Why are Na+ and K+ unable to form covalent bonds?

Ionic compounds like CaCO3 contain polyatomic ions. Explain the formation of CaCO3 which contains a polyatomic ion. Use evidence from the table.

Draw the Lewis model for Na+

Metals in group 2 of the periodic table form ionic bonds in a one-to-one ratio with nonmetals in group O 15 O 16 O 17 O 18 1 围 DELL

please answer this question correctly. 1. Write the general noble gas configuration for a group 17 (7A) ion.

Why can dissolved ionic compounds conduct an electric current but dissolved covalent compounds cannot?

Which of the atoms listed as choices could be expected to form a +2 ion in an ionic compound? O Na U Ba Al Br Ca M

Based on your answer to part b, and what you have learned so far, which anioningroup 7 should have the largest ionic radius (consider only F-1, Cl-1, Br-1 and I-1)? Why?

Are the bonds in NH4+ ionic or covalent bonds? Explain your answer.

Group the following  ions into one of two groups based on the ion size compared to itsrespective neutral parent atom: (1) larger ionic radiusthan neutral atom OR (2)smaller ionic radiusthan neutral atom. Ions - Li, Be, N, O, F, Na, Mg, Al, P, S, Cl, K, Ca   Explain BOTH of the two groupings based on the principles of attractive/repulsive forces between theelectron(s) and proton(s) and how those forces affect the distance between the nucleus and atom’s vsion’s valence electrons.
