Rust works in the same was as a battery.
It requires a cathode an Anode and a path between the two.
While grease may slow the process by helping to block the path it will not prevent rust. Rust is prevented by applying a an anode to the metal, such as zinc to iron. The zinc will more readily give up it's electrons than will the iron thus preventing the rusting of the the iron Rust is the oxidation of iron. Grease simply becomes a barrier between the oxygen in the air and the iron. Other methods of this application includes oil, paint and plastic coating to prevent iron from rusting.

RafaOil creates a barrier between iron and oxygen in the air, preventing the moisture from coming into direct contact with the iron surface. This barrier inhibits the oxidation process, which is a key factor in rust formation. Therefore, oil helps to protect iron from rusting by acting as a barrier against moisture and oxygen.
Zinc is a more reactive metal in the electrochemical series than iron. For iron to corrode it needs to react thus: Fe ---->Fe +2e- . However, zinc is more reactive and produces electrons even more easily. Zn---->Zn +2e- and these electrons suppress the production of electrons by iron. In other words, zinc sacrifices itself as an anode to cathodically protect the iron. This is known as SACP - sacrificial anode cathodic protection.
If a scratch appears in the zinc coating, the scratch quickly fills with zinc corrosion products protecting the iron. This is the basis of protecting iron or steel by galvanizing and zinc rich paints.
Some metals are more prone to corrosion than others. Zinc is more prone to oxidization than either copper or iron. It is therefore, used as a sacrificial metal which will corrode and create a protective coating of zinc oxide/hydroxide/carbonate over the iron core protected by the galvanizing. On boats with bronze propellers or iron hulls (or both), zinc bars are attached to the hull. The zinc bars corrode instead but need to be replaced regularly.
Sometimes a mild electric charge is applied, to prevent the corrosion to the hull or propellers. This is called ICCP -impressed current cathodic protection.

What are the elements is used to protect iron from rusting and has good electrical conductivity?
One element that can protect iron from rusting and has good electrical conductivity is zinc. Zinc can be used as a sacrificial coating on iron surfaces through a process called galvanization, where the zinc layer corrodes instead of the iron. This protects the iron from rusting while providing good electrical conductivity.
How can iron be treated to stop it from rusting?
cover in oil, paint, grease or plastic. or galvanise it
What is one kind of an atom used to protect iron atoms from rusting?
Zinc atoms are commonly used to protect iron from rusting through a process called galvanization. When zinc atoms are attached to the surface of iron, they act as a sacrificial anode, corroding first instead of the iron, thus preventing rust formation.
