The quick answer - right from the get-go, since nitrogen is one of the most electronegative elements in the periodic table, the bond it forms with hydrogen will be the most polar out of all those listed. The polarity of a bond is given by the difference in electronegativity between the two atoms that form said bond.

Fluorine is a chemical element with the symbol F and atomic number 9. ... As the most electronegative element, it is extremely reactive, as it reacts with all other elements, except for argon, neon, and helium.

Radium is in group 2/IIA, and all of the elements in that group have two valence electrons. You can also determine the number of valence electrons from its electron configuration, which is [Rn]7s2 .

Heteronuclear atoms with an electronegativity difference < 1.5 are considered mainly covalent bonds. The electronegativity of Ag is 1.9 and that of I is 2.5 so their difference is 0.6, which is well below the 1.5 "cut-off."

The Group 2 atoms have 2 valence electrons. The Group 3 atoms have 3 valence electrons. The Group 4 atoms have 4 valence electrons. The Group 5 atoms have 5 valence electrons.

The two most reactive groups of elements are the alkali metals and the halogens, because of their valence electrons. Those groups have 1 and 7 valence electrons, respectively, making them desperate to bond to something, to achieve a stable configuration of 8.

Chlorine is the element with highest electron affinity. Even though fluorine is the element with most electronegativity, because of its small size, it experiences more repulsion when adding one more electron to attain stable electronic configuration.

Explanation: All the noble gases except helium and neon form compounds with highly electronegative elements. ... The calculated electronegativity of Ne is 4.8. Here's a Periodic Table that includes the electronegativities of the noble gases.

A metal atom bonded to highly electronegative elements. This will allow the central atom to accept an electron pair as it is left with a large partial positive charge. Any old electrophile will act as a Lewis Acid since electrophiles are seeking electron pairs.

The bigger the electronegativity difference is between the two atoms, the more ionic the compound is. For example, Na2O is more ionic than Cl2O because Cl and O are closer in electronegativity. Electronegativity is greatest in the upper right corner of the periodic table.

Elements that tend to gain electrons to form anions during chemical reactions are called non-metals. These are electronegative elements with high ionization energies. They are non-lustrous, brittle and poor conductors of heat and electricity (except graphite). Non-metals can be gases, liquids or solids.

What is the periodic trend for electronegativity? Electronegativities generally increase from left to right across a period. This is due to an increase in nuclear charge. Alkali metals have the lowest electronegativities, while halogens have the highest.

The 38 elements in groups 3 through 12 of the periodic table are called "transition metals." As with all metals, the transition elements are both ductile and malleable, and conduct electricity and heat.
