The following are some statements about Mendeleev's peridioc table (i) It is based on increasing order of atomic numbers . (ii) Mendeleev corrected the atomic weight of some elements like Be, In, U, etc. (iii) (Ar, Ca), (Co, Cu), (Te , F) are three inverted pairs. (iv) it is based on increasing order of atomic weights.

A mole of any substance contains 6.023xx10^(23) particles. The particles may be atom, molecule ions, electron, proton or neutron. One mole of atom is equal to 1 gm -atom which is equal to atomic weight of atom. 1 gm molecule of any gas is 1 mole of gas whose volume is 22.4 litre at N.T.P. Mass of 1 atom of an element X_(2) is 6.64xx10^(-23)gm . Molecular weight of X_(2) is

When 6 xx 10^22 electrons are used in the electrolysis of a metallic salt, 1.9 gm of the metal is deposited at the cathode. The atomic weight of that metal is 57. So oxidation state of the metal in the salt is

An alloy is composed of two radiactive materials A and B having equal weight. The half life of A and B are 10 yrs and 20 yrs respectively. After time t, the alloy was found to consist of (1/e) kg of A and 1 kg of B. If the atomic weight of A and B are same, then the value of t is (Assume, ln 2=0.7 )
