What are the particles called in a current?

An object in the solar system orbits the Sun and has enough mass that its gravity has pulled it into a spherical shape, but it does not have enough gravity to clear its neighborhood of orbiting debris. This object is classified as:

An infinitely long line of charge has linear charge density 5.00 10-12 C/m. A proton (mass 1.67 10-27 kg, charge + 1.60 10-19 C) is 18.0 cm from the line and moving directly toward the line at 1.20 103 m/s.

An unknown material, m1 = 0.45 kg, at a temperature of T1 = 91 degrees C is added to a Dewer (an insulated container) which contains m2 = 1.3 kg of water at T2 = 23 degrees C. Water has a specific heat of cw = 4186 J / (kg⋅K).
