Fill in the blanks by selecting the correct word :

(i) If an element has a low ionization energy then it is likely to be ………. (metallic/non metallic).

(ii) If an element has seven electrons in it's outermost shell then it is likely to have the ………. (largest/smallest) atomic size among all the elements in the same period.

Select the correct answer — The energy required to remove an electron from a neutral isolated gaseous atom and convert it into a positively charged gaseous ion is called ………. (electron affinity, ionization potential, electronegativity)

Arrange as per the instruction :

(i) He, Ar, Ne (Increasing order of the number of electron shells)

(ii) Na, Li, K (Increasing Ionization Energy)

(iii) F, Cl, Br (Increasing electronegativity)

(iv) Na, K, Li (Increasing atomic size).

Give one word or a phrase for the following statement: The energy released when an electron is added to a neutral gaseous isolated atom to form a negatively charged ion.
