How the atomic number related to the core electrons?

The atomic number represents the number of protons in an atom's nucleus, which is also equal to the number of electrons in a neutral atom. Core electrons are those that are closest to the nucleus and are not involved in chemical bonding. The number of core electrons in an atom is equal to the difference between the atomic number and the number of valence electrons.


How can the number of core electrons be determined on the periodic table?

The number of core electrons can be determined from the periodic table by identifying an element's atomic number, which indicates the total number of electrons. Core electrons are those that are not in the outermost shell; for main group elements, this typically includes all electrons in completed inner shells. To find the number of core electrons, you can subtract the number of valence electrons (the electrons in the outermost shell) from the total number of electrons. For example, oxygen (atomic number 8) has 6 core electrons and 2 valence electrons.


How many core electrons does tungsten have?

Tungsten has 46 core electrons. Core electrons are the electrons found in all elements that are not valence electrons. Tungsten has an atomic number of 74, so it has 74 electrons in total.


How do you figure out the core charge of an atom?

The core charge of an atom is determined by subtracting the number of core electrons from the number of protons in the nucleus of the atom. Since core electrons are those in the inner energy levels, the core charge is important in understanding the chemical behavior of an atom.


How does one determine the number of core electrons an atom has?

subtract the group number from the atomic number


How many core electrons in Cl?

The number of core electrons in chlorine is 10.


How many core electrons in nitrogen?

Nitrogen has 2 core electrons and 5 valence electrons. If you remember, nitrogen has an atomic number of 7. When an atom is neutral it has an equal number of protons and electrons. Therfore, the overal number of electrons is 7. The definition of core electrons is, electrons in their most inner shell, On the other hand valence electrons are electrons in the outermostshell. When looking at a periodic table you see that there is a total# of 5 valence electrons. In order to figure out the core number you subtract the total number of electrons(atomic #) - Valence # of electrons. I hope this helped :)


How many core electrons does argon have?

Argon has 18 core electrons. This is because the atomic number of argon is 18, and the number of core electrons is equal to the number of electrons in the nearest noble gas configuration, which in this case is neon (10 core electrons), plus the number of electrons in the next energy level, which is 8 for argon.


How many core electrons does the atom xenon have?

Xenon has 54 core electrons. This is determined by subtracting the number of valence electrons (8 for xenon) from its atomic number (54). Core electrons are those that are not involved in chemical bonding and are found in the inner electron shells.


What atom has 6 valence electrons and 10 core electrons?

Sulfur. It has six valence electrons. These six electrons plus the ten core electrons, 16, the atomic number (number of electrons or the number of protons [they are an equal amount because the positive and negative charges have to cancel each other out]). It is sulfur.
