244 An interesting answer...I would have thought that they all have 2 electrons in the outer shell in their ground state.
Group 3 is part of the transition metal series. This means that the number of outer shell electrons the element has will depend on its oxidation state.
The total number of electrons in p orbitals in a palladium atom in its ground state is 18. The number of electrons present in the p orbitals in the outermost electron shell of the halogen atoms is five.
2 valence electrons are in an aluminum atom in the ground state.
Titanium atoms have 22 electrons and the shell structure is 2.8. 10.2. The ground state electron configuration of ground state gaseous neutral titanium is [Ar]. 3d2.
It is n=4 because Br is in the 4p valence shell.
A duplet state is when an element has two electrons in it's outermost shell For example-Helium
C = 1s2,2s2,2p2 so the outermost (2p) orbital has 2 electrons in Ground State
The electronic configuration of Bromine in its ground state is: 1s2 2s2p6 3s2p6d10 4s2p5. Therefore the principal quantum number for the outermost electrons in a Bromine atom is 4.
In its ground state it does.

Valence electrons are the electrons least tightly held by the atom and by definition are the electrons in the outermost shell of the electron and are highest in energy. They are the electrons that often contribute to an elements reactivity and in the case of Sodium, which as one valence electron in its ground state, it "gives up" its electron when it comes in contact with water.
Calcium atoms have 8 electrons in the second energy level. However, they are not the valence electrons. The outermost electrons in a calcium atom in the ground state are 2 4s electrons. So calcium atoms in the ground state have 2 valence electrons in the fourth energy level.
They do not differ in any way, except they are the 1 to 8 electrons in the highest energy ground state orbitals of that atom.
The total number of electrons in p orbitals in a palladium atom in its ground state is 18. The number of electrons present in the p orbitals in the outermost electron shell of the halogen atoms is five.
