The ion Ce(3+) of the isotope Ce-140 has 58 protons, 82 neutrons and 55 electrons.
Magnesium has 12 protons and electrons and 12, 13 or 14 neutrons, depending on the isotope.
Protons: 20 Electrons: 18 Neutrons: 21
Fe 2+ (Iron) has... 26 protons 24 electrons 30 neutrons
29 protons and 27electrons are present in Cu2+ ion.
The mass number of an atom is the number of protons plus the number of neutrons. This is is the same as the number of electrons plus the number of neutrons since the number of protons is the same as the number of electrons in an atom.
protons plus neutrons
23 electrons, 26 protons, 30 neutrons.
Magnesium has 12 protons and electrons and 12, 13 or 14 neutrons, depending on the isotope.
Protons: 20 Electrons: 18 Neutrons: 21
The number of protons is 30, the number of electrons is 28, the number of neutrons is different for each isotope.
20 protons, 18 electron's, and 20 neutrons
Fe 2+ (Iron) has... 26 protons 24 electrons 30 neutrons
29 protons and 27electrons are present in Cu2+ ion.
Protons- 30 Electrons- 30 Neutrons- 35 Zn-65 means the atomic number plus the number of neutrons equals 65. Zinc always has 30 protons; therefore, it's atomic number is 30 and it has 30 protons and electrons. The remaining number is the neutrons: 65-30= 35
I don't want to do your homework for you. Here's how you figure it out: Protons = atomic number Neutrons = atomic mass - atomic number Electrons = atomic number + ionization
The mass number of an atom is the number of protons plus the number of neutrons. This is is the same as the number of electrons plus the number of neutrons since the number of protons is the same as the number of electrons in an atom.
The Atomic Mass number of an element is the sum of the protons and neutrons in the nucleus of an atom of that element.The relative atomic mass is the average atomic mass number of all the known isotopes of an element.
