What element is a radioactive element
What element is a radioactive element?
Which electron is on average further from the nucleus an electron in a 3p orbital or an electron in a 4p orbital
An electron in the 4p orbital is, on average, further away from
the nucleus than an electron in the 3p orbital.
If a Hypothetical atom has energy levels from lowest to highest as n equals 1 n equals 2 and n equals 3 For an electron in this atom to move from n equals 1 to n equals 3 orbit the electron must
Absorb appx 12.1eV (electron Volts) of energy. Energy of 1st level is -13.6eV
Energy of 3rd level is -1.5eV Hence, energy required = 13.6 - 1.5 = 12.1 eV
Which level in energy has the less energy n equals 4 n equals 3 n equals 2 n equals 1
n=1 is the the lowest level there is.
