- Of the five elements Sn, Si, Sb, O, Te, which has the most endothermic reaction? (E represents an atom.) What name is given to the energy for the reaction? E(g)E+(g)+eConsider the following statement "The ionization energy for the potassium atom is negative, because when K loses an electron to become K +, it achieves a noble gas electron configuration." Indicate everything that is correct in this statement. Indicate everything that is incorrect. Correct the incorrect information and explain.7.21 Theoretical models for the structure of atomic nuclei predict the existence of superheavy elements that have not yet been discovered and suggest that such elements might be fairly stable if they could be produced. So researchers are currently trying to synthesize these superheavy elements to test these theories. Element 117 has been synthesized and named Tennessine (Ts). What would the Lewis dot symbol be for this new element?
- magnesium is it stable or reactive? why? if it reacts with another atom, would it be more likely to accept or to donate one or more electron?Elements A and B are in the same row of the periodic table. Element A is closer to the right side of the table than B. Element A likely has a smaller ionization potential. O Agree O Disagreemichael CHM 1045 (Post Lecture Homework Chapter 08 lonization Energy I Review | Constants Pe lonization energy (E) is the amount of cnergy required to remove an electron from a neutral gaseous alom or gaseous ion. Electrons are attracted to the positively charged nucleus; therefore removing an Part A electron requires energy. The process is cndothemic, and so ionization encrgies have a positive value.
