What isotope has 18 protons 20 neutrons and 18 electrons?
Explanation: You gots Z=18 , the atomic number, where Z is the number of nuclear protons. The number of protons defines the element….and thus we got calcium…. ….and with 20 neutrons we got the 38Ca isotope….the which is rather short-lived….

When an atom has 6 protons 6 electrons and 8 neutrons What is the charge?
When protons equal electrons the atom is neutral. When protons are greater than neutrons the atom is a positive charge or cation. When the protons are less than the electrons the atom is a negative charge or anion. For this example the Carbon atom has 6 protons and 6 electrons making it neutral.
What has 19 protons and 21 neutrons and 18 electrons?
What atom has 17 protons and 18 neutrons and 17 electrons?
