WebWhen the vaporised organic sample passes into the ionisation chamber of a mass spectrometer, it is bombarded by a stream of electrons. These electrons have a high enough energy to knock an electron off an organic molecule to form a positive ion. This ion is called the molecular ion - or sometimes the parent ion. WebHow do you find isoelectronic atoms? Step 1: Count the number of electrons in the neutral atoms given. Step 2: If the atom is an ion, add or subtract the correct number of electrons from the number of electrons in the neutral atom. Step 3: Compare the number of electrons in each pair of atoms to confirm they are isoelectronic.
