Question

What is the oxidation state of a lone element?
O A. It is its most likely oxidation state.
O B. It is always 1.
O C. It is always 0.
O D. It is the same as in a compound.

Answer 1

Answer:

The oxidation state of hydrogen is +1 in its compounds, except for metal hydrides, such as NaH, LiH, etc., in which the oxidation state for H is -1. The oxidation states of other elements are then assigned to make the algebraic sum of the oxidation states equal to the net charge on the molecule or ion.

Answer 2

The oxidation state of a lone element is that It is its most likely oxidation state, and it is the same as in a compound. The correct options are A and D.

What is an oxidation state?

The oxidation state or oxidation number is a hypothetical charge that is given to the elements when they lose or gain an electron. When elements combine, they form bonds with each other. When bonds are formed, the atoms share electrons with each other.

The element that gains electrons, get a negative charge, and the atom that donates electrons gain a positive charge. The number of charges increased as per electrons. The oxidation state of a lone element is most likely the oxidation state and the same as in a compound.

Thus, the correct options are A. It is its most likely oxidation state and D. It is the same as in a compound.
