What is the element represented by the symbol Rb?

Last Answer : Ans.K + ,Rb+ and Cs+ are large cations and superoxide ion is larger than oxide and peroxide ions. Since due to higher lattice energies,a large cation stabilizes a large anion,therefore these metals form Superoxides.

The increasing order of reactivity among group 1 elements is Li<Na<K<Rb<Cs whereas among the group 17 elements, it is F>Cl>Br>I. Explain.

Description : The increasing order of reactivity among group 1 elements is Li

Last Answer : Ans. In group 1 elements (alkali metals) the reactivity of the metals is mainly due to the electron releasing tendency of their atoms, which is related to ionization enthalpy, Since ... electron gain enthalpy. Since both of them decrease down the group, the reactivity therefore decreases.

The given figure shows a circle with centre O in which a diameter AB bisects the chord PQ at the point R. If PR = RQ = 8 cm and RB = 4 cm, then find the radius of the circle. -Maths 9th

Description : The given figure shows a circle with centre O in which a diameter AB bisects the chord PQ at the point R. If PR = RQ = 8 cm and RB = 4 cm, then find the radius of the circle. -Maths 9th

Last Answer : Let r be the radius, then OQ = OB = r and OR = (r - 4) ∴ OQ2 = OR2 + RO2 ⇒ r2 = 64 + (r-4)2 ⇒ r2 = 64 + r2 + 16 - 8r ⇒ 8r = 80 ⇒ r = 10 cm
