What is RB plus H2o?
2Rb(s) + 2H2O(l) --> 2RbOH(aq) + H2(g)
How do you make a the subject of r equals ab divided by a plus b?
Are you asking to have that equation solved for 'a' ?r = ab / (a + b)Multiply each side by (a + b) . . . ra + rb = abSubtract 'ra' from each side. . . . rb = ab - raFactor the right side . . . . . . . . . rb = a (b - r)Divide each side by (b - r) . . . . . a = rb / (b - r)
Two metallic wires A and B are connected in parallel combinationWire A has length 'l' and radius 'r'Wire B has length '2l' and radius '2r'Commute the ratio of total resistance of parallel combination?
FOR WIRE A , RA = rho L/A = rho L/pie* r square -equation 1 RB = rho 2L/pie(2r)square = rho 2L/4 pie*r square =rho L/2 pie * r square -equation 2 RA/RB = rho L/pie * r square * 2 pie *r square/rho L RA/RB = 2 RA = 2RB , RB = RA/2 1/Rp = 1/RA + 1/RB =1/RA +1/RB 1/Rp = 3/RA Rp/RA = 1/3 Hence the ratio is 1:3
37 (Rb)?
Rubidium
What shipping company using RB after 9 digits then CN?
It might be China Post Registered Mail.
Which of the following has the smallest radius is K plus Rb Rb plus K?
K+
Which element is the largest K Rb Na Li?
Rb (rubidium) is the largest element among K (potassium), Rb (rubidium), Na (sodium), and Li (lithium). This is because as you move down a group in the periodic table, the atomic size increases due to the addition of more electron shells.
What element has the smallest first ionization energy of Li Na Rb and K?
Rb
What species has the smallest atomic radius between Kor Mg orRb or Ca?
The species with the smallest atomic radius among K, Mg, Rb, and Ca is Rb (Rubidium). This is because atomic radius tends to decrease across a period from left to right in the periodic table, and Rb is located towards the right side of this group of elements.
Which has the smallest radius K Rb K Rb?
Potassium's atomic radius is smaller than rubidium's because potassium has fewer energy levels of electrons.
What has the smallest radius for rb k k rb?
In the context of atomic physics, the smallest radius for an atomic orbital is typically found in the hydrogen atom, where the radius is defined by the Bohr model. For the ground state (n=1), the Bohr radius is approximately 0.529 angstroms. In multi-electron atoms, the effective nuclear charge and electron-electron interactions can influence the size of the orbitals, but for a hydrogen-like atom (one electron), the smallest radius occurs at n=1.
What period is the element rb in the periodic table?
Rb is the symbol for the element, rubidium.
What atomic radius is larger Rb or Sr?
The atomic radius of Sr (Strontium) is larger than that of Rb (Rubidium). This is because atomic radius generally increases down a group in the periodic table, and Sr is located below Rb in the same group.
What is the smallest to largest Li Li Rb Cs?
Smallest to largest is going down the group 1. I.e. Li is smallest<Rb<Cs
How many protons does the element RB have?
Each atom of Rubidium (Rb) has 37 protons.
Which of these elements is the smallest element sodium potassium rubidium or cesium?
Of the Group 1 elements stated (Na, K, Rb, Cs), Caesium is the largest as it is the furthest down the group, and Sodium is the smallest of those as it is furthest up the group.
Which element has the smallest first ionization energy Na K Rb Li?
The element with the smallest first ionization energy is Francium, as it is located in Group 1 of the periodic table and has the largest atomic size. Among the elements listed, lithium (Li) would have the smallest first ionization energy as it is closer to the upper right of the periodic table compared to sodium (Na), potassium (K), and rubidium (Rb).
