Protons and electrons were discovered toward the end of his life.
Selenium-55 has 34 protons, 21 neutrons, and 34 electrons.
Indium have:protons = 49neutrons = 66electrons = 49to know how to get the protons, electrons and neutrons:protons = atomic number of the elementelectrons = protons or atomic number of the elementneutrons = mass number-atomic number
There are 14 protons and 16 neutrons in 30Si and the atom is a stable isotope of silicon.
Au-197 has 79 protons, 79 electrons, and 118 neutrons. The atomic number of gold (Au) is 79, indicating the number of protons. The isotope Au-197 specifies the atomic mass, which is the sum of protons and neutrons. So, subtracting the atomic number from the atomic mass gives the number of neutrons.

Nothing,Dolton did not know about Protons,neutrons and electrons
2 protons 2 electrons 2 neutrons 2 protons 2 electrons 2 neutrons don't know
Phosphorus has an atomic no. of 15 and its atomic mass is 31.=we know,atomic no.=number of protons==also, atomic mass=no.of protons+no. of neutrons==this implies, 31=15+no. of neutrons= 31-15=no. of neutrons= 16=no. of neutrons==also,no. of protons=no, of electrons=so, total no. of protons=15total no. of electrons=15total no. of neutrons=16
Selenium-55 has 34 protons, 21 neutrons, and 34 electrons.
Several come to mind. They are both found in the nucleus of an atom. Protons have a positive charge, while neutrons have no charge. They are nearly the same size, though neutrons are a bit larger. The sum of the protons and neutrons in an isotope of an element is its mass number.
Indium have:protons = 49neutrons = 66electrons = 49to know how to get the protons, electrons and neutrons:protons = atomic number of the elementelectrons = protons or atomic number of the elementneutrons = mass number-atomic number
Add the number of protons plus the number of neutrons for an approximate answer. Compared to protons and neutrons, electrons have zero mass - it takes over 1800 electrons to equal the mass of a proton or neutron.
6 protons 6 neutrons 6 electrons. If you can use Wikianswers then you should know how to use Google
An atom contain protons, neutrons and electrons.
In a neutral atom, the number of electrons is equal to the number of protons of the nucleus.
There are 14 protons and 16 neutrons in 30Si and the atom is a stable isotope of silicon.
Find the atomic number. That tells you the number of protons and electrons (in a neutral atom). Then find the atomic weight. The number of protons plus the number of neutrons will equal the atomic weight. So if you know the wt. just subtract the number of protons and you will have the number of neutrons.
