Ne has three p-orbitals.
Ne has three p-orbitals.
[Ar]4s13d5 why is it arranged in this way is simply because a fully occupied is more stable than half occupied and partially occupied at last.
Argon (Ar) is an atom not a molecule. An atom is singular whereas a molecule is a group of two or more atoms.
3s and 3p
They have the same number of electrons. A neutral Ca atom would have 20 electrons but because it is a Ca2+ ion it only has 18 electrons (the same as Ar).
Arsenic is paramagnetic because the electron configuration is {Ar}4s^2,3d^10,4p^3. Due to the unpaired electron at the end (4p^*3*) the atom in ground state is paramagnetic. **OR Arsenic would be paramagnetic since the 4 p orbitals each contain one electron with parallel spin. These three unpaired electrons give arsenic its paramagnetic property.

All of the Nobel gases do (He Ne Ar Kr Xe and Rn)
The number of atoms in 1/2 gram of the chemical element copper is 4.7384X10^21. Copper has the atomic number 29 and its symbol is Cu.
Argon (Ar) is an atom not a molecule. An atom is singular whereas a molecule is a group of two or more atoms.
[Ar]4s13d5 note it is NOT [Ar]4s23d4. The reason for this is to achieve maximum spin multiplicity and hence lowest energy, the first arrangement gives 6 half - filled orbitals (maximum spin multiplicity) whereas the 2nd arrangement gives on 4 half filled orbitals.
there is only one unpaired electron in copper
* Ground state electron configuration:[Ar].3d10.4s2.4p6 so...4s and 4p
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
i wish i knew. I'm learning that. I'll answer later.
Argon is a non metal element. There are 18 electrons in a single atom.
there are 19 protons, neutrons and electrons
