Question

which of the following groups of elements can have positive as well as negative Oxidation State​

Answer 1

Answer:

F is more electronegative as it belongs to group 17 or 7 and can show only negative oxidation state of –1.

(b) Cesium is highly electropositive and can show only +1 oxidation state as it has only one electron in its valency shell.

(c) I has 7 electrons in its valency shell and can therefore exibit a oxidation state of –1 , How ever since Iodine has empty d orbitals it can also exibit different oxidation state like +1,+3,+5, +7.

(d) Neon is a inert gas and hence do not exibit any oxidation state
