Answer:
Lithium has the greatest difference between its first and second ionization energies.
Answer:
290 N
Explanation:
Total downward force = Force applied on the door in bringing it down + weight of the door
Total downward force = 80 + 210
Total downward force = 290N
Answer:
Electrons do not follow specific paths, so the area in which an electron is more scientifically accurate is at the orbitals.
Explanation:
As we know in an atom various electrons are present, they are filled in the orbitals in order to decrease the energy of the atom. These electrons inside the orbitals are arranged from smaller to larger. The lowest one is filled first, the order in which energy is filled is like 1s, 2s, 2p,3s3p,4s,3d etc. The electrons that present far away from the nucleus have the highest energy, the electrons present in the first orbital from the nucleus hold less energy.
