What unit is electronegativity measured in?

A Type I statistical error occurs when a researcher claims that there is not enough support to establish significance for the research hypothesis, but in fact there is enough. True or False

Which of the following describes the products of a chemical reaction? A. The original materials B. The chemicals on the right side of a chemical equation C. The chemicals on the left side of a chemical equation D. The substances that are changed

What does it mean when we say an atom has decayed?

The first excited state of a particular atom in a gas is 5.2 eV above the ground state. A moving electron collides with one of these atoms, and excites the atom to its first excited state.
