A-levels sentence example

The term ionization energy is a reference to the quantity, or amount, of energy necessary to expel an electron from the gaseous form of an atom or molecule. As electrons are removed, it becomes more difficult to remove another because the charge of the atom has changed, and the electron is more attracted to stay with the atom. As such, different ionization energy can be required under different circumstances. Learn how to properly calculate the quantity of energy required and see ionization energy examples.

Hypothesis testing refers to the process of making inferences or educated guesses about a particular parameter. This can either be done using statistics and sample data, or it can be done on the basis of an uncontrolled observational study.
