All atoms of the same element have the same number of protons, which is its atomic number. A neutral atom will have the same number of electrons as protons.
Boron (symbol B, atom number 5) is build up with:5 protons, 5 electrons and 5 or 6 neutrons, depending on the mass number of the two possible isotopes: B-(10) has 5 neutrons and B-(11) has 6 of them respectively.
Protons and neutrons are found in the center of the atom in a core called the nucleus. Electrons are found in a cloud that continually moves around the nucleus
What is a symbol of 50 protons and 46 electrons?

Sulfur is a chemical element with the symbol S and atomic number 16. It has 16 protons, 16 neutrons and 16 electrons.
Here is the isotopic notation for carbon 14. From looking at the isotopic notation, you can find the number of protons, neutrons and electrons in an atom. Protons- The atomic number is 6, so there are 6 protons Electrons- If the atom is neutral the number of protons equals the number of electrons, so there are also 6 electrons Neutrons- The mass number equals the number of protons + neutrons, and 14-6 leaves 8 neutrons 14 C 6
Potassium and it has 19 electrons and protons and 20 neutrons. Potassium and it has 19 electrons and protons and 20 neutrons. Potassium and it has 19 electrons and protons and 20 neutrons.

- The atomic symbol is only an abridged form of the name of a chemical element. - The chemical symbol of neon is Ne; the atomic number is 10. - The atomic number is equal to the number of protons and electrons. - Number of neutrons = Atomic mass of an isotope - Atomic number
There are a variety of isotopes that have 30 neutrons. It isn't the number of neutrons that determines an element, but the number of protons. Electrons generally balance the number of protons.
All atoms of the same element have the same number of protons, which is its atomic number. A neutral atom will have the same number of electrons as protons.
So, all you have to look at is at the atomic number of the elements on the periodic table, which it is at the top of the symbol on the P.T, and that is the number of protons and electrons! Now, to find the number of neutrons, you have to find the number at the bottom of the element symbol called the atomic mass no. and you take away that by the top number.
