Solution A Ca atom has two valence electrons, while a Cl atom has seven electrons. A Cl atom needs only one more to complete its octet, while Ca atoms have two electrons to lose. Thus we need two Cl atoms to accept the two … WebWhat actually happens when we perform the double slit experiment and record its outcome on a screen, is that we are making a measurement. When an electron is observed it's wave function collapses except at that point, thus the electron exists only at said point and the observation is made.Before the measurement, the electron exists at multiple places at … flights today from burlington to dc
