There are different electrons in the outer shell of each element.
Helium is the element in the noble geses family that does not have an octet. Helium is the element in the noble geses family that does not have an octet.
The outer shell (N=4) of the copper element has 2 electrons.
It is Oxygen. Because Oxygen has the atomic no. - 8. Which means that 2 electrons can accommodate in the inner shell and the rest of the electrons (6 electrons) are in the out shell.
When an atom forms an ion, the outer shell of the ion will have gained or lost electrons to achieve a full valence shell. For cations (positive ions), the outer shell will have fewer electrons than the neutral atom. For anions (negative ions), the outer shell will have more electrons than the neutral atom.
The calcium atom has 2 outer shell electrons. It's configuration is: [Ar] 4s2 it also has 2 inner shell electrons
The element with 6 outer shell electrons is carbon. Carbon has 4 electrons in its outer shell and 2 electrons in the shell before that, totaling 6 outer shell electrons.
Boron has 3 electrons in the outer shell and 2 electrons in the inner.
The outer shell (N=4) of the copper element has 2 electrons.
There are different electrons in the outer shell of each element.
Helium is the only noble gas that does not have eight electrons in its outer shell. It has only two electrons in its outer shell.
The element with 54 electrons is Xenon (Xe). Xenon is an Inert Gas in Period 5 of the Periodic Table. Xenon has 54 electrons in 5 shells with 8 electrons in the outer shell.
Helium is the element in the noble geses family that does not have an octet. Helium is the element in the noble geses family that does not have an octet.
The periods in the periodic table tell you the energy level where the last electrons are being added. So, in period 1, the outermost electrons are in the first energy level or shell. In the 3rd period, the outermost electrons reside the the 3rd energy level, and so on.
The element with atomic number 28 is Nickel (Ni). It is a transition metal in period 4 of the Periodic Table. It is the first element in the Nickel family. It has 28 electrons in 4 shells with 2 electrons in the outer shell.
Elements in Group 1 of the periodic table have one electron in their outer shell, while elements in Group 2 have two electrons in their outer shell. This configuration makes these elements more stable and likely to form ions with a positive charge by losing these outer electrons to achieve a full outer shell.
Curium, as an actinide element, has 4 electrons in its outermost shell (shell 7).
