Explanation / Answer

Which questions do you want to be solved? You are putting a lot of questions here, And it will take a very long time to answer all of them in one single post. I hihgly recommend you that post single and few questions per post, in that way you may get answered faster and better.

I'll take a guess ans answer the 3 marked questions there and answer those. If you wish to get answered to all the other questions, then post them per separate in different posts. Maybe 3 questions per post. It will take longer to post, but you'll get faster answer for all of them.

Question 51.

Ionization energy raises whenever you go up and to right in the periodic table. With this said, you may say that Fluorine has the greater ionization energy. And the atomic radius is the opposites, it raises whenever you go down and to the left of the periodic table. Therefore, for an atom with an atomic number higher than Tc, I will expect a higher ionization energy (>869 kJ/mol) and a lower atomic radio (<143); in this case, Option A would be the correct answer (Radius of 133 pm and energy of 1009 kJ/mol)

Question 33.

size of the container will not affect the rate of effusion, because the pressure will be maintained. the most important is pressure.

Question 64.

A covalent compound is made when two or more nonmetal atoms bond by sharing valence electrons. Following this definition, The HCl would be a covalent compound. The rest of the compounds there are ionic compounds.

Hope this helps
