1) Preliminar explanation:
Atoms are neutral spieces: they have the same number of positive charges (protons inside the nucleous) as of negative charges (electrons around the nucleus).
Ions are formed by the gain or loss of electrons.
Positive ions are formed when neutral the atoms lose electrons, and negative ions are formed when neutral atoms gain electrons. Only the elctrons are gain or loss in ions formation (the number of protons remain unchanged).
2) Conclusion (answer)
Therefore, mathematically an ion is the result of adding or subtracting electrons to an atom, creating an imbalance of charge, positve when the atom ends up with less electrons than protons (loss of electrons) or negative when the atoms ends up with more electrons than protons (gain of electrons).
Answer:
Explanation:
According to legend, Galileo dropped weights off of the Leaning Tower of Pisa, showing that gravity causes objects of different masses to fall with the same acceleration. In recent years, researchers have taken to replicating this test in a way that the Italian scientist probably never envisioned — by dropping atoms. One of Galileo's contributions to the founding of modern science was his study of falling objects. He turned, then, to measuring the acceleration of objects rolling down smooth ramps. The ramp "diluted" the acceleration to a value small enough to allow accurate measurements of the longer time intervals.
