What does Χ mean?
Χ is the capital form of Chi, letter 22 of 24 in the Greek alphabet (pronounced KY). Its lowercase counterpart is χ. In science and maths it is used for: Chi-squared distribution, electronegativity. Capital Chi looks the same as the Latin capital X, so LaTeX has no separate command for it — write X (or \mathrm{X}) in math mode.
