How many number of valance electrons in beryllium?
I might be wrong but: I know that beryllium has two electrons total and the first ring can only fit two electrons so the number of valance electrons is most likely two. Please correct me if I'm wrong.
How many electrons does an atom potassium havew?
Finding the number of electrons in an atom is easy. You just have to know the atomic number of the element. The atomic number for Potassium is 19. That means Potassium has 19 electrons.
How do you determine the number of valence electrons if you know the group no of elements?
valence electrons are electrons at the outermost shell as we all know, group in PE can be determined by looking at the valence electron thus if it is in group 1..then the valence electron is 1
What is the total number of protons neutrons and electrons in Na2SO4 assuming 23Na 32S and 16O?
We know that sodium is atomic number 11, and it has 11 protons, 11 electrons (in a neutral atom), and will have 12 neutrons in its sodium-23 isotope. Sulfur is atomic number 16, and will have 16 protons, 16 electrons (in a neutral atom), and will have 16 neutrons in it sulfur-32 isotope. Oxygen has atomic number 8, and has 8 protons, 8 electrons (in a neutral atom) and will have 8 neutrons in its oxygen 16 isotope. If we take 2 sodium atoms, a sulfur atom and 4 oxygen atoms, we'll have a total of 70 protons, 72 neutrons and 70 electrons in sum.
How can we calculate the atomic number bet we can't see the electrons?
We don't need to. The atomic number is based on the number of protons. Since all elements as they appear in the periodic table have the same number of protons and electrons, if we know one, we know the other.

How calculate electrons?
To calculate the number of electrons, you need to know the total charge of the system or material in question and the charge of a single electron (approx. -1.6 x 10^-19 coulombs). By dividing the total charge by the charge of a single electron, you can determine the number of electrons. Formula: Total number of electrons = Total charge / Charge of a single electron.
What is the total number of electrons in all of the energy cells in an Si atom?
"Energy cells" is non-standard terminology, and I don't know what you meant by it. A neutral silicon atom has 14 electrons in total, if that helps.
What is the total number of valence electrons in a fluorine atom you n the ground state?
An atom of fluorine has 9 electrons in total. Electrons are equal to protons when the atom isn't an ion, and the number of protons is also the atomic number of the element, so you just need to know the atomic number to find out the number of electrons or protons.
How do you find the number of electrons in an atom if you know the number of protons and neutrons?
In a neutral atom, the number of electrons is equal to the number of protons of the nucleus.
How do you calculate number of electrons required for the reaction?
For each element, the number of protons it has is equal to the number of electrons it has. However, if the atom has a different amount of electrons, then the charge will tell you that. If the charge is negative (-) then that says how many electrons the atom has gained, and if the charge is positive (+) then that says how many electrons the atom has lost.
How do you know how many electrons an element has?
atomic number
How many electrons in Sodium Oxide?
Sodium oxide has the chemical formula of Na2O. To find the number of electrons in this molecule, we first need to know the number of electrons for each of its constituent atoms. The number of electrons in a neutral sodium atom is 11 and the number of electrons in a neutral oxygen atom is 8. So, after doing some simple arithmetic, we find that sodium oxide has 2*11 + 1*8 = 30 electrons per molecule.
If you know the number of electrons in a neutral atom can you determine what the element is?
Yes, in a neutral atom the number of electrons and protons is equal, and it is the number of protons that determines what element the atom is. So, by looking at the number of electrons you can tell what element it is.
How do you know how many electrons argon has?
Argon has 18 electrons because it possesses 18 protons in its nucleus, making it electrically neutral. The number of electrons in an atom is equal to the number of protons in the nucleus.
How many electrons does an atom potassium havew?

How many electrons are in mendelevium?
101 electrons...to find the number of electrons in an element, you need to know the number of protons. There are the same amount of protons as electrons. The number of protons is the same number as the atomic number. Mendelevium has 101 as its atomic number therefore 101 protons and therefore 101 electrons.
