Thank you

Answer 2

Answer: Osmium is an example of transition element showing +8 oxidation state.

Explanation:

Transition elements are the elements which lie between s and p block elements. The valence electrons of these elements enter d-orbital. Their general electronic configuration is:  $(n-1)d^{1-10}ns^{0-2}$ where n is the outermost shell.

These elements show variable oxidation state because their valence electrons in two different sets of orbitals, that is (n-1)d and ns.

Oxidation state is defined as the number which is given when an element looses or gains electrons.

• When an element looses electrons, it will attain a positive oxidation state and this is mainly shown by metals.
• When an element gains electrons, it will attain a negative oxidation state and this is mainly shown by non-metals.

Transition metal showing +8 oxidation state is Osmium.
