STATEMENT-1 : Hg exists in liquid state at room. Temperature
and
STATEMENT-2: Hg has `(n-1)d^(10)ns^(2)` E.C.

The elements which exist in liquid state at room temperature are (1) Na (2) Br_2 (3) Hg (4) Ga

STATEMENT-1: Mercury is liquid at room temperature. STATEMENT-2: In mercury, there is no unpaired d-electron and thus metallic bonding is weakest.

STATEMENT-1: The highest oxidation state of chromium in its compounds is +6. and STATEMENT-2: Chromium atom has only six electrons in ns and (n-1)d orbitals.

Each question has four choices a, b, c and d, out of which only one is correct. Each question contains STATEMENT 1 and STATEMENT 2. Both the statements are TRUE and STATEMENT 2 is the correct explanation of STATEMENT1. Both the statements are TRUE but STATEMENT 2 is NOT the correct explanation of STATEMENT 1. STATEMENT 1 is TRUE and STATEMENT 2 is FALSE. STATEMENT 1 is FALSE and STATEMENT 2 is TRUE. Statement 1: The value of (^(10)C_0)+(^(10)C_0+(10)C_1)+(^(10)C_0+(10)C_1+(10)C_2)++(^(10)C_0+(10)C_1+(10)C_2++(10)C_9) is 10 2^9 . Statement 2: ^n C_1+2^n C_2+3^n C_3+ n^n C_n=n2^(n-1) .
