number in combined state :
(1) Os
(2) Ru
(3) Both (1) and (2) (4) None​

Answer 1

Answer:

hey mate your answer is

Explanation:

Os and Ru have highest oxidation state +8.

@Raj Singh......

Answer 2

Hence, option (3) Both (1) and (2) is correct.

Explanation:

Ruthenium (Ru),

Atomic number = 44

Eectronic configuration: Kr $[4d^{7} 5s^{1}]$

Oxidation  number in combined state = + 8

Osmium (Os),

Atomic number = 76

Eectronic configuration: Xe $4f^{14}5d^{6}6s^{2}$

Oxidation  number in combined state = + 8

Hence, Osmium (Os) and Ruthenium (Ru) have  highest oxidation

number in combined state is + 8.

Hence, option (3) Both (1) and (2) is correct.
