Atom neutral electrical charge will be prachubuak deleted. Displays the number of protons in an atom is equal to the number of protons in an atom the electrons, which have an "atomic number". Number of protons = number of electrons Proton to neutron is heavy particle relative to the electron. Thus, the mass of an atom is the number of protons, neutron that is combined with the number of "mass numbers." Mass number = number of protons + number of neutron. We can write as a symbol to indicate the atomic number and mass number, as follows: When A replacement mass number. Instead, atomic number Z X represents the symbol of the element For example, Atomic number = number of protons = number of electrons. 11 = number of protons = number of electrons Mass number = number of protons + number of neutron. 23 = 11 + neutron count Neutron count = 23-11 = 12 That is, that have the same number of protons, electrons and sodium neutron is equal to 11, 11, and 12, respectively.
