Protons = 17; Electrons = 17; Neutrons = 19
A nitrogen atom has 7 protons, 7 electrons and 7 neutrons for the most common isotope
Cl-35 isotope has 18 neutrons Cl-37 isotope has 20 neutrons
The atomic number of francium is 87. This means that it has 87 each of protons and electrons. The number of neutrons depends on the isotope, but the most common one, Fr-223, has 223 - 87 = 136 neutrons. (The number of neutrons is always the isotope mass number minus the atomic number.)
Indium, (In) atom number 49, has:49 protons (same as atom number)49 electrons (same as protons in the UNcharged neutral atom)113-49=64 neutrons in In-113 isotope or 115-49=66 neutrons in In-115 isotope,both are natural occurring isotopes of In (5% and 95% respectively).
The number of neutrons is the difference between the atomic mass of an isotope and the atomic number. Actinium has a great number of isotopes, each with a different mass or number of neutrons.
A nitrogen atom has 7 protons, 7 electrons and 7 neutrons for the most common isotope
Radium has 88 electrons. The number of neutrons is different for each isotope: Number of neutrons = Atomic mass of an isotope - 88
Boron has 5 electrons and protons; the number of neutrons is specific for each isotope. Number of neutrons in a boron isotope = Mass number - 5
The isotope carbon-12 has 6 protons, neutrons and electrons.
Promethium has 61 protons and electrons; For each isotope the number of neutrons is different. Number of neutrons = Mass number of an isotope - 61
Cl-35 isotope has 18 neutrons Cl-37 isotope has 20 neutrons
Oxygen has 8 electrons and protons. The number of neutrons is different for each isotope: Number of neutrons = Atomic mass of the isotope - Number of protons
The atomic number of francium is 87. This means that it has 87 each of protons and electrons. The number of neutrons depends on the isotope, but the most common one, Fr-223, has 223 - 87 = 136 neutrons. (The number of neutrons is always the isotope mass number minus the atomic number.)
The natural isotope of carbon 13C (abundance 1,1 %) has 6 protons, 6 electrons and 7 neutrons.
Indium, (In) atom number 49, has:49 protons (same as atom number)49 electrons (same as protons in the UNcharged neutral atom)113-49=64 neutrons in In-113 isotope or 115-49=66 neutrons in In-115 isotope,both are natural occurring isotopes of In (5% and 95% respectively).
Technetium has 43 protons and 43 electrons. For each isotope the number of neutrons is different. Number of neutrons = Mass number of an Tc isotope - 43
Number of Protons = Number of electrons = 17.The number of neutrons depends on the isotope. Cl-35 and Cl-37 isotopes have 18 and 20 isotopes respectively.
