They can ONLY move slower than the speed of light.
the wave front of electric current. the electrons themselves move much slower but they keep pushing electrons ahead of them on resulting in a wavefront that moves at almost the speed of light.
Nothing that has mass when it's stationary can move at the speed of light. Electrons can move at any lesser speed. In modern particle accelerators, they can be boosted to 0.99999c. But every additional ' 9 ' requires ten times as much energy as the previous one did.
No but the leader that travels from the cloud to the ground travels at about 60 000 m/s. Light travels at 300 000 000 m/s. Note that the bright flash of lightning occurs on the return stoke and travels from the ground up to the cloud. Read the article on lightning at Wikipedia.org, 'The World's Encyclopedia'.

No. Three types of speed must be distinguished here: 1. The random movement of electrons is pretty fast, but still only a fraction of the speed of light. They will have this movement, whether there is a current or not. 2. The drift velocity is the average velocity of electrons when there is a current. This velocity is typically a fraction of a millimeter per second. 3. The velocity of the electric signal itself is typically about 2/3 the speed of light in a vacuum (that is, about 200,000 km/sec). What happens here is that energy is transferred from one electron to another. Imagine one electron bumping into another and pushing it forwards.
Light moves slower in air than in a vacuum because air molecules and atoms can interact with the electromagnetic waves of light, causing them to scatter and slow down. In a vacuum, there are no particles to interact with, so light can move through it at its maximum speed of approximately 299,792,458 meters per second.
No, because the orbital is really just an abraction - the electron isn't racing around the orbital like a racecar, so there isn't a speed. The orbital is a better measure of the electrons potential energy.
No. Because of their mass, they travel slower than c.
Nothing can be made to move faster than the speed of light in a vacuum; for objects that move slower than light, even reaching the speed of light would require an infinite energy.
Yes, typically about 2/3 of the speed of light in a vacuum - that is, about 200,000 km/sec. Note that the drift speed of the electrons is only a fraction of a millimeter per second, and the random speed of electrons is faster, but still much slower than the speed of the CURRENT.Yes, typically about 2/3 of the speed of light in a vacuum - that is, about 200,000 km/sec.

The electrical current (or signal) travels at about 2/3 the speed of light in a vacuum - that is, it travels at approximately 200,000 km/sec. Note that individual electrons move slower than that.
The speed of light in a vacuum is 300,000 kilometers per second (or 300 million meters per second). In a vacuum, light can ONLY move at that speed - neither faster, nor slower.
electrons (near light speed)
No, they are not.Gamma rays are photons - just like light. They are electrically neutral. They move at the speed of light. Positrons, also known as anti-electrons, have a positive charge. They move at speeds less than the speed of light.
