Manganese: 25 protons, 30 neutrons, 25 electrons. Magnesium: 12 protons, 12 neutrons, 12 electrons. Argon: 18 protons, 22 neutrons, 18 electrons. Potassium: 19 protons, 20 neutrons, 19 electrons. Gold: 79 protons, 118 neutrons, 79 electrons. Hydrogen: 1 proton, 0 neutrons, 1 electron. Fluorine: 9 protons, 10 neutrons, 9 electrons. Silicon: 14 protons, 14 neutrons, 14 electrons. Boron: 5 protons, 6 neutrons, 5 electrons. Bromine: 35 protons, 45 neutrons, 35 electrons.
An element must always have the same number of protons as it's atomic number. The number of electrons may vary, making an atom into an ion, and the number of neutrons can also vary which is why we have different isotopes of the same element.
1 proton,1electron and no neutron
They both have neutrons, protons and electrons.
The weak interaction is capable of converting protons into neutrons plus anti-electrons.
18 protons 18 electrons 22 neutrons
The number of neutrons will vary depending on the isotopes of hydrogen and oxygen in the molecule. The number of protons and electrons will be 10 each in every molecule.
Every nucleus (except for Hydrogen) consists of protons and neutrons. The hydrogen nucleus is only a proton.
An atom contains protons and neutrons in the nucleus (though Hydrogen does not have neutrons) and electrons orbiting the nucleus.
A water molecule has two hydrogen atoms and one oxygen atom. The proton, neutron and electron count of them are 1,0,1 and 8,8,8 respectively. Therefore a molecule of water has 10 protons, 8 neutrons and 10 electrons.
There will be a total of 10 protons and 10 electrons (one from each hydrogen and eight from oxygen). The number of neutrons depends on the isotope of hydrogen and oxygen. And for the most stable isotopes of hydrogen and oxygen, there will be 10 neutrons in H2O.
