB a transition metal?
Answer and Explanation: Rubidium is an S-block element and belongs to an alkali metals family. It has 37 electrons and has only one oxidation state thus disqualifying it to be a transition metal.
Is RB a nonmetal or metal?
Rubidium is a chemical element with symbol Rb and atomic number 37. Classified as an alkali metal, Rubidium is a solid at room temperature.
Is rubidium located in the 5th period?
Rubidium is the first element placed in period 5. It is an alkali metal, the most reactive group in the periodic table, having properties and similarities with both other alkali metals and other period 5 elements.

What element is in period 5 Group 8?
Group 8 is a group (column) of chemical elements in the periodic table. It consists of iron (Fe), ruthenium (Ru), osmium (Os) and hassium (Hs).
Which is not a transition metal?
On the basis of this definition, scandium and zinc do not count as transition metals - even though they are members of the d block. . The zinc ion has completely filled d orbitals and also it does not meet the definition either. Therefore, zinc is not a transition element.
How do you know if something is a transition metal?
Explanation: The transition elements are located in groups 3-12 (IIIB-IIB), which are in the d-block. Group 3/IIIB contains the inner transition elements in periods 6 and 7. They are the lanthanides and the actinides and are in the f-block.
Are lanthanides and actinides transition metals?
The lanthanides and the actinides at the bottom of the table are sometimes known as the inner transition metals because they have atomic numbers that fall between the first and second elements in the last two rows of the transition metals.
What are transition metals 12?
Transition elements or transition metals are elements that have partially filled d orbitals. IUPAC defines transition elements as an element having a d subshell that is partially filled with electrons that are able to form stable cations even with an incomplete d orbital.
