What is the nuclear charge of an atom of NA 23?
It contains seven electrons in orbitals around the nucleus. Its atomic number is its number of protons. Its atomic mass is the mass of protons and neutrons. An atom of sodium-23 (Na-23) has a net charge of +1.
What atom has a mass of 23?
sodium
The mass number is given at the top left of the elements symbol, for example, sodium has a mass number of 23. We know that the atomic number of sodium is 11. This tells us that sodium has 11 protons and because it is neutral it has 11 electrons.
How do you find the nuclear charge?
The equation for calculating nuclear charge is Zeff = Z – S, where Zeff is the effective nuclear charge, Z is the number of protons, and S is the number of inner electrons.
What has an atomic mass of 23 and 11 protons?
The number of protons is equal to the number of electrons. So sodium has 11 protons and 11 electrons. The mass number is 23.
What is the mass of sodium-23?
22.989770

How many electrons with L 2 are there in an atom having atomic number 23?
Thus there are 10 electrons withl=2 in an atom.
What is the nuclear mass?
[′nü·klē·ər ′mas] (nuclear physics) The mass of an atomic nucleus, which is usually measured in atomic mass units; it is less than the sum of the masses of its constituent protons and neutrons by the binding energy of the nucleus divided by the square of the speed of light.
What is the atomic number of a neutral atom with 11 protons 12 neutrons and 11 electrons?
What is the atomic number of a neutral atom with 11 protons 12 neutrons and 11 electrons? We know that the atomic number of sodium is 11. This tells us that sodium has 11 protons and because it is neutral it has 11 electrons.
How many protons neutrons and electrons are in sodium atomic 11 mass 24?
Sodium-24 is composed of 11 protons, 12 neutrons, and 11 electrons. Sodium-24 is one of the most important isotopes. It is radioactive and created from common sodium-23 by neutron bombardment.
