(a)

Interpretation Introduction

Interpretation:

The maximum positive oxidation state of Ti has to be determined.

(a)

Expert Solution
Check Mark

Explanation of Solution

The number of electron loosed or gained in the formation if molecule is known as oxidation state or number.

The general electronic configuration of Ti is,

1s2 2s2 2p6 3s2 3p6 4s2 3d2

After removal of 4 electrons it is become,

1s2 2s2 2p6 3s2 3p6 4s0 3d0

Not able to remove more electrons from Ti4+, it requires more energy so the maximum positive oxidation state of Ti is +4.

(b)

Interpretation Introduction

Interpretation:

The maximum positive oxidation state of W has to be determined.

(b)

Explanation of Solution

The number of electron loosed or gained in the formation if molecule is known as oxidation state or number.

The general electronic configuration of W is,

1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p6 6s2 4f14 5d4

After removal of 6 electrons it is become,

1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p6 6s0 4f14 5d0

Not able to remove more electrons from W6+, it requires more energy so the maximum positive oxidation state of W is +6.

(c)

Explanation of Solution

The number of electron loosed or gained in the formation if molecule is known as oxidation state or number.

The general electronic configuration of Ta is,

1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p6 6s2 4f14 5d3

After removal of 5 electrons it is become,

1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p6 6s0 4f14 5d0

Not able to remove more electrons from Ta5+, it requires more energy so the maximum positive oxidation state of Ta is +5.

(d)

Explanation of Solution

The number of electron loosed or gained in the formation if molecule is known as oxidation state or number.

The general electronic configuration of Ta is,

1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p6 6s2 4f14 5d5

After removal of 7 electrons it is become,

1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p6 6s0 4f14 5d0

Not able to remove more electrons from Re7+, it requires more energy so the maximum positive oxidation state of Re is +7.
