The number of the isotope, of course, is the sum of the protons + neutrons. This makes the net charge of an atom zero. 69 protons/electrons. The atomic number is the number of protons in an atom. Atoms of the same element with different numbers of neutrons. A)zero B)1.4 10-17 C C)2.5 10-17 C D)1.1 10-17 C E)3.5 10-18 C Erbium is considered to be moderately toxic. Neutrons form in stars by the fusion of protons, but can also appear in the beta decay of atoms during nuclear fission. Neutrons, like protons have an atomic mass, but lack any charge, and hence are electrically neutral in respect to electrons. Also used to make infrared-absorbing glass and in alloys with titanium. Protons have positive electric charge, neutrons are neutral, and electrons are negative. 2 protons/electrons, 2 neutrons (lightest noble gas) (when stripped of electrons, is called an alpha particle) Lithium Li. An ion is a charged atom with more or fewer electrons than protons. How many protons and nuetrons does the gold nucleus contain? Atomic nucleus diagram labeled with electron, proton, and neutron.
