A cute, round, white cartoon character representing helium, with 'He' on its chest, holding a red balloon.

Create a soft, cartoon-style illustration of a single, round, white character resembling a helium atom. The character should have a happy, friendly face, simple black eyes, and a big smile. On its chest, place the chemical symbol "He" inside a simple atomic orbital (two electrons circling a nucleus). The character is floating gently, holding a red helium balloon by a string. Surround the character with a soft, white, cloud-like glow. The overall art style should match educational illustrations: soft blue tones, clean lines, and a cheerful, approachable look, just like the hydrogen characters in the reference image. See more
