This depends on multiple conventions, but in a right-handed coordinate system the usual convention is to say spin down for clockwise spin.
Also note that an electron is not really spinning! It is a point-like particle after all!
'Counter-clockwise' requires a reference point such that we can determine which side of the galactic plane one is on to look at the direction of spin. That said, the planets do all orbit in the same direction. Additionally, Venus, Uranus and the Plutoid all spin in different directions than the other planets, which spin the same way as their orbits. Venus spins in the exact opposite direction (retrograde), Uranus has its axis of spin on the galactic plane, and the Plutoid's axis is inclined 123 degrees to its plane of orbit, making its spin retrograde as well.
clockwise
anti clockwise or clockwise - it depends - in North America its clockwise but in the UK it is anti clockwise
LEPTONS are basically family of fundamental subatomic particles consisting of electron, muon, tauon(tau) particles with their corresponding neutrinos They have spin 1/2. They do not strongly interact.
In modern physics, particles can certainly have or be assigned a fractional charge (like quarks with a charge of +/- 2/3) or fractional spin (like the spin 1/2 fermions) but the concept of a fraction of a particle is not recognized. An object gaining six electrons is possible but gaining a half of an electron isn't meaningful. In an abstract sense, two atoms might share an electron in a bond (with covalent behavior) but in reality this would be more like a probability cloud with an electron sharing its "time" partly with one atom and partly with the other.
by looking at it
According to Pauli's Exclusion principle it will be having anticlock wise spin if it is in the same orbital. Because no two electrons can have all the four(always spin is half) quantum number same. By the way, I don't think anyone actually calls them "clockwise" and "counterclockwise". It's usually "up" and "down" or "plus one-half" and "minus one-half".

The spin of an electron is 1/2 because it is an intrinsic property of the electron that determines its angular momentum. This value of 1/2 is a fundamental characteristic of electrons in quantum mechanics.
Most tornadoes in the northern hemisphere spin counter clockwise while most in the southern hemisphere spin clockwise.
They spin clockwise
actually they don't rotate at all (what is clockwise or anticlockwise for an electron anyway? what's the reference frame?). there's no rotation in the subatomic level. even if there were any, we wouldn't be able to detect it. roj
No, normally tornadoes spin clockwise in the southern hemisphere.
Tornadoes nearly always spin counterclockwise if they are in the northern hemisphere and clockwise if they are in the southern hemisphere.
Yes, L-Drago Beyblades can spin in either direction - clockwise or counterclockwise.
Yes. The vast majority of tornadoes in the southern hemisphere spin clockwise.
The two types of motion that electrons exhibit in an atom are orbital motion around the nucleus, and spin motion on their own axis. Orbital motion refers to the movement of electrons in specific energy levels around the nucleus, while spin motion refers to the clockwise or counterclockwise rotation of an electron on its axis.
