Question

question 5 6 pts in any period, the highest electronegativity is found in a metal. nonmetal. metalloid. question 6 6 pts a polar covalent bond will form between which two atoms as shown in the following combinations? beryllium and fluorine hydrogen and chlorine sodium and oxygen fluorine and fluorine

Explanation:

Electronegativity increases across a period from left - to - right. Nonmetals are on the right side of the periodic table and generally have higher electronegativities. For polar covalent bonds, they form between atoms with an intermediate electronegativity difference. Beryllium and fluorine have a large difference (ionic character), sodium and oxygen also tend to form ionic bonds, fluorine - fluorine is non - polar covalent as it's the same atom. Hydrogen and chlorine have an appropriate electronegativity difference for a polar covalent bond.

Answer:

Question 5: nonmetal
Question 6: hydrogen and chlorine
