• ### What is the first ionization energy?

• First ionization energy shows periodically through the table of elements in a repetitive pattern. First ionization energy is the amount of energy required to remove an electron from one mole of gaseous atoms to produce one mole of gaseous ions with a positive charge.

• ### How to calculate the ionization energy of an electron?

• Ionization energy for the removal of an electron from a neutral atom can be calculated, by substituting, the orbit number of the electron before transition as 鈥榥 1 鈥?and orbit number of the electron after transition as 鈥樷垶’ (infinity) as 鈥榥 2 鈥?in Bohr鈥檚 energy equation.

• ### Why is the second ionization energy higher than the first?

• Each succeeding energy is larger than the preceding one. Second ionization energy is higher than the first ionization energy because removing the first electron gives the atom stable electron shell like an alkali metal but removing the second electron involves a new electron shell that is closer and tightly bound to the atomic nucleus .

• ### How do you calculate the ionization potential of hydrogen?

• Ionization potential for hydrogen can be calculated using the following equation: E = hcRH (1/n 2), where E is energy of the electron (or the amount of energy it takes to remove the electron, ionization energy) h is Planck鈥檚 constant = 6.626 * 10 -34 Js (joules*seconds)
