The first orbit only has an S orbital. The S orbital can hold 2 electron. The second orbit has s and p orbitals. The p orbital can hold 8 electrons The third orbit has s, p, and d orbitals. The d orbital hold 10 electrons giving a total of 18. However the 3d orbital has a higher energy level than 4s so the 4s orbital is filled with electrons before you can put electrons in the 3d orbital. The fourth orbital has s,p,d,and f. The f orbital can hold 14 electrons. This gives a total of 32 electrons. However the 4f orbital is higher in energy than the 5s, 5p, and 62 orbitals. Therefore these orbitals must be filled first. The fifth, sixth and seventh orbitals are similar to the fourth.
Yes, valence electrons are the electrons in the outermost energy level or orbital of an atom. These electrons are involved in determining the chemical properties of an element and its ability to bond with other atoms.
Helium (He) and Neon (Ne) will both have their outer energy level filled with 2 electrons.
The electrons in the outermost orbital used in chemical bonding are called valence electrons. They are involved in forming bonds with other atoms to complete the octet rule and achieve stability.
Copper has an electron configuration of [Ar] 3d10 4s1, with a fully filled d orbital. This stability allows for unpaired electrons, making copper paramagnetic. When it forms a 1+ ion, it loses the 4s electron, resulting in a filled 3d orbital, leading to no unpaired electrons and making it diamagnetic.

The 4s orbital is energetically lower than the 3d orbital, so electrons preferentially occupy the 4s orbital first in atoms like calcium and potassium. Electrons fill orbitals based on their energy levels, following the Aufbau principle, which explains why the valence electrons of these elements reside in the 4s orbital.
The electrons in the outermost shell or orbital are called valence electrons. These electrons are involved in forming chemical bonds with other atoms.

Covalent bonds are formed when atoms share electrons. Let's take hydrogen for example. To be the most "happy" atoms want their outermost orbital full of electrons. Hydrogen has only one electron in its 1s orbital, but the 1s orbital can hold two electrons. Hydrogen wants two electrons to be "happy" so it will do what it takes to get them. If a hydrogen atom bumps into another hydrogen atom they can both become "happy" as each atom will share its electron with the other atom, giving each a full outermost orbital with the help of the other atom's electron. This is what creates the bond in covalent bond as the hydrogen atoms are "happier" together with a full orbital than they would be with a half-full orbital apart.
If the outer orbital is not full of electrons, the atom will likely form chemical bonds with other atoms in order to fill its outer orbital and achieve a stable electron configuration. This can result in the atom gaining, losing, or sharing electrons with other atoms to reach a more stable state.
A completely filled shell of electrons has 8 electrons.
The external shell of electrons is completely filled.
Helium has only two electrons. Both the electrons are arranged in the 1st energy level or 1s orbital.
