<h2>Answer : Seismic Waves.</h2><h2 /><h3>Explanation : </h3><h3>Vibrations that move through the ground carrying the energy released during an earthquake are called seismic waves.</h3>
Seismic waves are waves of energy which usually travels through the Earth's layers, and as a result release the energy during earthquakes, volcanic eruptions, magma movement, large landslides or large man-made explosions. It is mainly measured through a special instrument called as seismometer and the graph obtained is called as seismograph.
If you mean how many electrons an atom contains then this is the same as the atomic number of the atom. For example, the atomic number of oxygen is 8 so it contains 8 protons. Since in a stable atom, the number of protons is equal to the number of electrons, oxygen contains 8 electrons.
If you have an ion and you want to know how many electrons it has lost or gained, you look at the charge. If it is a 2+ ion then it has lost two electrons, if it's a - ion then it has gained an electron. The number of electrons in an ion is the atomic number +/- the charge shown. For example a Mg2+ ion would have 10 electrons as a magnesium atom has 12 electrons and loses two to form the 2+ ion.
