Matching the Ending
As an adjective, 'atento' changes its ending to match the person or thing it describes: atento (masculine singular), atenta (feminine singular), atentos (masculine plural), atentas (feminine plural).
Using 'a'
When you say what someone is attentive to, you almost always need the little word 'a' (to/at): 'atento a la pantalla' (attentive to the screen).

Mistake: "Estaba atento el programa."
Correction: Estaba atento **al** programa. (You must use 'a' before the thing you are focused on.)
