A half note is a hollow note head with a stem, and it lasts two beats in common time, half a whole note.
Hollow head means long; a stem halves it. That is the whole system: each added feature halves the value, from whole note to half to quarter to eighth.
How to spot it
An empty oval with a straight line coming off it. Compare it with a quarter note, which is the same shape filled in.
Find it in thirty seconds
Find a half note and a quarter note in the same piece and play them one after the other, counting "one-two" then "one". The difference should be obvious in your hand, not just on the page.
