Tips

usage
tán covers anything that snaps, springs or vibrates back: 弹钢琴 (play piano — fingers flicking keys), 弹簧 (a metal spring), 反弹 (bounce back / market rebound), 弹性 (elasticity). The formal sense 'to impeach' in 弹劾 also takes tán — historically 'to flick / level an accusation at' an official.
mistakes
Two compounds catch learners out: 动弹 'to budge' takes a toneless tan (neutral tone in CEDICT), not dàn — there's no projectile involved. And 弹涂鱼 'mudskipper' is tán because the fish flicks itself across mud, not because it's bullet-shaped.

Components

radical
gōng
bow
Left bow radical — same indexing semantic as the dàn reading. For tán the bow codes the ACTION: drawing and releasing a string, the snap of cotton-bow fluffing, the flick that launches a pellet. Same family: (draw a bow), (bowstring), (arc).
phonetic
dān
single (here phonetic)
Right supplies the sound — for the tán reading the phonetic has drifted further (dān → tán, both initial and tone shift). Simplified from traditional whose phonetic shows the same drift in (cicada) — same series, tone and initial both moved.
