笑 (xiào) covers what English splits into 'to laugh' and 'to smile' — any pleasant expression involving the mouth turning up, with or without sound.
Context tells you which: 她笑了 can mean 'she smiled' or 'she laughed.' To be specific, Chinese adds another character: 微笑 (wēixiào, 'smile gently'), 大笑 (dà xiào, 'laugh loudly'), 哈哈大笑 ('to roar with laughter'). 笑 also has a darker side — 笑 someone usually means 'to laugh AT' them, i.e.
mock or ridicule: 别笑我 ('don't laugh at me'). Common related words: 开玩笑 (kāi wánxiào, 'to joke / kidding'), 笑话 (xiàohua, 'a joke'), and the warm phrase 笑容 (xiàoróng, 'a smiling expression'). The character contains 竹 (bamboo) on top — bamboo bending the way a face bends in laughter.

written
Specifically 'to smile (without sound).' Use 微笑 when you want to make clear it's a quiet smile, not a laugh. 笑 alone is ambiguous; 微笑 is precise.
笑容 is the noun 'smile / smiling expression' — what's ON your face. 她脸上有笑容 ('she has a smile on her face'). 笑 is the verb of doing it.
哭 is the opposite — 'to cry.' Both are basic emotion verbs: 笑 (laugh/smile) vs 哭 (cry). The character 哭 has 口 (mouths) and looks like a tearful face.
嘲笑 specifically means 'to mock / ridicule.' 笑 someone CAN mean mock, but in context. 嘲笑 is unambiguous ridicule. Use 嘲笑 in formal writing about bullying or sarcasm.
