Notes consist of the head the stem and the flag or beam.
Stems Stems are notated on the right side of the notehead and are ascending if the notehead is on the 3 line of the staff or below that line. Stems are notated on the leftside of the notehead and are descending if the note is on the 3rd line of the staff or above that line. Flags Flags are notated to the right of the stem whether the stem is on the right or left side of the note head. Beams Notes should be beamed together to show the beat. Beams should therefore not cross beats.
