An atom of magnesium has lost two electrons. The atomic mass is carried by the atomic nucleus, which occupies only about 10-12 of the total volume of the atom or less, but it contains all the positive charge and at least 99.95% of the total mass of the atom. See the answer. Well, this one is easy.. For iodine, [math]Z_{\text{the atomic number}}=53[/math]. Iodine is the least abundant of the stable halogens, being the sixty-first most abundant element. 5. Total number of protons in the nucleus is called the atomic number of the atom and is given the symbol Z . A neutral atom has the same number of protons and electrons (charges cancel each other out). protons in the nucleus. And so there are 53 massive, positively charged particles in the element’s nucleus. The chemical symbol for Iodine is I . Iodine is the heaviest of the stable halogens, it exists as a lustrous, purple-black metallic solid at standard conditions that sublimes readily to form a violet gas. The number of protons and electrons in an atom or molecule determines its charge and whether it is a neutral species or an ion. Xenon-124 absorbs a proton and immediately loses a neutron and proton to form xenon-123, or else loses two neutrons to form caesium-123, which decays to xenon-123.
