Using the Periodic Table you are able to determine the number of protons, electrons, and neutrons for any of the elements identified to this date. Knowing an element's name or symbol, look up the element in the table. For example lets look up Boron! Boron's chemical symbol is B, and from the periodic table its atomic number is 5. The atomic number of an element reveals the number of protons and also the number of electrons the element has as a single isolated atom. Although, the element may not exist freely as an isolated single atom in nature.
So, Boron has 5 protons and 5 electrons. The number of neutrons an element may have can vary, and this is what differentiates stable and unstable isotopes of many elements. Boron has a molar mass of 10.811, and is listed with two stable isotopes: 10B and 11B. Subtracting the atomic number from the isotope number gives the number of neutrons boron is found with. The 10B isotope has 5 neutrons, and the 11B isotope has 6 neutrons. Since the molar mass is 10.811, we can tell that the 11B isotope is more abundant than the 10B isotope. If the distribution was equal then the molar mass would be 10.5.
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
A nitrogen atom has seven electrons.
To find the valence electrons in an atom, look at the group number on the periodic table. The group number tells you how many valence electrons an atom has. For example, elements in group 1 have 1 valence electron, elements in group 2 have 2 valence electrons, and so on.
A germanium atom has 32 electrons.
An atom of selenium has 34 electrons.
Neptunium has 93 protons and electrons.Number of neutrons = Mass number of an isotope - 93
It depends on the atom you are reffering to, but to find the electrons take away the number of protons from the mass number of the atom.
Silver (Ag) has 47 protons, 47 electrons and 61 neutrons, with an atomic number of 47 and atomic mass of 108.
A neutral atom with 49 protons has 49 electrons.
