Often, the number of protons and electrons is not the same, so the atom carries a net positive or negative charge. You can determine the number of electrons in anionif you know its charge. A cation carries a positive charge and has more protons than electrons. An anion carries a negative...

IN the theory of 尾-decay as proposed by Fermi, one assumes the existence of elementary processes in which a neutron is transformed into a proton by simultaneous creation of an electron and a neutrino. For the inverse process, which is also naturally contained in Fermi's theory, one needs ...
Neutrons are subatomic particles found in the nucleus of an atom, alongside protons. They are electrically neutral, lacking a net electric charge, which distinguishes them from positively charged protons and negatively charged electrons. Neutrons play a crucial role in the stability of the nucleus, ...

Plugging in 17 for protons (p+) and -1 for the charge gives: #e−+17=−1 So: #e−=18 Thus, a chlorine ion has 18 electrons. Finding the Number of Subatomic Particles in Isotopes Isotopes are forms of the same element with different numbers of neutrons. The number of protons ca...
