Question 4 (1 point) Which element has the smallest ionization energy? Ова и ООО о з Оне

Answer 1

Ionization energy is the quantity of energy that on iscelated gaseous atom in the ground electronic State must absorb to discharge an election, resulting in a Cation Tonization energy trends. The ionization Energy of the elements within a period goue salles increases from left to right. This is due to electron shielding The ionization energy of the elements within a group | genorally decreases from top to bottem because increase of size of elements. It is easier to remove an electron from a large size element than lower size of element Noble gases possess very high ionization energies because e of their full Nalence Shells. -- → He is a noble goue betay It is a small size element Electron of He is so close to nucleus and unscreened: so, Tenizabice energy of the is high = Flourine (F) has a higher ionization energy because valence electrons of fluorine are attracted more strongly to its positively charged atomic nudler. This is because fluorine atoms have only two energy levele, So there. is no significant shidding effect. Therefore it requires a higher lonization energy to remove a valence election from fluorine oxygen (0) has higher lonization than cs due to as more in period from left to right, the atomic number increases which means that the heilear Charge increaty.

Is atom has smallest Size As move down a decreases because it is larger size atom than attraction gets decrease electron jonization energy due to its largos group , the ionization energy easier to remove on election from smaller As size increceses, nuclear & hence it is easy to remove on um Barium (Ba) is first net of ca in period of periodic table. As we know, Jonization energy increases as we move from left to right in periodic table due to decrease of size of atom So Tonization energy of Ba is higher than the ca So, smallest & he es ionization enthalpy among found in ea (cesium) Ba, f ,O, as Now Answer is @ CA
