D. Charge

Answer 1

Answer:

Hardness

Explanation:

i think this answer is very helpful for your question .

Answer 2

Answer:

The one key physical property to help differentiate between poor and transition metals is Hardness.

Explanation:

• Hardness can be defined as the ability to resist change in shape or any deformation.

• Transition metals are more hard than poor metals.

• Hardness can be determined by standard measurement of surface resistance to indentation.

• The texture of poor metals are softer than metals which can easily be physically determined.

• Examples of transition metals include gold, silver, copper, iron, nickel etc.

• Examples of poor metals are lead, aluminium, tin, gallium etc.

• Reactivity, Atomic mass and charge are more of an intrinsic property.
