As the nuclear charge increases from neon to calcium, the orbital energies

As the nuclear charge increases form neon to calcium, the orbital energies

When an electron with charge .e. and mass .m. moves with velocity .v. around the nucleus having nuclear charge .Z. in a circular orbit of radius .r., the potential energy of electron is

An energy of 68eV is required to excite a hydrogen like atom from its second Bohr orbit to the third. The nuclear charge is Ze. Find the value of Z, the kinetic energy of the electron in the first Bohr orbit and the wavelength of the radiation required to eject the electrons from the first Bohr orbit to infinity.

What happens to the nuclear charge with increase in atomic number?

An energy of 68.0 eV is required to excite a hydrogen-like atom in its second Bohr orbit to third. The nuclear charge is Ze. Find the value of Z, the kinetic energy of the electron in the first Bohr orbit and the wavelength of the electronmagnetic radiation required to eject the electron from the first orbit to infinity.

In a period from left to right A) nuclear charge increases B) effective nuclear charge increases C) atomic size decreases D) Ionisation potential increases Correct among the above are
